Installed this in a week ago. Ran only 300 rounds so far. Didn't have any issues with it at all.
I bought 2. Paid a few extra bucks to have them pre-built. This is the worst part of assembly…for me. They did great work and took great care in packaging them both. Excellent value and saved me a little time.
Install was very easy, have not to my rifle to range yet. That will next i give update on that
Breek has been my "go to" for their gas blocks and tubes for a while now. The fact they offer them assembled is really cool! Great price and quality.
Nice fit and finish can’t wait to finish up the uppers. Breeks rocks
Pre-assembled gas block and tube lined up perfectly and was very simple to install. I will definitely buy again for my next build!
