Geissele URGI 11.5-inch on a Griffin MK2 Lower with B&T RBS-SC

A Geissele 11.5-inch URGI upper on a Griffin Armament MK2 ambidextrous lower, the builder's most-shot rifle and one they keep refining. It runs a Geissele G2S trigger with a Super 42 spring and H3 buffer, and a B&T RBS-SC Inconel can on a Comstock recessed HUB adapter. A Sig Romeo 8T with a Juliet3 Micro magnifier, a SureFire Scout and a B5 Enhanced SOPMOD stock round it out.
