5 of 5 P80 LPK works great July 20, 2026
: Kez from Bethlehem, PA United States  
Overall, this is a quality frame parts kit with one important thing to be aware of: it does not include a locking block. That was my oversight for not reading the description carefully. This kit is intended for Polymer80-style frames where the locking block is integrated into the front rail module.  If you're using DD19.2 or similar rails, you'll likely need to purchase a locking block separately.

Aside from that, I was very happy with the kit. The trigger group comes pre-assembled, which makes installation much quicker. It was essentially a matter of dropping the components into the frame, installing the pins, and moving on.
The parts fit well, everything functioned as expected, and I didn't have any issues with quality or tolerances. As long as you understand what platform this kit is intended for and don't expect a separate locking block, it's an excellent LPK that makes for a smooth, straightforward build.
