A Comment on Throat Erosion from Scott Duff
It has come to my attention
from discussions with many M1 Garand owners that a misunderstanding of an
acceptable versus an unacceptable Throat Erosion (TE) reading exists. A note of clarification is in order. When
discussing serviceability specifications of U.S. Martial Arms, it is best to
review the primary source, the U.S. Army Ordnance Corps documents from when the
M1 rifle was the issue rifle to front-line troops. I have in my files TB ORD
587 dated 20 December 1954 entitled Field Inspection and Serviceability
Standards for Small Arms Material. A chart on page four outlines the
serviceability specifications for the M1, M1C, and M1D rifles “To Accompany
Troops Overseas.” The specification given for “Breech Bore Rejection” is “Over
0.306” or a TE reading of 6 on a gage. No specification is given for muzzle
wear. If combat troops in the 1950s were issued rifles with a TE of 6 or under,
then the same is good enough for a rifle in my collection. I would not go to
the John C. Garand Match at Camp Perry with a rifle with a TE of 6, but for
general collecting, in my opinion, it matters little.
This is also a good time to
note that based upon my observations the TE of a new production SA barrel
during World War II ran anywhere from approximately 1.0 to 3.5. Pre World War
II SA barrels were usually in the 0.0 to 1.0 range. Winchester barrels were
generally in the -1.0 to 2.0 range, but I have seen new WRA barrels with higher
and lower readings. An expanded version of this including information on post
WII barrels will be published in a future issue of the Garand Collectors
Association Journal (GCA). If you are not a member of the GCA and would like to
join (as an M1 owner you really should be a member just as a gun owner you
should be an NRA member) you may download a membership application from the GCA

!!SOLD!! 010-R1321. M1 Garand, Springfield Armory, Air Force Premium Grade (AFPG)
Rifle s/n 5416440. This is the first AFPG M1 we have been able to offer
since 1998; they are very scarce. The AFPG rifles were built in the 1960s as
match rifles by the Air Force Marksmanship Training Unit (MTU) at Lackland AFB
near San Antonio, Texas
for use in competition by the Air Force Rifle Team. There are several
variations of AFPG rifles and all variants share common features that make them
readily identifiable - if you know what to look for. I learned the details of
the AFPG M1 rifles from a lengthy telephone conversation with the man who
worked in and later ran the MTU shop at Lackland for 25 years. Details will be
provided in a future issue of the GCA Journal (You are a GCA member? If not,
you should be.) Basic details are that the AFPGs were fully glass bedded and
the stocks and hand guards were sealed. The stocks were marked on the flat to
the rear of the stock ferrule with the last four digits of the s/n and the
month and year the rifle was built. The stock ferrules were attached to the
stock with countersunk flat head wood screws. Some contained .30-06 barrels
that were sleeved with a USN Mk 2 Mod 0 type chamber sleeve and others were
built using 7.62 MM NATO barrels made by SA in the 1960s for the Navy. The bolts
were marked 7.62 MM with electro-pencil etching of that information. Some had standard
SA-type 1/2- minute NM rear sights and others had the windage knob modified
with eight notches and the receiver drilled and a spring and detent installed to
allow 1/2-minute adjustment. The bolt lugs and underside of the barrels were
heavily polished. Of course they also had the usual match modifications, such
as tuned triggers, unitized lower band and hand guard, etc. They were also
marked AFPG on the barrels when built. The rifles were then shipped from
Lackland to Warner Robins AFB in Georgia
for distribution to the rifle teams. Many AFPG M1s do not have the AFPG
markings on the barrels. When the barrels were shot out, the rifles were not
returned to Lackland for re-barreling. They were re-barreled wherever was convenient,
such as at Camp Perry in the Air Force gun van, or if the rifle was at Warner
Robins they were re-barreled in the Army MTU at Fort Benning. When they were
re-barreled they were not marked AFPG, but they are still identifiable as AFPG
rifles. This particular rifle has a SA 10-65 7.62 MM barrel with bright and
shiny bore, TE = 1.5, MW = 1.0+, the op rod engagement are of the barrel is
heavily polished, and no AFPG marking. The bolt is marked 7.62 over MM and the
bolt lugs are polished. The op rod is a 7790722-RA NM. The lower band and hand
guards are unitized. The stock is marked 6440 and 4 66 to the rear of the stock
ferrule, indicating the last four digits of the s/n and the month and year of
the build. The stock ferrule is attached to the stock with screws. The walnut
stock and hand guards are sealed. The trigger pull is tuned. The rear sight
base is a NM/2A with NM windage knob, and 695 1/2-minute hooded aperture. AFPG Match Rifles are scarce and rarely
encountered by collectors. If you collect M1 match rifles, don’t pass on this
one. - $2,595







