Most Helpful Positive Review Great product
Decent shipping. Looks like great quality. Will be building the 300 over the next couple of weeks, so I look forward to shooting it. I purchased this product because of the brand and it was a great price and AVAILABLE. Thanks Optics Planet.

50 yards groups 2" at best

by Diesel from Michigan, Verified Owner from MI, United States Written on May 15, 2025
Well feels and looks great good build but 50 yards accuracy of bench with sand bags wasn't that good, at best I get 2" groups which I'm not really happy with that, shooting 220g stealth ammo subsonic with Hyperion suppressor. With 16" PSA barrel I had better results at 100 yards. Overall it's good built feels great. Didn't give it 5 starts because of groups but if you are running red dot on it it's more then enough.

Perfect length

by Big E, Verified Owner from MT, United States Written on February 27, 2025
Was looking for a 10” barrel to go with a 9” handguard and this was exactly what I needed. Can’t go wrong with ballistic advantage, great performance right out of the bag. Had no problem stacking rounds on top of each other at 50yards.

Barrel for Spare Parts Build

by PerfExSI, Verified Owner from NJ, United States Written on January 25, 2025
I’ve used Ballistic Advantage barrels before and went with a 14.5 inch 300 Blk for a spare parts build. Muzzle brake was just pinned and welded at my gunsmith and the upper looks really nice. Waiting on the lower and then I will give it a go at the range. Price was excellent and I trust BA barrels which is why I bought it. Only reason I give it 4 stars is that I have yet to shoot it. Once I do, I may give it the extra star.

best 300 barrels

by steel, from GA, United States Written on March 9, 2024
BA is making the highest quality steel nitrided 300 blackout barrels around, and they offer one in every size to get your perfect build. The modern series profile is perfect for high durability and accuracy, without any unnecessary weight. Between the high quality Barrel and low burn 300blk cartage, I expect these barrels to last a very long time. BA is an excellent company with great customer service. I’ll recommend these barrels to anyone interested in 300 blackout
Pros:
  • value
  • Price
  • Durability
  • Quality
  • acurate
Cons:
  • None
