Use these adapters to put the B&T MP5 polymer side folding stock on your BREN 2. Also can be used to put the SB Tactical MP5-style arm brace. Manufactured from durable MJF Nylon, the adapter uses a polished and hardened step pin on the hinge instead of the standard roll pin.
We have tested this mount with over 1000 rounds to date and still going. The gas system allows a light recoil spring on this firearm so there is not a lot of tension on the rear plate, making a polymer version possible for this application.
Note that the stock/brace clears the ejection port and the firearm can be fired while folded.
Using the hinged adapter provides a positive latch when the stock is opened but the B&T stock/SBT brace has no provision to latch in the folded position.
NOTE: Stock/Brace pin bore requires simple modification with 3/16" drill bit.
