About this product
This is Franklin Armory's complete pistol model BLR lower receiver, fitted with the BFSIII binary trigger. In binary mode the trigger fires one round on the pull and one on the release, and the selector keeps the normal safe and semi positions. Instead of a stock, the rear end carries an SBM4 pistol stabilizing brace, so it pairs with a short AR-15 pistol upper.
The receiver is forged aluminum with a black hard coat anodized finish and a tension screw to cut upper to lower wobble. An A2 pistol grip is installed, and one 30 round 5.56 NATO steel magazine is included. The lower is the serialized part; add the upper of your choice to finish the build.
