[funeral_tripod]

Does anybody have any ideas how i could make the hole bigger? or if i can geta thinner gas tube? oreven if i can get a grip/ris that doesnt need gas tube to fit on snugly

File it or drill it.

As above, just drill a larger hole for it.

But i would recommend you drill a hole in something else first, like a a block of aluminium and then try and fit the gas tube into it, else if you drill it too big in your gun then you will have the opposite problem, simples.

Re: m4 gas tube

Just compare your gas tube to the size of the drill bit. Find the one the same size then go up .5mm, or 1mm if you dont have ones that go up in .5mm.

I wouldn't worry too much if you make the hole slightly too large. Even if it's a couple of mil to big, the movement will still be tiny and the gas tube's not a load bearing part anyway.

It's not worth going out and buying exactly the right sized bit, but then again, try to get it as tight as you can. Worst case scenario, it wobbles a bit and you have to put a drop of epoxy in there.
