Specifications
August 2026 on GunPartPicker
PSA Complete Lower 300BO, JAKL, MOE EPT w/o Brace, Smoke ranked #30 of the 507 lower receivers builders added on GunPartPicker in August 2026, behind the Foxtrot Mike Products Complete FM9 Premium 9mm AR-15 Lower Receiver, with about 1 in every 200 lower receivers added to builds. Up from #44 in July. Builds with this lower receiver are split between 300 Blackout (50%) and 5.56 NATO (50%), nearly all on pistol-length gas, and nearly all AR-15.
Availability is good: it was in stock at one retailer or another nearly every day in August 2026, and today the one retailer we track has it in stock. Prices barely moved in August 2026, holding around $237.49, so there haven't been real sales lately. Buying today, the lowest price is $249.99 at Palmetto State Armory, above August's low of $237.49, so a better deal may come back.
