5 of 5 Great Product August 17, 2020
Reviewer: Michael Heinze from West Point, UT United States  
Just received my BCG and it looks great. I haven't had a chance to shoot my AR since installing it, but after inspecting and installing the product I do not anticipate any problems.

5 of 5 Impeccable Workmanship! August 17, 2019
Reviewer: Dennis from Tampa, FL  
I was very pleased to see the high quality of workmanship and finish of the AR-15 5.56 Nickel Boron BCG. It slid very smoothly into my 80's Colt Delta HBAR. It cycles very smoothly when I manually manipulate the action. I am looking forward to seeing how it performs at the range. Initial impressions are quite impressive!
