Default Noveske KX3 vs. PWS CQB Comp

Anyone own both?

I have a KX3 and think it does a great job on blast (noise and concussion), not so hot on being a FH. It also helps with cycling short stuff (a bit like a suppressor).

Any reports on them?

Also, does anyone have a pic of the internals or disassembled PWS (like the KX3 one below)?


11.5" pistol is the intended upper.

Eye candy for the unaware:

PWS

KX3

My only comment is the PWS is a bit heavier. (felt weight...never weighed them).Tried both...kept neither.

Never took the PWS apart.

Really? I've always read the KX3 is a heavy bastard and its about 3" long so you're looking at a 14.5" overall barrel length.
Never seen the PWS but everyone says the KX3 is badass. I've seen pictures of how well it works and I thought about getting one on my SPR but everything I read said its a waste of good $$$ on anything 14.5<

Actually....14.5 is still a bit long for a booster like a KX3

yes.

It's really appropriate for the true SBRs.

Why did you dump them? I'm mostly looking to tame the blast - cycling help is good, too. If the CQB helps with being a FH it's just bonus.

I tried both on my pistols....

A) too front end heavy for my taste.
B) my pistols cycle fine without them (I'm guessing the gas port is GTG on mine)


I can't really say much about flash on the CQB...I used it only in the day.
The KX3 is really neat at night though and I'm sure thats exactly why there is a flaming pig on it...for me it only emitted a small yellow/blue flame that was squiggly like a pigs tail.

I have the PWS on my Diablo AR Pistol. I frickin' hate the thing, It's a flame thrower at night. I want to try the Noveske pig to see if it helps with the flash suppression or not. The PWS CQB comp has an internal chamber to help build up back pressure that's needed with the short barrels. I'm going to try the Noveske pig next week sometime. I'll report back...

Can you disassemble your CQB and post pics?

I think the biggest problem with flash is there's just so much unburned powder with a short barrel in an AR. The rounds are designed for longer burns.

The CQB projects the muzzle blast forward, and it is perfect for CQB applications.

The CQB flash hider prongs really help to keep muzzle flash down, but some guys have reported seeing a small flash now and then during night shooting.

The CQB has a small chamber, and you can remove the front half of the comp for cleaning.

It is just slightly heavier than the KX3.

PWS CQB on a 10.5" ATAC GPU I built.

I have a couple of the CQB's at the shop, and I can disassemble on tomorrow and snap a couple of pics for you.

I have not tried the Diablo without the CQB on it, since it is a part of the Diablo Piston System, and I believe you might run into some cycling issues if you remove it and use anything else.

I have tried it without the CQB, it does not cycle period. Just curious, where did you hear "The CQB flash hider prongs really help to keep muzzle flash down, but some guys have reported seeing a small flash now and then during night shooting."??? I would have to disagree with this whole statement. I shot with it at night and beleive me, we are talking 1-2 ft flames!!!! totally blinds you at night.

Ammo choice makes a difference, too.

I tried Hornady 75gr TAP, 62gr Lake City and 55gr. American Eagle. Any other suggestions?

I would be shocked if they all appeared the same from any FH, but I don't know how well any of them would do with the CQB, as I haven't used one.

Interesting...

They were not all the same, least flash was with the AE 55gr. I know its a tall order with CQB uppers... Short of moving to a free state, getting a suppressor I think I might be SOL

you still have to deal with first round flash. Some more popular Mfg's like AAC recommend dipping in water and draining or 5cc (a water bottle cap full) poured into the rear of the can...

In all honesty...some of those things flash in the day time. I was a bit disappointed to find out that most of the promising companies weren't all I thought they were.

This is some good info.

I've got the KX-3s ugly brother, the Krink, on my 13.7" CMMG CAS. I've been told by other people with that upper and people that have the KX-3, it doesn't work that well as a FH.

Krinks and KX3's are NOT designed to be flash suppressors.
The original Krink was designed as a pressure reservoir to help the Krinkov cycle with so little barrel past the gas port.
On AR's they do the same thing for short barreled rifles.
Another thing they do is to throw the concussion FORWARD of the gun.
This is very useful from an entry team perspective where you have 3 guys side-by-side moving in close quarters.
Beyond SBR's, there's no real functional need for them.

Putting them on because of looks is flat-out...

Having spoken to a few of our customers who purchased Diablo's from us.

I have heard that the CQB flash hider prongs really help to keep muzzle flash down from these customers who are shooting the Dialbo, but I was not trying to imply that it eliminates flash.

The CQB comps secondary (not primary) purpose is flash suppression.

If you are unhappy with the flash suppression of the CQB on your Diablo, just let PWS know.

(Edt: One other thing to consider, as was already mentioned, is the type of ammo being used. Some types of ammo might be loaded hotter, and you will get a large flash signature from many different types of muzzle devices, inc. most flash hiders, except maybe for the AAC FH. Unfortunately you really do not have any options with the Diablo, since the CQB is a part of the piston system, and it will not run properly without it.)
