I believe when I bought Gunslick when first came out there were such thinks as bore guides yet. Woulda been nice to put the cart before the horse.
Bore guides been around a long time. Main purpose is to keep your cleaning rod from rubbing the bore and wearing it out prematurely. Really good idea to use the bore guide even if you don't use foam. Here's one brand:
DEWEY BORE GUIDES
I have used the foam in AR's and M1 Garand w/no problems but have switched to other products after acquiring a bore scope.
When foam used, first be sure the gas port is above the bore (the Garand must be upside down because gas port on bottom of barrel). This helps keep foam out of gas system. With the Garand, I removed gas plug so that I can see if any foam got into cylinder and have yet to have any foam pass through the port. The AR port is on top of barrel and you can't see if foam enters tube, but I rather doubt that it does....any rate, one shot of Carb or brake cleaner will push it out into the bore. If you want to give it a blast of compressed air for good measure, have at it; then I like to put a coat of oil in my bore in spite of the fact that the foam mfgrs. say the foam is a preservative...just old school, I guess.
I really think the warning of "foam" getting into the gas cylinder is a CYA move. I suspect that the foam will take the path of least resistance as it expands and that is out the muzzle of the rifle (.20" or greater dia.) as opposed to passing through a hole no bigger than .02"-.05". I think the real danger is if/when the gas port is below the bore, and the foam returns to the liquid state, as it does with time, it simply runs down into gas system, but that is JMHO.

dultimate should read that twice. ^^^^^
never had any trouble with foam gluing things together. then again, i don't spray it in and set it in a corner until hunting season rolls around next fall.

who in the world would do that? gotta use your brain a little bit with some of this stuff.
