The Leber V2 is an AR-15 Fire Control Group (FCG) trigger pack compatible with MP5 and MP5K firearms. It uses a steel "cassette-style" housing to hold the FCG and Safety, and a steel insert to reinforce the rear trunnion.
The steel plates interface with the receiver at the front and back, removing all stress from the polymer external housing. These steel plates allow for a flush external plymer housing, giving the Leber V2 a more factory HK trigger pack appearance while also being much stronger. The lower also features a built-in grip to mirror the factory HK trigger pack, which significantly improves durability.
Credit for the design goes to S3giu2 and his development team.
All housings will come with the reinforcement plates and mounting hardware included. Any additional parts that are selected will be installed in the lower.
