The Archangel OPFOR Precision Stock is a black synthetic, fully adjustable replacement stock built for the classic Mosin Nagant M1891 and its many variants (brand part no. AA9130). Made in the USA by ProMag, it pairs an integral magazine well and patented detachable magazine system with steel pillar bedding and a free-floating barrel channel for a real accuracy upgrade over the original wood stock. A click-adjustable length of pull and cheek riser let shooters of different sizes get a proper cheek weld and trigger reach, while the ergonomic gooseneck grip adds a locking storage compartment for spare parts. It’s a complete transformation for a century-old military surplus rifle.
