If anyone can provide a link to the above subject it would be appreciated.  I found this issue on Quarterbore that was written by an AR15.com member "Compuvette".

I have his problem with the installation and would like to see what he did to solve it, as I really do not want to sell the M5.  If anyone can help with this matter it would be appreciated.

Thanks,

Mike

That says he used a dremel on the gas block.

Not the gas block, but the RAS itself.

still awaiting any help that can be provided, the Quarterbore article is extremely slim on details.  Anyone?

I would ink up the gas block, install the RAS, then see where the ink contacts the inner surface of the RAS. I would then shave down the gas block to relieve these contact points. It'll be a lot easier to sell your M5 later if it isn't cut up.

Or, you can just get a low profile gas block from Larue Tactical, PRI, Vltor, etc. The hardest part of replacing the gas block is removing the taper pins on the front sight assembly, but if you have the right punch and some scrap wood to support the barrel it takes all of 10 minutes.

Don't mess with the M5. Either try to trim down the Gas Block more or Get a New Low Profile one.

Thanks guys for the advice.  I looked at the M5 again and there is no way to trim the HG itself without compromising the integrity of the frame.  I guess it is dremel time.
Thanks again
