Gas block installed, free float quad rail as well and my S&W M&P 15 Sport II looks and shoots perfect. Mounting a SightMark 3-9x42 scope next. Can't wait to dial it out to 200+ yards.

These do not have to be fancy. It only serves to hold the gas tube. Many companies make these so complicated and fancy that they lose their real purpose. Buy this if you want a simple gas block that is well made and works!

I have assembled many gas blocks and attached them to many barrels, this one was no different other than the price. It was a low cost and shipped quickly. I would purchase another gas block (if I needed one) and probably more goods from AT3 Tactical, just because the order was filled quick and shipped even quicker.
