The Archangel AA9130 OPFOR Precision Stock modernizes the classic Mosin-Nagant M1891 rifle with a contemporary tactical platform built for shooters who want accuracy and handling in a traditional caliber. Constructed from proprietary carbon-fiber filled polymer, this drop-in stock transforms the ergonomics and capability of M1891, 91/30, M-38, M-44, and Chinese T-53 rifles—including both hex and round receiver variants—without requiring permanent modification. Whether you're building a precision rifle for range work or hunting, the OPFOR stock bridges the gap between vintage military surplus and modern sporting rifles.

The stock is engineered for shooters serious about accuracy. A free-floating forend accommodates most barrel contours and includes a barrel tensioner to minimize harmonics. The click-adjustable length-of-pull and rubber butt pad let you dial in your fit, while the adjustable cheek riser ensures proper sight picture alignment. The modern ergonomic grip features a comfortable palm swell and goose-neck design that feels natural under recoil. Quick-detach sling points accept standard push-button swivels (sold separately), and the stock is already inletted to accept a Timney Trigger with zero modification—a blanking piece is supplied if you keep the original trigger.

Magazine flexibility rounds out the package. The 5-round black polymer detachable magazine is included; a 10-round option is available separately if you want capacity beyond the standard five. This is a thoughtful upgrade for anyone running a Mosin-Nagant that deserves better than a slab-sided wooden furniture—expect genuine improvement in control and precision without compromising the rifle's soul.
