The gas block is an important part of your Ar15 to ensure proper function.  Don’t waste your time on a cheapo out of spec gas block, and don’t overpay for a decent one.  This is what you need if you’re serious about building reliable ar15s. 

These gas blocks are hands down the best we have ever used.  This is our preferred choice for builds as the fit,finish,price,quality and ease of install can’t be beat. The finish is amazing and installing the gas tube and roll pin is painless.  After dealing with inferior gas blocks, we were glad to get these made to suit a builder’s needs.  Once you try these gas blocks, you will fall in love.  You will exclaim “WHERE HAVE YOU BEEN ALL MY LIFE!?!?!?!???” and you’ll never want a different gas block again.
