FAQ
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.
Our current lead time is 2-4 days. L2Prints prioritizes exceptional quality. Unlike competitors who may expedite production, we meticulously prepare our materials with a 10-hour drying process at 200°F before commencing a precise 20-hour print, followed by a critical 10-hour annealing phase at 190°F.
You will need:
- Leber V2 housing
- Super safety (cam, detent and level) and AR-15 milspec pre-cut trigger
- MP5 slip trip
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.
Troubleshooting
To unstuck your detent, follow these steps:
- Cock the hammer and remove the detent screw located at the bottom.
- 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.
Yes, we offer free SS fitting! Here's how it works:
- Place your housing order. Then, simply chat with us or email info@L2prints.com.
- Send us your SS Kit (detent, cam, lever, detent spring), mil-spec FCG (pre-cut trigger, hammer, disconnector, and springs), and ejector. (Need an ejector cut? We can do that for an extra $20, or you can order a pre-cut one from us.)
- We'll fit everything to your new housing and send it all back to you.
