VG6 Epsilon


I shot the Epsilon last Wednesday, for the first time, at a skills and drill class for carbine and pistol. The device helped greatly with my follow up shots in both accuracy and speed. From my perspective the muzzle flash was equivalent to the A2 birdcage, but I don't have pictures to prove it.Primary Arms came through with a great low prices and fast shipping. I'm very happy with the device and purchase.

Dragon Slayer


In a word; AMAZING! The muzzle stayed completely flat and there was only the very tiniest amount of recoil. The only noticeable movement was the buffer and bolt movement. The only downside is the pretty significant side blast/concussion. My good friend has a lantac and the Epsilon is as good or better, though I think it isn't quite as loud, but the pressure wave is a tangible thump in the chest.Overall, friggin awesome comp for a good bit less than a Dragon.



VG6 Epsilon does everything I expected and then some. Performs flawlessly. Price can't be beaten. Primary Arms is, as always, a pleasure to deal with. Quick shipping, great products.



amazing break using this on a DTI lower Anderson upper with a 16 inch barrel. After the first 5 rounds i could tell a difference. Feels like a whole new weapon. .25 barrel rise at most although the concussion is felt in your chest might be a deal breaker if going to a busy range. Super fast shipping will be buying a lot more from here in the future.

Best muzzle device I’ve ever used

by -

The VG6 muzzle products are in a league of their own IMHO. They look just as great as the function and they function beautifully and they are priced very well, especially when on sale. I used the Epsilon on my last two builds and I’m so glad I did!!

Perfect match for my Indian Creek Blast Forward Device!

Fit & finish excellent.
<br>Installation & timing was a breeze.
<br>Fits underneath the Indian Creek Design 1/2" MBFD (SKU: ICD-BFD12TP) like it was made for it.

Best Break/Comp

by -

Amazing break/comp. Put this on an AR pistol build. I get 0 muzzle rise with this. It does scare the life out of everyone within 20 feet of me when shooting it. The shock wave is pretty intense. I don't mind, but I'm not in the path of it.


by -

These are on all of my AR's. Simply outstanding, just like everything VG6/Aero Presicion/Ballistic Advantage

Keeps you solidly on target. Don't hesitate just get one.

The first thing I noticed at the range was the lack of muzzle rise. Stays on target reliably. Another guy at the range commented on the concussion and noise but I did not notice it from behind a full size 16" rifle, doubled down on hearing protection. Quality looked good, clean install. Would buy again.

Reduces recoil significantly and looks great

Night and Day difference

by -

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

by -

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

by -

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

by -

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.
