How we count ⌄

These shares come from GunPartPicker's build data: real parts lists people put together while planning a purchase, not sales or surveys. A build counts a part only when it is the final pick for its slot, so parts that were swapped out never count. Fit never comes from these numbers; it comes from our compatibility rules alone.

Frequently built with the Palmetto State Armory lower and Palmetto State Armory upper

The part builders pick most often in each slot alongside these two, checked against both. Parts that conflict are left out.
