4.0 Rating Outstanding AR - 1/23/2015
Reviewer: Kev
The only issue I had was that I had to replace the gas rings. $1.30 later it was fixed, other than that one issue, I have had this rifle for almost a year now, shooting monthly and had no issues shooting various types of 5.56, .223, including once fired brass. Being active military, this was the closest, and cheapest base rifle I can find that would suit my needs.
