Peening v. blue locktite vote here

[ebeeby]

What is the latest consensus on peening v. blue locktite to fix a loose gas cylinder (and hence sight) on a correct 1943 Garand? Let the voting begin.....

[Dan Shapiro]

Peen. A "correct" 43 probably will be shot very little if at all.

I use a high temp o ring between the gas cylinder and the hand guard this will tighten up the whole thing and improve your groups this method works for me

Ah! An interesting idea!

[PKelly]

Peen it. Blue Locktite won't hold and you'll be rinsing and repeating. Whether or not it's "correct" makes no difference anywhere other than the mind of the owner. Unless it's original as when it left the factory it's just a rebuild.

Peen the splines to tighten a loose gas cylinder. I can't for the life of me see how a "high-temp O-ring" would tighten a loose gas cylinder; keep the upper handguard from rattling, sure. (But isn't it supposed to be loose -- a little bit, anyway? Thas' what I was taught in ROTC in the 50's. [grin])

To the best of my knowledge, the use of the blue loctite on the gas cylinder will get you disqualified in an as issued only , non match conditioned rifle match/ i.e. a JC Garand match/CMP match.......peen it gently until she's snug, cheap & easy to do.....for a good gunsmith well versed in Garands...

An easy way to peen it is to use a socket from a socket wrench set. this will make the peening uniform. I don't like the O ring idea, because the front handguard should be a little loose.

[PKelly]

Ideally the front handgaurd should not be loose, this is a commonly misunderstood aspect of the rifles design. However, that doesn't mean it should contact the gas cylinder either. The upper hand gaurd should have clearance between itself and the gas cylinder, yet fit tightly into the upper band. This will prevent the gaurd from splitting and also minimize its contact with the barrel. A common feature of old match rifles was screwing the upper gaurd the the barrel band and removing the metal liner. The same effect can be achieved by glass bedding the gaurd into the band, but either method will render the rifle inelligible for certain matches. The easiest fix is to use a new barrel band that's still tight and will hold the upper gaurd securely. A loose upper gaurd will effect accuracy.

yet fit tightly into the upper band.-
You mean the lower band. I hate "upper and lower". Front hand guard, rear handguard is more descriptive.