!!SOLD!! 010-R1322. M1 Garand, Springfield Armory, s/n 5878217 (1956). This is an excellent condition, original late production rifle, most
likely sold by the CMP. The SA 5-55 barrel has a bright and shiny bore,
TE = 1.5, MW = 0.75+. All expected 65-code SA parts. The stock is very nice
looking well struck DAS cartouche and proof P in a circle with only a few very
minor handling and storage dings. This is a very nice looking rifle that would
be difficult to improve upon. - $1,595




!!SOLD!! 010-R1323. M1 Garand, Springfield Armory, s/n 6085498 (1956).
This is a 100-percent original example of a tough-to-find late M1 that
is in very good condition. The SA 3-56 barrel has a bright and shiny bore, TE =
2.0, MW = 1.5. Featured are all expected 65-code SA parts and a very good
condition stock with good Defense Acceptance Stamp (DAS) and proof P in a
circle. Sale includes an M1 web
sling. This is a great example of a scarce rifle that is missing from most
collections. - $2,595





From Mac’s
Collection !!SOLD!! 010-R1324. M1 Garand, Winchester Repeating Arms Co., s/n 1284431 (Feb.
1943). This is a restoration that was performed on an excellent condition
original receiver/barrel and rear sight assembly using original finish parts.
This is a very good looking fairly early rifle. Sale
includes the original Nov. 1996 dated CMP release paper. The Winchester
barrel has a bright and shiny bore, TE = 1.5, MW = 0.75, with no chrome at the
gas port. Featured Winchester components include: bolt, unmodified op rod,
bullet guide (CM), early follower, early op rod catch (A), single bevel
follower arm (.), clip latch (A), follower rod (A), grooved rear hand guard
clip, lower band, narrow base gas cylinder with original DuLite finish, single
slot gas cylinder lock screw, complete rear sight assembly filled with
Cosmoline and pinion staked (most likely original to the receiver), complete trigger
housing, trigger guard, hammer, safety, and re-Parkerized butt plate (the only
non original finish part on the rifle). The long channel Winchester
stock is in very good condition with well struck WRA/GHD cartouche, Ordnance
emblem, and proof P. The rear hand guard is the type with the machined
clearance cut for the op rod and is too early for this s/n WRA rifle. The hand
guards match the condition of the rear. This is an outstanding example of fairly
early WRA M1 rifle production. Other than the rear hand guard and the butt
plate, this looks like an original rifle and most collectors would have
difficulty in determining that it was in fact restored. In today’s market you
could not restore this rifle for the asking price. - $2,895








!!SOLD!! 010-R1325. M1D Garand, Springfield Armory, s/n 2155083, CMP Sales Rifle. This is one of the more
unusual M1Ds I have ever seen. It is a CMP sales M1D rifle (NSN 1431) that was
sold by lottery in November 1998 and came equipped with a Lyman All-Weather
Alaskan scope (s/n B6271) instead of the usual M84. The sealed bag was marked
M84 with a s/n of B6271 written in ink; that is not an M84 s/n. I had previously
heard of several CMP sales M1Ds so configured, but this is the first that I
have seen myself. Included with the sale of the rifle are the original papers,
box, and all packing material for the rifle and Basic Issue Inventory (BII). A
print out of an email about the scope between Dave McClain and one of the
previous owners is also included. In addition to the very desirable scope, this
rifle is in unissued condition. The black Parkerized finish is in excellent
condition throughout. The SA 5-51 barrel has a bright and shiny bore, TE =
2.25, MW = 0.75. The walnut stock is in excellent condition with SA over M cartouche,
RA stamp, and three proof P stamps in circles. The walnut hand guards are in
excellent condition and match the stock. Included with the BII is a 7/8-inch
scope mount, the aforementioned excellent condition Lyman All-Weather Alaskan
scope with cross-wire reticle and rubber eyeshield, thin bracket M2 Hart flash
hider, an excellent condition T4 cheek pad (MRT/1-52), M65 scope case, and excellent
condition M1 web sling. This is an excellent condition example with a rarely
encountered scope variation that would never need to be upgraded. - $4,295









