General
Leber V2, designed by S3igu2, is an MP5 lower housing adapted to carry an AR-15 milspec trigger. Download and print your own housing here if you know the process.
Competitors may simply download and print free files, but L2Prints goes further. As CAD designers, we bring a deeper understanding to the process, resulting in superior 3D prints even with identical materials. Our advantage lies in our expert precision, advanced equipment, proprietary pre/post-processing, optimized designs, rigorous quality control, and continuous innovation. We craft, not just print, for exceptional quality.
Leber v2 steel plates allow AR-15 trigger installation in MP5s. Serving as a trigger pack and buffer reinforcement, they replace standard parts and handle most stress, not the polymer housing.
The Leber V2 MP5 housing is a non-serialized part, so it can be shipped directly to your door; no FFL is required.

- Lightly tap the grip to loosen the detent bar, then push the cam to the semi position.
- Insert the flat end of a zip tie between the cam and the detent. Continue rotating the cam; it may take a few tries for the detent to loosen.
