I have been playing with my son's NEA 10.5" and 7.5" carbines. One of the first things I discovered was the muzzle blast. I was going to fire a single shot through each of them through a Chrony to see how much velocity was lost over the 14.5" barrel I usually shoot.

I fired one shot and the blast was painful. You may know the sharp pain and ringing sensation that tells you to stop if you don't want to do a lot of permanent damage.

Then I started trying out different muzzle devices. They made the blast even worse for the guy beside me.

Severl posters here suggested I try the S&J Linear compensator. I had (have) no idea what a "linear compensator" is, but today I tried one. I probably flinched when I touched it off, but the noise was dramatically reduced. No blast. No pain.

The device has 6 ports on the front, but no ports on the side. All the blast is projected forward. The result is a big reduction in noise to the shooter. The marks on the side are deep dimples (weight reduction, I assume).

One of the nice features of this layout is that there is no "UP" or "SIDE", so there is no indexing. Just screw it on and be done with it.

If you have a short barreled carbine and muzzle blast is an issue, this gizmo works. According to the S & J website, they have several models of this. Mine is 2". There is also a 1.5" model. The 2" works great on my carbines. I can see this being very valuable to police who can't just put on muff each time they shoot.

Quote form the S&J website:
Linear compensator is designed to direct the gas on a forward direction, away from the shooter. Its architecture has been improved from the classic layout of the linear compensator. As a result, the six side holes are no longer parallel with the bullet hole, but at a slight angle for a swirl effect. Also, the front end of the compensator is optimized to increase the effect of bullet stabilizing.

The outside diameter is .920",. At the rear there are 2 flats for wrench for easy installation

Threaded 1/2"-28tpi. CNC-machined out of steel, Matte black finish.

SLC-3 is the Standard Linear Comp with Dimpled finish 2.0 inch long

I picked up the 1.5", The Nano Comp for my 11.5".
I have yet to try it out. I am sure it will do what is advertised. At a fair price!

No indexing is required, but positioning of the Flats (Horizontaly or Vertically) may be aesthetically pleasing to some. And the dimples just look cool :)

rev im with you, I think the dimples are "dead ###y" ever since in got my first KAC I have loved the dimpled look.
think we will do a run of dimpled bbkls later this year or after #### show 2014.
we have over 12k shot in one of the NLC-3 and no damage yet, the CGNE finish is whats needed for high volume shooters.

Thanks for taking the time to test our product, Linear comps have been around for a while, but we found most were kind of boring looking and not very well finished.
The SLC is 2 inch long and the NLC "nano linear comp" is 1.5 inch long.
There is very little difference between the SLC and the NLC as far as how well they work, we just found that for Clients that ha 7.5 and 10.5 " bbl the NLC worked the best.

Comp,s are not flashiders, they work very well for recoil reduction and muzzle movement, with the ports being just on the front you get a nice straight push back, this helps keep you on target and faster follow up shots, without blasting the person next too you, or if you are shooting in a port (3gun , ipsc or idpa) or from a car or enclosed space it sends all the gas and blast forward so you don,t get major head damage or nose bleed.

What does increase the effect of bullet stabilizing mean? How is this done? What are the increases?

Cheers!

Don't know about flash, but the recoil was reduced. I know this because I usually shoot reduced power ammo in my AR and when i shoot full power (as in this test) I notice quite a bit more recoil. When I shot this device the recoil I expected was not there. It reduced recoil and noise. I did not run a full test of double taps to test muzzle jump, but it sure looked like the muzzle did not jump. Will look into that.

As a competitor I also know that muzzle blast can induce flinching, as serious issue for accuracy. So muzzle blast reduction will be worth points. I will buy the short one for the 7.5" barrel. It will look good on there.
