SC Rifleworks SC-M40 Tactical Rifle
SC-M40 as it comes from the SC factory.
Currently No Longer Produced
In honor of past US Combat snipers, SC Rifleworks was proud to build the SCM40 sniper
rifle. The SC-M40 is a replica of the USMC M40 sniper rifle of 1966. The M40 served
the USMC from 1966 through the end of the Vietnam conflict with a total of 750 having
been produced. Because of the pressing demand for an official USMC adopted sniper
rifle to replace the M70/Unertl target rifles (being used as sniper rifles) with a
lighter rifle that allowed quicker times to get off the first round, the Weapons
Training Battalion conducted a comparative test of commercial rifles and telescopes.
They concluded that the Remington 700 combined with the Redfield accu-range 3-9x
telescope was "superior to items now in use." On April 7, 1966 the Model 700 and
Redfield scope were officially adopted as the "Rifle, 7.62mm Sniper, M40". The rifles
were "off the shelf" Remington 700's with a heavy barrel, the muzzle diameter being
.830". The stock had a dull oil finish and the barrel and action were parkerized. The
floorplate and bolt shroud were "colored black" and the bolt was finished in a very
matte black. The barrel was free floating and the action was
NOT glass bedded. The special Redfield scope was anodized green and had the accu-range
reticule. The rifle proved effective during the conflict, though the scope was a bit
fragile and the rifle had its problems. But it was a good first step of which was
later modified into the M40A1 which served for 30+ years.
The SC-M40 was a 96% replica of the original M40 with some improvements. The largest
of which is the bedding on the rifle. While we are keeping true to the original
M40 and not glass bedding the rifles, we are doing the next best thing, using
an Accurate Innovations ® walnut stock with their patent pending aluminum bedding
A look at the aluminum bedding block
The Stock is finished in a dull linseed oil finish and is made as close as possible to the original
Remington walnut stocks of the era. This includes a monte carlo cheekpiece as was found
on the original M40's. The bedding block gives you all the benefits of a fine bedding
job and the durability of aluminum. The bedding blocks are also sitting in the stock on
top of aluminum pillars for the mounting screws to travel through. While the original
M40's used a steel buttplate, we have strayed a bit and opted for a hard plastic
buttplate (with a small amount of rubber) to look original, but keep the costs reasonable.
The SC-M40 shown on this page uses a prototype version of the stock, the others we built
for customers have a stock with some minor tweaks to get it very close to factory original
The SC-M40 was built using new Remington 700 actions that had been squared and trued by SC Rifleworks and have
had their lugs lapped. The serial numbers were obviously very different from the
original six digit numbers on the M40's, and also, here is the biggest deviation from
the original M40's: Due to practicality and cost, there were no stripper clip slots on
top of the action as there was on the M40's. Obviously a useless feature when a scope
is mounted. The actions had a hand lapped Montana Rifleman barrel of the proper contour
attached. The barrels had the correct 1:10" twist for the M40's (which the current
remington Commenerative M40's do not have) and had a 11 degree
target crown which is an improvement over the original M40 flat crowns. The barrels
were also properly marked with the "7.62 NATO" marking.
Proper barrel markings.
The barrel and action were parkerized as were the original M40's. The bolt on the originals
were a very dull black and the aluminum floorplate and bolt shroud were black. We ceramic
coated the bolt in a "military" black and ceramic coated the floorplate and shroud in a
satin black. While these colors seem like a hodpodge, it is how they came originally
(though ceramic coating is a step up).
The original Redfield accu-track scopes are no longer produced and are difficult to
find, and as is such, were not available through SC Rifleworks. But, we
did provide a very similar in outside appearance 3-9x40mm scope painted in green
dura-coat for a semi-replica appearance. The factory prototype rifle pictured on
this page had a later
generation Redfield accu-track scope mounted with this green finish. We found this
scope on a rifle we picked up from a pawn shop.

The one big advantage of the SC-M40 over the original M40 (besides being much
cheaper than trying to procure an original) is performance. The SC-M40 does not
suffer from weather effects on the stock as the original M40's did with their walnut
stocks and no glass bedding, and the SC-M40 had
a factory guarantee of .5 MOA with match ammo (and qualified shooter).
Here at SC Rifleworks we are proud of our US Armed forces and the job that they do,
especially our snipers. This rifle was a tribute to them, and specifically to the
USMC snipers of the Vietnam conflict. We hope to be able to offer additional replica
sniper rifles in the future to further honor our snipers and the work they do.
Several months after we started these rifles, remington began to offer Vietnam Era
M40 commenerative rifles, we would like to think that they got the idea from us, but
who really knows. As it is, we no longer are offering these rifles for sale.
