Night and Day difference

Makes the entire gun shoot different, shots feel so much smoother, the noise and blast might be an issue for some indoor range shooters, but definitely worth every penny. I would buy this again even if it was more

Freakin Awesome!


I have this brake on one of my AR pistols with a 10.5" barrel. I love it! Totally reduces muzzle rise, but yes, it is a little loud. It looks cool too. The sale price makes it even better. Get it! I have the Gamma on another AR. Another great brake

Function is Fantastic.


Function is amazing. Drastically reduces recoil and muzzle rise...Put this on a 12 inch side charging upper and the gas had nowhere to go but forward..was like shooting a 22. NO rise, easy follow up shots and faster shooting on target. Ultimately dumped the side charging upper. Put a regular upper and a gas busting charging handle. Not quit as good, but still pretty friggin awesome with recoil and little rise. Bought the gamma too. Catch em on sale, these are a no brainer. I'd recommend to anyone.

Buttery smooth recoil

Nice finish, aesthetically pleasing, functions as advertised, awesome price. You may need a shim kit. I've used 2 of these on ballistic advantage barrels and one timed perfectly but the other was a full 180° off.

VG6 Precision Epsilon Compensator


Practically eliminates recoil and barrel rise. Greatly improves follow up shots. Did not notice any additional noise or concussion. Great price and speedy shipping from Primary Arms!

Bad to the Bone

This muzzle compensator is great works really well on my 10.5 upper bought it on sale and would have payed the regular price it's that good .

Better Than The Rest

I had originally ordered the VG6 Gamma, but then read about this one and wanted something to control flash for night shooting, and also because why not, so I gave this a whirl. I've tried the Surefire Warcomp, and the VG6 Gamma on a friend's build, and I'm just so happy with this brake/compensator/hider.
<br>Rock solid, whatever recoil or sway my 16" mid-length 556 had before doesn't exist now, super fast target reacquisition and paired with the CAGE device, I'm not making any enemies at the range.
<br>As usual, best price found on PA, and they shipped it to me super fast.



It arrive really fast . It didn’t take long at all . I just try it at the gun range .. I can’t believe how amazing! It works .. I love it . Thank you primary arms . 🙏

No Jump or Recoil Left

5.56 isn't exactly known for recoil but the epsilon removes every last little bit of it. If you want to shoot flat this is definitely for you. Would recommend for competition shooting as it keeps you flat and has less flash than you would think. It goes without saying, but the epsilon is very, very loud and has quite a bit of concussion if you are standing to the side of the shooter. Would not recommend for a defensive rifle/pistol, but would recommend for competition, fun, target, or hunting.