From Mac’s
Collection 449-R1307. M1D Garand, Springfield Armory, s/n 3576897, RARE variant with 1-inch mount and Weaver K-4
scope. Based on the appearance of this rifle it is my opinion that Mac
built it from a loose receiver and loose US GI M1D barrel. I do know that quite
a few years ago he did have a few loose US GI M1D barrels. I have priced this
rifle as it not being CMP sales. The rifle is equipped with a 1-inch scope
mount and Weaver K-4 scope rather than the more common M84 scope and 7/8-inch
mount. This is a rare variant. The Parkerized finish of the receiver is a
uniform flat black in color over light speckling in the base metal. I recognize
this finish as the Parkerizing that Mac was doing in his shop about ten years
ago. The US GI SA-1-52 M1D barrel (drawing number D7312555 underneath the rear
hand guard) has a bright and shiny bore, TE = 2.0, MW = 1.0. The walnut stock
and hand guards are in excellent condition. I did not remove the cheek pad to
check the stock for a cartouche. The stock has two proof Ps in a circle and a
proof P that is not in a circle. Accoutrements include: 1-inch scope mount,
Weaver K-4 scope with bright and clear optics, proper lense cover, US GI T37
prong type flash hider (with white ink DAS stamp on the bottom), US GI T4 cheek
pad marked MRT over 11 62, and M1 web sling. Only a small percentage of the M1D
rifles were equipped with the 1-inch mount and Weaver K-4 scope; few collections
include one. A loose 1-inch M1D mount with Weaver K-4 scope and lense covers
command a significant premium over the 7/8-inch mount and M84 scope. This is a
very nice looking example. Sale
includes Letter of Authenticity to Mac’s collection by Scott Duff. - Reduced to $3,225!




From Mac’s
Collection !!SOLD!! 379-R1276. M1 Garand, Harrington & Richardson Arms
Co., s/n 4660861 (1953). This is one of the rarest, and in my opinion, one
of the most interesting of HRA M1 rifle variants. HRA began production at s/n
4660000; this rifle is only 861 numbers into H&R’s assigned serial number
range. This is an original rifle with the exception of the bolt, which has been
added to make the rifle correct. It is exactly as those described in the
article I wrote for the Garand Collectors Association Journal, Volume 15,
Number 4 and includes the World War II era parts that are typical of HRA M1s in
this serial number range. Overall, it is in very good condition. The HRA 4-53
barrel has a bright and shiny bore, TE = 2.0, MW = 1.0. Featured parts include:
HRA D65 bolt, 6 SA op rod with modification cut, early WRA op rod catch,
6528290 HRA H trigger housing, SA revision 9 hammer, HRA safety, DRC
windage knob, W in a hexagon elevation pinion, HRA gas cylinder lock screw, and
HRA stock with deeply struck Ordnance emblem on the left side and proof P. The
stock and hand guards are in very good condition. The early HRA similar to this
one is one of my favorite post WWII rifles in my collection. The use of WWII SA
and WRA parts by HRA early in production is an interesting part of the early
1950s M1 rifle production story. This is a scarce and very desirable rifle that
is missing from most collections. - Reduced to $3,295!




