Current Stock:

The MPX patriot mag lock from Bullet-Button is installed with the "removable" adjustment screw permanently fixed and blended to aid in smooth closing and a tight fit. The hole in the patriot for installation is filled with a black resin to comply with permanence. The patriot device itself is often reblended and beveled to ensure a smooth action while the action is disassembled. The folding stock is pinned by replacing the pressure-plunger in the folding stock mechanism with a bolt and spacer. If it is the wire-frame telescoping variant, the stock is pinned in a non-destructive manner to comply with OAL.
