The Beretta PMX is a refreshing new firearm in the PCC world and easily competes with similar firearms such as the CZ Scorpion, B&T GHM, and Grand Power Stribog. Unfortunately, the proprietary rear stock mount does not provide any options for mounting a brace so we have developed a direct-fit rear adapter that uses the existing hinge-point and latch. This adapter allows us to use our complete line of Modular brace and stock accessories, providing the user multiple options and configurations for just about all preferences. 

The adapter simply pins in place using the factory hinge-pin, and the latch button releases to fold the stock. The adapter is machined with a 3 degree downward angle to clear the ejection port when folded, so the firearm can be fired with the brace in the folded position. 

The extension arms are available in straight or offset and we offer 2 different cheek riser options.

All components are machined from aluminum and anodized low-gloss black. Made in the USA!

Extension arms are all machined from 6061 aluminum and have 3 M-LOK slots for positioning QD sling mounts and other M-LOK accessories. 

Our modular system allows the user to to configure the folder with either our Steady-brace stabilizing brace, or the Gearhead Works Tailhook brace.

Offered with either our straight or offset M-LOK extensions
Optional M-LOK mounted Quick-disconnect (QD) sling mounting socket.
CHEEK RESTS: We have 2 different cheek rests available for the AK folders - the clamp-on, non-adjustable cheek rest, or our XENO Modular cheek rest. The clamp-on is a fixed-height polymer rest measuring 4" long that raises the cheek rest 1/2". The Xeno Modular Rest can raise the cheek rest 5/8", 7/8", or 1-1/8". The XENO mounts via M-LOK and also has an offset that allows the cheek rest to be positioned 1" offset of the mount, if necessary. The XENO has an aluminum mount with injection-molded Polymer spacers and cheek rest.