299-R1255. M1 Garand, Springfield Armory, s/n 3810522 (June 1945). This is an old DCM (forerunner of
the CMP) sales rifle from March 1986 when the policy was one-in-your-lifetime. This is a very nice looking restoration of a
late WWII rifle. It is based on
an old US GI re-Parkerized finish receiver. The Parkerized finish on all
components is in very good to excellent condition. The original SA
5-45 barrel has a bright and shiny bore, TE = 2.75, MW = loose, Parkerized chamber
mouth, and no chrome at the gas port. Featured parts include: -19 bolt,
unmodified revision 9 flat side op rod, -18 trigger housing, -9 hammer, SA_11
safety, WWII stamped trigger guard, 13 follower, type 3 lock bar rear sight,
and all other expected parts. The stock is in very good condition with
well-struck NFR cartouche, Ordnance emblem, and proof P. Sale includes a M1907 leather sling marked
MILSCO 1943 (easily worth $125 to $150) which is reflected in the price of the
rifle. Also included are the original DCM box, four DCM documents, and manual. The
owner’s name and street address have been concealed for their privacy on the
Internet posting only; the original box label and document are intact and will
be provided to the buyer. This is a
very nice looking late war example. - Reduced to $1,425!







From Mac’s
Collection 199-R1208. M1 Garand, Winchester Repeating Arms Co., s/n 165494 (May 1942).
Winchester’s first assigned serial
number block was 100001 to 165500. This rifle is the highest know serial number
in that first block. In my opinion that is pretty cool! The rifle is a
restoration with the receiver being re-Parkerized and two-tone, indicating that
it had been lead pot annealed. The Winchester
barrel has a bright and shiny bore, TE = 1.0, MW = 2.0, with no chrome at the
gas port. Featured Winchester
components include: bolt, round firing pin (.), extractor (.), unmodified op
rod, early narrow slot bullet guide (B8875W.R.A.), early follower (CM), early
op rod catch (CM), single bevel follower arm (.), clip latch (CM) follower rod
(CM), grooved rear hand guard clip, lower band, narrow base gas, front sight,
single slot gas cylinder lock screw, rear sight base (CM), cover without ribs,
aperture (CM), long pinion with type 2 lock bar, checkered windage knob,
checkered elevation cap, single hole large pad trigger housing (CM), trigger
guard, hammer (CM), trigger with extra hole, safety (C46015-4W.R.A.), and forged
stock ferrule. The trap-type butt plate is a mid WWII SA. The stock has a visible WRA/WB
cartouche, Ordnance emblem, and proof P in a circle. The stock also has a CSAA
(San Antonio Arsenal) rebuild stamp on the left side and three proof P stamps. The
stock has been sanded and scrapped on the sides and has a few chips out of it
at the butt plate. The rear hand guard is the early type without the machined
clearance cut for the op rod. The front hand guard matches the condition of the
rear. If you want to own the highest know s/n in Winchester’s
first block, this rifle is for you. - Reduced to $2,850!

________________________________________________
U.S. Navy M1 Garand (and other) Rifles (FFL Required)
The following is a listing of Secretary of the Navy Trophy rifle variations:
M1 Rifle Mk 2 Mod 1 Grade B match rifle in 7.62 MM with 1-minute sights. Grade B match rifles were first released by the Navy as a Trophy Rifle in 1996. They are very desirable collector pieces.
M1 Rifle Mk 2 Mod 1 in 7.62 MM using a new SA produced barrel (1965-67 mfg.), two sub-variations; one converted by Harrington & Richardson (H&R) the other by American Machine & Foundry (AMF) of York, PA. The AMF version is by far the rarer of the two (possibly only 10%). These variants have become very scarce over the last few years.
M1 Rifle in caliber .30-06. Often marked “O-65, O-66 or O-67” on flat of
receiver behind rear sight. These are usually encountered in unissued condition following rebuild. According to Jeremy Cheek's published article in the June 2004 issue of the Garand Collectors Association Journal, these rifles are USMC M1 rifles rebuilt at Marine Corps overhaul depots.
Remington Model 720 bolt action rifle. These rifles were purchased by the Navy from the Remington Arms Co. immediately following the attack on Pearl Harbor. Their hand-cut checkering is an
example of pre-War craftsmanship. They have become very rare and are highly sought after by collectors. They look nearly like works of art.
Navy non-Trophy Rifle variations are:
Mk 2 Mod 1 Grade A match rifle in 7.62 MM with ½-minute sights. They are the rarest of all; it is believed
that few, if any, have been released by the Navy. I’ve never seen one.
Mk 2 Mod 0 in 7.62 MM using a .30-06 barrel with insert to convert to 7.62. This is also a very scarce variation and highly sought after by collectors. I have only seen a handful of real ones in over 15 years.
