screw holes strip real easy.

This is made of aluminum. The threads strip very easy.

Ok for now

I have installed it on my AR and it works. One of the draw backs is that I feel the housing is made out of a too soft aluminum. I am wondering how the gas port hole is going to hold up with this soft aluminum. I also stripped some threads installing one of the rails. I was using a torque wrench set at 15 in lbs to do this. I helicoiled the screw hole and everything is fine. I think all the screw holes should be helicoiled. Other than that, I think this is a good product.

With your eyes closed!!

It's easy to install the gas block but it was not easy to remove the old gas block with front sight housing. On the video was it easy but it was'nt. The old gastube is broken bij removing. No trouble with the screws, little more than hand tight

Good but not great

This gas block slid forward on the barrel of my duty rifle under use. Like another reviewer noted, the threads on one of the rails stripped out. Brownell's outstanding service prevailed and they shipped a new part with no questions asked. If the set screws fail to hold the block in place again, however, I will return the part for good. It is held in place with only three set screws. I would have used more set screws if I had been the designer.

Good but not great

Good design, good idea, but the metal is cheap...it'll do the job, just don't try and tighten the screws for the extra rails on very tightly...the metal screws stripped with just a little bit of tightening...If I had known that they were cheaply made I would have gone with a different gas block, but hind-sight is 50/50...
