Leber V2
AR15 FCG (Fire Control Group) based SP5 / SP5K Lower
--------Leber V2 Description--------
The Leber V2 is a AR15 fire control group lower for the MP5 and MP5K.
It uses Steel plates for retaining the FCG with all other critical points
benefiting from the steel plates. It was designed from the ground up to
be super safe compatible and to function in combination with the
Slip Trip V2. Credit to @UberPoor on X/Odysee for the ARMP5 V1 & V2
as this was heavily based off those early designs.
For those interested in supporting future projects, donations are greatly appreciated.
