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 Smith & Wesson lower and Daniel Defense upper

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