V Seven Weapon Systems 300BLK AR-15 Barrel - 6.5"

Rainier Arms was one of the few places that had this in stock for a reasonable price. They also shipped it quickly (ordered Monday, chose a standard shipping option, and got it Friday).

The barrel itself is excellent, and the pinning/dimpling reliefs make gas block installation a breeze. I will say that I had a hell of a time installing t...Read MoreRead more about Rainier Arms was one of the few places

he gas block roll pin so just make sure you have a decent starter punch somewhere in your inventory.

In terms of shooting I haven’t had any issues with subsonic stabilization, which I was worried about given the 6.5” length and 1:7 twist (I just wish they had gone with a 1:5). Also, it functioned flawlessly with subsonics/suppressor and unsuppressed with supersonic ammo and a Dead Foot Arms 2.5” PDW/SCW brace. If you’re worried about cycling issues with a PDW style brace or stock, this barrel and gas block combo should perform admirably. Read LessRead less about Rainier Arms was one of the few places

Great quality and great service

This V-Seven barrel is the same excellent quality as all the other V-Seven products I have bought. Fit and finish are outstanding. No issues installing and shot like a dream (with suppressor). The heritage/origin of the V-Seven team definitely shows.

This was a very quality barrel ...Read MoreRead more about I was a little skeptical of V Seven

After having run this barrel for almost a year, I can firmly say that this is a sweet 300 blackout barrel.

I've only shot 110 grain hand loads through this barrel but being able to a solid MOA out of a 6.5" barrel is impressive to me. Granted I've never taken it further out, but I never intended for this barrel to be on a rifle to really ...Read MoreRead more about After having run this barrel for

shoot long distance. So the fact that I can get an MOA out of such a short barrel amazed me.

Overall I couldn't be happier with the barrel. The fit and finish are superb as well. Read LessRead less about After having run this barrel for
