We have put together a combo that allows the user to install the SB Tactical arm brace on various firearms. The SB Tactical braces are polymer constructed and include a spring-loaded button release and adjustable arm strap.
The A3 Tactical firearm adapter is MJF polymer constructed with a hardened steel pivot pin. Both pieces ship to your door assembled and install easily in 10 minutes.
Note choice of arm brace when ordering. Refer to image for desired part number.
