CMC low profile gas block fits perfectly underneath my hand guard. Everything works as it should. No problems so far.

i have 2 of these gas block and there tolerance where the gas tube goes in to the gas block is horrible. these gas blocks get a lot of blow by causing shot strokes. CMC needs to tolerance check the gas block.

Used this gas block on my Criterion "Hybrid Profile" barrel. Fit and finish were perfect! A quality piece of equipment. Absolutely no gas leaks.

As I stated in the title, this gas block's fit and finish is great. It's made of 17-4PH steel which is an astoundingly strong steel, one of the strongest probably on the market. It's a much better steel than say the BCM gas block… but the BCM is a much better gas block in that the tolerances are much better. On this CMC gas block it's very loose on a .750 barrel AND the inlet for the gas tube is also very loose. I was disappointed in that fact, though overall it functions fine. So all in all, you really can't get a better material or fit and finish for a gas block but you can get better tolerances. I can not say whether or not I got a bad batch or if they're all that way, but my sample size is 2 and they both are the same. If you can deal with loose tolerances you can't get a gas block with better steel than the CMC.
