Questions & Answers

is this upper 9mm compatible? Expert Answer

Yes, it would be compatible with 9mm.

by Tom B, Gear Expert, October 12, 2021

Does this upper need to be thermofit to the barrel?

Yes. JP Enterprises [via youtube] recommends a simple torch; put flame directly on threads for 7-9ish rotations to cover threads thoroughly. Other users say circular electric bbq starter placed on threads or set the upper in the oven at a few hundred degrees. Barrel might need to be put in the freezer for awhile to help as well. If more oomph is needed, finger-tighten a throwaway muzzle device on the end of the barrel, brace the muzzle with 2x4, and use a deadblow hammer to get it into the upper.
