So I was building like I dont know my 5th or 6th gun and i was like. Let's build a ar-10 this time around. Did some searching and it took me a while to find a combo that was in a good price range. Then I happen to come across Tom's Tactical and found the this 308. Ar10 BCG+ Charging handle. Had this combo for a while now and have shot 300 rounds and no issue. So a good price and performance for 308.. good buy and would recommend.


Awesome 308 bolt carrier group DPMS style AR-10 I built was having gas problems bought this bolt carrier group fix the problem


I bought this for a lr308 I am building. I am very impressed with the quality! The rifle shoots great . I will be buying another for my next build


This BCG went in a new Aero M5 build; worked flawlessly. All ammo feed, fired, and ejected with no errors. This build is also suppressed and dirtier due to increased blow back. Adjustable gas block tuned and brass fell about 2 feet away. Smooth nitride coating was very easy to clean, wiped right off. Will be getting another for next build, and all future builds.


PERFECT! Great Milling & Perfect finish! What a great price. Five stars times ten! I will be a repeat customer!
