Another thing about having the 'prongs' of the gas regulator circlip at the top, exposed is that you can bet, just as sure as god made little green apples and as night follows day that one of the more 'learned' crunchies WILL unhook it with the small blade of the combination tool and it'll disappear under the handguards, deep into the bowels of the gas cylinder. Then he'll unscrew the handguard screw and take off the handguards and THEN, he'll have access to the gas cylinder that is, according to him, a bit loose because it has a small degree of rotation built in. So the next thing is he'll blame that on his pi55-poor scores that morning and try to tighten it up against the small PIN, gas cylinder that he hasn't noticed under the gas regulator.

No small pin to use as a tommy bar to tighten the gas cylinder............ Not even a problem. In his belt he has tucked his leatherman tool. And so it goes on and on and on.

Don't laugh, it actually happens and we used to see it time and time again. There would be two outcomes to this. The first would be that when it's totally all come unstuck, it'd be put back into the armoury like this or the second scenario would be that he'd walk over to the Armourers shop and say words to the effect '...... sod-all to do with me..... I got it like this!

Is it still like this today Skippy, Son? Arte et Marte
