Trigger group will not install on MP5 or G3. Trigger pack works great installed on any of 4 different HK and PTR housings but forces down 1/8" at front as supplied. Housing is fitted on all my chassis but will not fit with any of my trigger packs installed. I HAVE WORKED ON IT AND WILL PROBABLY FIGURE IT OUT BUT SHOULDN'T HAVE TO SPEND 3-4 HOURS ON THIS ISSUE.
