great comp!

by -

next to no muzzle rise and no perceivable recoil. But the more effective a comp is the louder it is!
<br>I used to think my AK74 comp on my wasr10 was loud this is way louder.
<br>for this price you get a lot of awesomeness. fit and finish excellent, performance excellent. it also isn't super bulky and only adds 1.5" to muzzle, low profile with no jagged edges so it will be snag free.

Love it but it is rediculously loud.

The barrel doesn't move. Gun shoots like a laser. LOUD. Holy Mother it is loud. I shot my 10 inch barrel 300blk with regular A2 before I shot this. I thought it was loud. I took 2 shots with this on a 18 inch barrel 223 wyld and had to stop. There was a guy in his truck watching us shoot. I never met him before and he was there just watching. He brought me some hearing protection. Asked if it was a 308. Point is, it preforms outstanding. Put something over your ears before you shoot with it. I Highly recommend this product. Performs incredible. Just really loud.

For the money (or even a lot more) it's awesome.

For the money and mixed purpose, this is probably as good as it gets... as I see it as 50% less recoil, 35% less muzzle rise, 15% LOUDER. From what I've been seeing vs an A2 FH it knocks recoil into a non-issue and the muzzle doesn't move nearly as much. That said, with most any muzzle device change, as far as LOUD/BLAST: outdoors it's really not much louder than an A2 Flash Hider and doesn't seem to bother anybody (even shooters next to me), Indoors, ...well you might not make friends with the shooter next to you LOL!

It’s cheap & works great, get it already

Completely agree with Raymond’s review. Decided to try this due to good reviews & EXTREMELY inexpensive price, especially if you get it when on sale. It’s a great brake for any price. Very comparable performance to Lantac Dragon or VG6 Epsilon as far as reduction of recoil & muzzle rise, but I think it has slightly less aggressive side blast concussion. It’s definitely noticeable concussion, just didn’t seem as bad as the Lantac. Haven’t done my own personal scientific side-by-side testing, but it may actually outperform the two aforementioned more expensive brakes. If you want less recoil & muzzle rise & can deal with the side blast then the Jcomp is by far the best bang for your buck. Pull the trigger, you won’t regret it.

Badass comp

I've usually fired ar15s with the old style bird cage so this was my first true compensator. With this installed my rifle has even less recoil. Of course it's loud and has a pretty crazy blast, but I'm more than ok with that. Great job SI!

Best Deal for Muzzle Devices

The JComp has similar data to the Lantac Dragon in famous muzzle brake shootouts. In addition to that, it is about 25% better in flash reduction according to famous flash hider shootouts. I got my Dragon on sale for $80... I got the JComp for $25. It performs as well as my Dragon with less concussion and noise, too. Can't go wrong!!
