Franklin Armory®'s custom designed billet lowers are now available! This design incorporates integrated ambidextrous, anti-rotational Quick Detach sling mounts. On the magwell, forward of the trigger is a textured Memory Index Point for safely resting the trigger finger when not ready to fire.

The Binary Firing System GEN 3 (BFSIII®) is a 3-position trigger. In position 3, it fires one round on pull and one round on release, making this trigger ideal for both tactical and competition use. In addition, the BFSIII provides greatly reduced split times between rounds, allowing for tighter groups.

Position 1 - Safe - Will not fire

Position 2 – Semi – Fires 1 round per pull

Position 3 – Binary – Fires 1 round on pull and 1 round on release

The magazine well is also enlarged and beveled to facilitate quicker magazine changes. The integral trigger guard is over-sized to allow room for larger hands or gloves. The front of the magazine well is also textured to allow it to be used as a grip for forward support. These Built Lower Receivers come with a carbine length, 6-position collapsible stock buffer tube without any stock installed. This allows the customer to install whatever stock they prefer without paying for a generic one that they may likely remove anyway.

We have pistol braces and stocks available for purchase.
