– S3igu2 – Is the creator of this housing. ALL credit goes to him!
All housings are made to order and printed in Pa612-CF. A Nylon carbon fiber blend.
IF YOU HAVE A AP5/AP5K PLEASE CHECK YOUR DENIALS! NEW PRODUCTIONS HAVE DENIALS THAT WILL CAUSE FITMENT ISSUES WITH THE LEBER LOWER.
A Slip Trip is Needed for this to run Super Safe!
A small cut needs to be made to the ejector for fitment. I include the jig so there is no guess work!
The Leber V2 is an AR-15 Fire Control Group (FCG) trigger pack compatible with SP5, SP5K,
AP5, and AP5-P. It uses bent sheet metal to retain the hammer, trigger, selector, and ejector.
The steel plates interface with the receiver at the front and back, removing all stress from the
polymer external housing. The Leber V2 was designed from the ground up
to work with the super safety, though its usage is optional.- s3igu2

This kit works great. Please note that you will need an
AR-15 fcg
Super safety
Mp5 ejector
ejector spring
and slip trip
To make this fully plug and play. Installation was pretty simple and the slip trip may need slight modification to clear the denial block without resistance. Great customer service.
