Tactical Kinetics 300 blackout

Barrel Review

Have you ever had something so long that you end up going down a deep hole of what you want to do with it? Well I did with this barrel. I had it on the shelf, looked at it, and wanted to do so many things with it that it soon became a thorn in my side. Now this thorn is me, not the barrel. The Tactical Kinetics 300 blackout barrel is fantastic. It is well machined and looks better than some of the big name rifle makers barrels. Tactical Kinetics sent me this barrel for review almost a year ago. No excuses but life happened and that's why it has taken so long to do this review.

I mounted the barrel in a no name, unbranded, upper and put it on a PSA lower that has a Sylvan folding adapter. Fitment of the Tactical Kinetics barrel was plain and simple: great machining, the coating in the barrel looked good, and the threads for the barrel nut were properly machined. I ended up taking it apart three times, changing out gas tubes, gas block, and finally going with an adjustable gas block from Velocity Precision.

After completing the first build, it ate everything I fed into it when I was firing for reliability. Except for the subsonic 220 grain ammo I had for testing. I knew this was either a gas issue or a buffer weight issue. So back to the drawing board. Build two was now completed and the Tactical Kinetics barrelled upper was placed on a SBR lower. In a bout of frustration, it still would not run my subsonic ammo. So for the third and final time, I reassembled all the same parts. The rifle worked with all my ammo now. What a relief. Then I realized everything I had done, when I put all the parts together, was my fault. We won't go into that now.

At the range, I took the little 8.5” barrel out and sighted it in at 25 yards. It fired all different weights of ammo. The barrel grouped best with 204 grain subsonics with a suppressor attached to it. I only had a red dot on top and was shooting from a rolled up jacket. Then I went to dumping magazine after magazine through it to see what it would do when it was hot. Well there was not a lot of shift in impact, maybe 1” and that was probably me. The accuracy was far better than a Bear Creek upper that I have with the same length barrel. Groups off the rolled up jacket were about 2.5 inches. For me and my intended use of this rifle, I thought it was great.

This is my first barrel review and it has been hard to do. What I can say about the Tactical Kinetics barrel is that the machining is quality, the rifling was good, and it grouped well. I know comparing it to a BCA upper is not fair, but that is all I had.

Would I recommend this company to buy from? Damn skippy I do. I already have a wish list going for a few 6.5 Grendel barrels they offer. Tactical Kinetics is one of the company’s you want to do business with. Quality parts, great customer service, and patience for not sending headhunters out for the review.
