There are a few options available for mounting the Magpul ACR folding stock on an FN FAL rifle, each designed by Dan Haga or F5 MFG. Haga makes one that is well constructed but requires additional accessories like braces. F5 MFG offers its version either as an adapter or preinstalled on Grand Power Stribogs.
Adapter for CZ Bren 2
This adapter mounts the Magpul ACR folding adjustable stock onto a CZ Bren 2 rifle for significant ergonomic improvements over its factory stock, offering more comfortable optics use with better cheek weld, as well as seven position length of pull adjustment and allows the firearm to be fired while folded up.
This adapter fits onto the stock in precisely the same way and secures itself using a threaded screw threaded into the rear sling bracket screw hole for a secure, wiggle-free fit. Furthermore, it includes a rear sling bracket delete so the stock can fold thoroughly without interfering with casing ejection in most configurations.
Multi Jet Fusion or MJF technology was used to machine these Nylon components, before being sandblasted, dyed, and shotpeened for an appearance and strength that closely match injection molded nylon parts.
Adapter for CZ Scorpion
This adapter for CZ Scorpion allows the user to easily attach aftermarket pistol grips or arm braces without wiggle or play, thanks to aircraft duralumin 7075 featuring hard elox coating. Furthermore, there’s also an easy disassembly cutout in place for rear sling bracket screw holes as well as two set screws which can be tightened with 1.5mm Allen keys for rotation resistance.
This stock adapter for the CZ Scorpion EVO 3 Pistol/Carbine fits any MIL-STD-1913 Picatinny rail accessory or stock.

The CZ Scorpion Adapter Plate features three M1913 Picatinny slots to provide various height adjustment options for pistol or carbine stocks and pistol arm braces. Its beveled lines and contour are inspired by those seen on its sister, Scorpion, making for an excellent match. Furthermore, there’s a bottom-mounted quick detach sling swivel socket for use with any sling swivel system.
The HK MP5 ACR Adapter was explicitly created to fit UMAREX MP5 clones and rifles manufactured using Multi Jet Fusion (MJF).
