Most Helpful Positive Review Exceptional quality
I was looking for a small light weight blast shield to pair with my AR9. There arent a lot of reviews out there so I thought I'd give Breek Arms a try. I purchased the shield with a 9mm flash hider and was very pleased with the quality and finish of both. Installed easily and did a great job of pushing the blast and gases forward on my 11" AR9. I was so pleased by the results, I purchased another flash hider to put on a 10.5" 5.56 barrel.

Outstanding value

by Centauro97, Verified Owner from VA, United States Written on March 31, 2024
For the price, it's an outstanding value. Less than half the cost of some of the other brands, with no difference in function that I can tell. Nobody shooting beside me is complaining about the covered brake I'm using.

Castle blast shield

by N, from CO, United States Written on March 6, 2024
Works as advertised, threaded right on. Really tamed a 10.5 that was a little bit absurd in its concussion. Amazing price point, the surefire 3 prong/warden combo is unreasonable priced, this fills that niche' at a price that isn't hard to swallow.
Pros:
  • Price
  • install easily
  • Looks & fits good
Cons:
  • None especially at price point
Best Used for:
  • Budget AR set up
Would recommend: Yes

Solid Equipment

by AD, from TX, United States Written on December 13, 2023
This item arrived on time and is exactly as advertised. Quality material and a solid-performing muzzle device. It is nice to see the smaller guys come through in a big way without demolishing the wallet.
