You'll have to Locktite the sleeve into place. I used blue 292 as that's what I had on hand. So far I haven't shot it so I don't know if what heat there is will loosen it or not.

But it can be a pain to set in there right. First time I tried it I had a large gap between the receivers and the gun wouldn't feed the Wolf 62gr HP's I had. Just a tap would send them into the chamber but most would hang up. I think M4 feed ramps would have solved the problem.

After I adjusted the sleeve I got a very close, tight fit. Fed great that way. So I took it out and Locktite'd the sleeve. When it dried I noticed the old wide gap. Crap....back to the drawing board.
