It's built well. I was able to specify which buffer weight I needed. I kind of guessed. The "H". 3.8 oz works well with my M4 and 55 gr. Wish I could've specified the qd connect end plate.
I learned that this Mil-spec tube is a a key structural part of an AR. Worth buying this quality. It came really quickly.
Fits as is should smooth swap
Great product and great service. I’ll be back. 😊
