Complete an AR-15 lower receiver with top quality components while saving money with these Enhanced Lower Parts Kits exclusively from Brownells.

The Geissele 2 Stage Enhanced Trigger (B-G2S-E) provides superior control and helps accuracy while maintaining the robustness and reliability that Geissele triggers are known for. The B-G2S-E gives a smooth, light 1st stage take up of 2.3lbs and a crisp, candy-cane-like 2nd stage break of 1.2lbs. The B-G2S-E is ideal for use in precision Squad Designated Marksman type rifles where weapon accuracy and reliability are critical.



The Geissele Rapid Fire Trigger (B-GRF) was developed to give semiautomatic-only rifles a glass-smooth trigger pull very similar to the Geissele Super Select Fire (SSF) trigger designed for the U.S. Special Operations Community . The B-GRF is a fast-shooting, smooth trigger ideal for 3 Gun competition and recreational shooting alike. It pulls like a single-stage, but resets like a two-stage. Two trigger springs are included so the B-GRF can be set up with a pull of either 4 lbs or 3.2 lbs. Does NOT convert semiautomatic rifles to automatic.
