Huge Disappointment

by Claytonian, Gear Expert from KS, United States Written on May 9, 2024
I bought a few of these because they were a good deal. I just tried to install one and what a piece of junk. Either the threads are off or it's bent because it come out of the lower at an upper angle so the BCG/Buffer grind when charging it back. I uninstalled and put in another buffer tube I had on hand and no issue. It's a very visible upper angle, something isn't right. Be careful.
Most Helpful Negative Review It works but....
This part works. Dimensions are within spec, and my buffer weighed 3.1oz, so no issues there. The finish on the one I have is nothing to write home about. In fact I have bought blemished parts with better finish than this one. The anodizing on the tube is uneven and splotchy, and the castle nut looks as if it was cold blued by a 3rd grader! Luckily the tube is going under a fixed stock. And I will have to re finish the castle nut before install. Buyer beware.

Excellent product with no problems at all. Fit,finish,quality was excellent in all areas and works perfectly. Used it on a Noreen billet lower to build a .223 bull barrel target rifle. Would recommend the product to anyone.
