    Outstanding performance

    Posted by Jeff S. on Sep 23rd 2025

    I've had this barrel installed for almost a couple years now and have really put it through the paces. It has cycled everything from hot 110gr supers to 220 gr. subs downloaded to 880 fps during load development. I haven't tried those 880 fps loads unsuppressed, but it has cycled all other ammo both with and without the can. Suppressor being used is a DeadAir Sandman S and a heavy weight buffer. I have literally never had a malfunction in this rifle and I have to give a nod to this barrel for being a big part of that. It seems to be just gassed perfectly. Standard BCM fixed gas block, so no tuning necessary. I am fully planning on building another with the same exact barrel, I've been that impressed with it.

    8” .300 BLK Excellent Value-Even Better Accuracy

    Posted by Al on May 23rd 2025

    First Wilson Combat product I’ve purchased. The fit and finish of this barrel are outstanding. It looks good. It feels good. Once you take it to the range - you’ll see how it really shines. The accuracy is incredible. Anyone who’ve I let shoot it comments on the accuracy. That’s with both subs and supers. I shoot this barrel suppressed 100% of the time with H3 buffer and Sprinco white. After 500 rounds - I’ve had 0 malfunctions. Highly recommend.

    Extremely Accurate

    Posted by Edward Elias on Dec 27th 2022

    Just built a new 300 upper for Christmas and was surprised how accurate this pistol length barrel is. I’m thinking about ordering another. A+ thanks Wilson Combat.

    Flawless

    Posted by Sim on Jul 31st 2019

    First Pistol build and first ever using Wilson’s products. The fit and finish is amazing. I paired the barrel with their Low-Mass BCG. The two worked in perfect harmony. No cycle issues, ate it up and spit it out. I finally was able to make it to the range today and was just amazed. Glad I went with this set up.

    Blown Away

    Posted by Brice on Apr 7th 2018

    I put the 8in 300blk in a pistol build soon to be sbr suppressed. Unsuppressed shooting hornady American gunner 125gr hpbt, I was able to shoot 1in groups at ~105 yards from a rest with a scope for testing. There was about a 3-5in drop from 50 to 100 yards but consistent 1in groups at 100 yards! my 16 wilson 556 barrel wont do that as consistently so Im over here scratching my head, very impressed and blown away.

    Excellent Sbr/Pistol Barrel

    Posted by Ben Isaacson on Jan 15th 2018

    Purchased this 8 300 Blackout barrel for a suppressed AR15 pistol build. I had Wilson add the Grey Tuff Armor cerakote. The barrel looks and shoots phenomenal. High quality was easy to find in the finish, fit to the receiver, rifling, threads, logo, feed ramps, and range accuracy. I was impressed to receive the barrel in such a timely manner even with cerakote being added and shipping over the holidays. Not to mention, picked it up during the end of year sale for about $50 off. Will happily buy another Wilson barrel for my next project 6mm AR.
