modifying forgrip?

[Predater]

my rt pro has a non gasthrough forgrip. but the bottom is taped for a fitting. can i drill up and tap the side of the forgrip at the top.

i am wanting to now if the aluminum is strong enough to hold 900psi.

The most i've seen done with the RT Pro grip was a hole drilled thru it and macroline was used. For my own RT Pro I found a used RT grip with the gas thru in it. They are hard to find used but you can get one from AGD if you call them. I think they are $35-$45.

Fore-grip

You can drill a hole through your RT Pro fore-grip. The aluminum is plenty strong enough. You don't need to drill a large hole, 1/8" or 3/16" will do. The thread size for the fitting is 1/8" pipe! You'll need a fairly long drill bit and you should use a drill press for the job, but it can be done. Good luck

i use a drill press any time i can over a drill. so much easier. a 6 in bit will be long enough. when its done ill post a pick.
