Two types of AR-1 buttstock adapters are available: one designed for the Micro Roni G3/G4, and the other for the Beretta PMX. This kit enables the mounting of a Mil-Spec AR-15 stock on either platform. Assembly is straightforward, requiring the removal of the main stock pin and reusing it for assembly. Crafted from lightweight aluminum, the tube offers 6 positions, allowing you to achieve a design similar to an AR-15. It's customizable, accommodating various stock types available on the market.
