PSA 11.5-inch Budget Pistol on a Geissele Blem Lower with OCL Polonium

A light, mixed-parts budget build the owner put together for about $1,200: a PSA 11.5-inch complete upper on a blemished Geissele lower, braced with an SBA3. A Geissele SSA-E trigger and CMMG lower parts fill the lower, with an Aero buffer tube and an H2 buffer behind it. The builder reports around 800 rounds with no malfunctions, and runs an OCL Polonium on a Dead Air KeyMicro flash hider and KeyMo adapter.
