Most Helpful Positive Review Ultradyne or Cyberdyne?
This thing looks like it's from a post-apocalyptic future where mankind is at war with rouge artificial intelligence that has designed humanoid machines to exterminate the entire human species. I love a good old fashion A2 birdcage and this thing is that and then some. The counter locking nut makes timing a piece of cake. Stop wasting your time and buy it now.

Flash hider, my bottom.

Did nothing to help with hiding the flash. Very good looking and solid.

Excellent flash hider for a bit of extra length

by Pelt, Verified Owner from CO, United States Written on December 13, 2022
I went through 2 other flash hiders before finding this one. The A2 birdcage was too basic, the 3 prong didn't match my build so I got this and let me tell you, this is a very nice piece. Reduces muzzle flash significantly but let's be honest I bought it for aesthetics. It does add a good 2 or so inches to barrel length so it woupd benefit velocity for an AR pistol. All in all, it's a beautiful piece. It comes with a salt bath nitride finish and comes with the timing nut so it orients perfectly. This is a great buy and you wont regret the purchase.
Pros:
  • Nice finish
  • sleek look
  • added length to barrel
  • included timing nut
Cons:
  • you need two wrenches
Best Used for:
  • non-suppressed builds
Would recommend: Yes

Pretty sweet

by Nevertoomany895, Verified Owner from AZ, United States Written on January 16, 2022
So I was on the fence on whether or not to get this, and I'm mostly glad I did. Hider is well machined and very nice. The only thing keeping it from five stars in my case was the Ultradyne logo had some color loss, like the lasering was a blem. But went on nice, pretty slick with how the jam nut works. Only other gripe is it is not the standard 19mm brake wrench, slighty larger so had to dig for another wrench. But overall beautiful machining, longer than a standard A2 birdcage, does not come predrilled for a pin,but seems long enough to pin on a 14.5 if desired to get above 16".
Pros:
  • Nice machining
  • Slick three piece jam nut brake setup
  • Long enough to get over 16 on a 14.5 pin
Cons:
  • Ultradyne logo came mis-lasered, uneven color, like a blem
Best Used for:
  • Killin Terminators like the other dude said lol
  • Looking pretty bad a$$ while retaining the birdcage aesthetic
Would recommend: Yes
