I know the noveske kx3 and kx5 do. Are there any that maybe weigh a bit less?

Barking spider from Spikes

That creates back pressure, but doesn't weigh less. Especially if you leave the front flash suppressor prongs on.

I guess by "creates back pressure," you're talking about linear compensators?

Kaw Valley makes one that weighs less than half of the Noveske KX3.

I would assume most krink style brakes create a decent amount of backpressure, and the kak slimline flashcan is similar to the kx5, and pretty light.

+1 on the Kaw Valley one. Joe Bobs Outfitters had the best price when I bought mine.

They don't increase back pressure the way a Krink device (essentially a one-baffle suppressor) does.

Tada. Neither the kaw valley or the kak flash can create back pressure.. and they are not marketed as such.
He wants a kx5, kx3, or pws cqb. Not cheap, and not light.
May I ask why you are wanting to add back pressure to your system?

Another reading comprehension genius. Neither of those devices will change back pressure meaningfully.

Again, if you want to increase back pressure / dwell time for better cycling, you have to use some kind of krink design with a baffle like the KX3, Barking Spider, etc.

Wanting to shore up some cycling issues with a 7.5" barrel and heard this could help. I was hoping for something a bit lighter. Maybe it doesn't exist?
Link Posted: 3/1/2015 7:37:24 PM EDT
How about a longer barrel? When you attach a muzzle device, you are essentially making the barrel longer. Why not start there?

Lightening the reciprocating mass via lightweight BCG, Buffer and Adlustable Gas Block. I'm get ready to test my theory with subsonic 223 cycling with a 8.5" barrel with and without a suppressor.

That's a stupid idea when using pistol-length gas and 5.56. I had a case rip in half using a lighter-than-normal BCG/buffer combination in an AR pistol, because it was unlocking when there was still considerable pressure in the chamber.

I switched to a full-auto BCG and H3 buffer, readjusted the gas, and the problem went away.

hey asshole, unless I missed something here, I dont think anyone asked for smartass remarks...

I'm running a 7.5" barrel with a KAK flashcan, FA BCG, regular buffer and have not had any cycling issues yet.
Link Posted: 3/5/2015 1:25:34 AM EDT
Do you even reading comprehension, bro?

Some guns require a muzzle device that increases back pressure/dwell time to cycle reliably. If yours doesn't, that's great. But NONE of the muzzle devices you mentioned do what the OP asked for.

That's correct. Linear comps may boost backpressure a smidgen, but not to the same degree that a KX3/KX5 will. Due to that, the linear comp will cause less overgassing issues which may result from running a KX3/KX5 on 16" or longer barrels.

Since we're in the pistol forum, I'll assume he's talking very short barrel. In that regard, the Levang, Claymore and Kies Blast Master will increase dwell time enough to make them very useful on a pistol. The Levang is the best bang for the buck for increased pistol dwell time. It works well to solve some extraction issues (along with heavier buffers/carriers and adding a #006 viton o-ring to the extractor).

The Levang is easily installed with an inexpensive adjustable pin wrench. Big thumps up for the Levang (cause it's cheap and doesn't weigh much).

This is the correct answer. Once you attach a back pressure device you have made your weapon longer and haven't gained the velocity an extra inch of barrel would give you.

Except you're going to have some muzzle device anyway not a bare muzzle. You might has well have one that directs sound and adds dwell time (and it does it better than extra barrel because it momentarily traps a volume of air greater that the diameter of the bore slowing it's exit creating pressure dwell time). The small baffle on a Levang or Kies isn't as effective as the baffle on a Krink or KX3 but it does work.

Then add a suppressor. All of my SBR's work fine without extra long muzzle devices.

Were talking pistol length gas tubes not carbine. There are no suppressors rated for under 10.3" barrels. But there is merit to go with a 10.3" barrel over something less. It still helps to have a linear compensator if you happen to touch one off with out hearing protection. The moderators put on XM177s were designed to bring the decibel level closer to a rifle pressures. They could have went with longer barrels but they didn't.

I have two pistol gas uppers, a 10" carbine gas and 12.5" midlength gas. None of them need a linear compensator. None of them are hearing safe even with a suppressor. I run my 10" with a suppressor all the time, when it wears out, it wears out.

5.56 is a poor performer from a 7.5" barrel anyways. That short and you will get better performance from another caliber. In the case of the XM177 IMO they would have been better served with a true suppressor design, as it is the original moderators are still regulated.
Link Posted: 3/5/2015 12:43:38 PM EDT
Right, even your suppressed 10" isn't hearing safe. But it's doing less damage obviously.

I have permanent hearing damage from a Glock 17 touched off too close to my left ear about 20 years ago. Only takes one shot to keep those ears ringing. Something to keep in mind. Quieter is always better.

That weighs a bit more than a KX3. They should call it the Heavy Pig.

Bulgarian Krink "beer-can" style brake is your best bet.

This is for a .30 cal barrel, but they have one for a .223 as well.:

That's heavier than a KX3, too. The poster is looking for light.

That's the ticket. V7 makes interesting stuff. Like they've mastered titanium where others haven't.

Well, there goes another $130. HA! Thanks.

Now, if Faxon will just make an 11" pencil barrel.

Interesting, I'm not the only one that wants that short pencil barrel. Thanks for the heads up, I've never visited that forum.
