lower and JP Enterprises bolt carrier group compatibility
They fit, with a catch
The Cross Machine Tool UHP15 Billet Stripped works with the JP Enterprises EnhancedBolt BCG 9mm QPQ Finish, with one thing to check: Lower Receiver (AR-15) needs a 9mm magazine well adapter for a PCC/9mm build.
Checked by the same rules the AR builder runs on every part you add: caliber, frame size, receiver pattern, thread pitch and gas length.
Fit is judged from the specs retailers list, which can be missing or wrong. Confirm with the manufacturer before you buy, and have a qualified gunsmith check any build before you fire it.

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.
