Description
The Mosin-Nagant is a rugged old warhorse, but that heavy log of a wood stock never did the rifle any favors when it came to fit or accuracy. The Archangel OPFOR Precision Stock changes that in a big way. It's a drop-in chassis molded from a proprietary carbon-fiber and glass reinforced polymer, finished in a clean desert tan, and it turns a surplus bolt gun into something you'll actually want to shoot all afternoon. Fitment covers most M1891 rifles along with the hex and round receivers on the 91/30, the M-38, M-44, and Chinese T-53 carbines. The Finnish M-39 will fit too, though it takes some minor modification.
What the Archangel OPFOR Stock Does for Accuracy
This is where the OPFOR earns its keep. The precision inlet comes with steel pillar bedding already installed, so the receiver sits at a consistent, locked-in position every time you torque it down. Pillar bedding is normally a gunsmith job that costs real money, and here it's built in. The forend free-floats most barrel contours and includes an adjustable barrel tensioner, so you can run the barrel completely floated or dial in a little upward pressure to tune harmonics for your specific rifle.
Dialing in the Fit on Your Mosin OPFOR Build
One of the biggest complaints about the original Mosin was the awkward, short length of pull and no way to get behind a scope. The OPFOR fixes both. Length of pull adjusts with a thumbwheel across a range you can click into place, and the cheek riser raises in .05 inch increments with 1.75 inches of total travel, which is exactly what you need to get your eye lined up behind a magnified optic. The gooseneck pistol grip has ambidextrous palm swells and a rubber buttpad to soak up that legendary 7.62x54R recoil.
Features Built Into the OPFOR Chassis
The stock feeds from a detachable box magazine, so no more fumbling with stripper clips or awkward reloads under a scope. Three integral steel inserts accept QD sling swivels, and there's a lockable storage compartment tucked into the grip for small accessories. It's also pre-inletted to accept a Timney Trigger with no gunsmithing, and a blanking piece is included if you keep the factory trigger. The whole thing weighs in around 3.6 pounds and is made in the USA.

Frequently Asked Questions
Will the Archangel OPFOR stock fit my rifle?
It fits most M1891 rifles as well as the hex and round receivers found on the 91/30, and the M-38, M-44, and Chinese T-53 carbines. The Finnish M-39 will work with some minor modification. It covers both hex and round receiver variants, so most common surplus Mosins drop right in.
Do I need a gunsmith to install the OPFOR stock?
No, it's designed as a drop-in fit and comes with the hex head action screws and Allen wrench you need to get it done at home. The steel pillar bedding is already installed at the factory, so you skip that gunsmithing step entirely. Just make sure your action screws are torqued consistently for the best accuracy.
Does the Archangel OPFOR stock help with accuracy?
It does several things surplus wood stocks can't. The factory steel pillar bedding holds the receiver in a consistent position, the forend free-floats the barrel, and an adjustable tensioner lets you tune barrel pressure for your specific rifle. Add the adjustable cheek riser and length of pull and you get a fit that makes it far easier to shoot the rifle well, especially with an optic.
Can I run a scope and a Timney trigger with this stock?
Yes. The adjustable cheek riser raises your eye to line up behind a magnified optic, and the detachable magazine makes loading easy even with a scope mounted over the receiver. The stock is also pre-inletted to accept a Timney Trigger with no modification, and a blanking piece is included if you keep the factory trigger.
