If the bore is in the middle, not offset, I can do it.

Send me a PM so we can get this worked out.

I has some that have sat outside for at least 4 years without any problems. I paint them then shoot the paint off and leave them where they lay. I have had some laying on the ground for at least 2 years and are perfectly fine. Matter of fact AR500 doesn't seem to rust like mild steel. Even if it does get rusty just shoot the rust off.

Most .750" clamp on gas blocks will clamp down onto the barrel as long as it is spec at .740.

I have done exactly what you want to do. Get a clamp on, not setscrew, type gas block. Install a portion of a gas tube to hold the hand guard end cap in place. You might have to add a spacer between the barrel and hand guard end cap to keep it from rattling around.

As far as the heat I would not worry about it. The gas block won't be that much hotter than the barrel. It will be closer but unless you are doing mag dumps I would not worry about it.

When I installed mine I put the hand guards into the delta ring. The I pushed back on the gas block until it stopped then I clamped it in place. Again, I had to use something to take up the .010" difference between the .750" hand guard end cap and the .740" barrel.

If you click on the bullet to the left of the thread title it will take you to the newest post.
