    First off….top notch product, I have about 60 rounds out of this 12.3 barrel and getting sub MOA now, can’t wait till it’s fully broken in…… I have a carbine class in a few months and cant wait to see how it performs….Second B King’s is my go to for most of my AR needs, great pricing and service….. Highly recommend first looking here before purchasing from anywhere else

    B King’s was recommended to me by a friend and I have to thank him. I was looking for a BA 12.3 Hanson barrel and King’s had the best price I could find by far. I ordered it on a Tuesday and it arrived at my door on Saturday. It was packaged well to protect it through the shipping process. When I unwrapped the barrel it seemed almost too good to be true to get a barrel this nice for what I paid, especially since it came with a pinned low profile gas block. I ordered the carbine length melonite gas tube for it. With shipping, insurance and signature required fee the order came to $129 altogether. I highly recommend that King’s is the place to go for AR build components based on my experience and their good reputation. I know I will be back to get what I need for the rest of this build. Thank you King’s!

    The same quality B.A. barrels that are sold every where, but at a much better price with extremely quick shipping. Had such a good deal I ended up picking up barrels for 6 builds.

    Paired with a 2A Palouse-Lite Upper & a 11″ BKF Mod-1 MLOK rail. Barrel is reasonably heavy profile ‘gunner+’ style but not overkill. I usually prefer ultra-lite or pencil barrels but the handling and balance is excellent. The balance point is in the middle the magazine without a an optic or rear iron. Once those are added, it should be perfect.

    Ordered 2 of the same barrel, received one. Notified the team at BKF and they fixed it immediately and shipped me the second promptly. Pretty happy with the 12.3″ barrel. Its everything I wanted from the AR platform in 5.56. I took both to the range right away after install and they feel great. I did not chrono them or put a large round count through them yet – but I did enough to feel confident within 200 yards. The pinned gas block is a nice feature and inspires confidence. Would buy from BKF again.

    Awesome barrel from an even more awesome company! Shipping was fast and arrived in packaging that kept it safe and secure. B. King’s firearms couldn’t have made this purchase more streamlined and helpful. Great company to work with. I have already recommended them to multiple friends. I couldn’t believe how low the price was compared to other suppliers! I will defenitley be using B. King’s for future purchases!

    Also for reference, I matched this barrel with a Toolcraft BCG coated in DLC and it headspaced just fine. Ran an H2 buffer(~4.7oz) and spring from Aero precision and had a perect ejection pattern.
