Once you can get the old cap off the hw silencer, mine had loctite on it. The new end cap screws in perfectly and snugs up tight against the silencer body. No interference with the standard internals. Perfect to make it flat faced. Would I buy again yes, will I need to doubt it as it’s excellent quality and will probably see me out.

These are really excellent and work really well especially with rifles that have a shroud.
