I've been looking into a Krinkov style device for a 5.56 SBR. The controlled gas expansion and increased back pressure features seem vital for the short barrel. How do the new "blast diversion" devices compare to a traditional Krinkov 2/3 piece system?
I'll post a pic of some for clarification. The new style looks like a can with holes drilled into it's front face. This seems like it would restrict gas expansion and gives some back pressure, but it's missing the Krinkov cone muzzle to direct the blast.
OP is a pic of a three piece Krinkov device. Here's it broken down. You see it forms an expansion chamber in the can, while the cone muzzle directs the blast.
Here's a Midwest Industries Blast Diverter. It's a can with holes in the front to restrict the pressure. Seems like it wouldn't be as effective as a traditional krinkov, but it keeps getting recommended for SBR use when i look online. Anyone use one of these new nozzled can things?
my assumption is that the only real difference between all of the "linear compensators" is aesthetics. all the blast is going out in the same direction on each one
youtube.com/watch?v=FFk6Jv5C_qc Here's a Troy Claymore blast diverter. It looks to be really nozzling the blast, but it's size makes me think it has limited effect.
The expansion chamber formed in the 2/3 piece Krinkov maintains back pressure longer, which improves reliability in SBR gas systems. The linear comp/blast diverters look like they would increase pressure, but for a shorter time. And they seem like they would not direct the sound as well.

The Troy Claymore does look to have a cone muzzle. It doesn't stray too far from the original Krink in design principals.
Don't try to solve gas problems with a muzzle device. Get an adjustable gas block for that.
Only reasons to get linear comp or krink is for aesthetics and to be nice to others at a packed range

And because i don't want an explosion in my face.
Tyler Wright
Adj gas blocks are for overgassed systems(ie: carbine length gas port in a 16" 5.56 barrel), suppressor adjustment, or specific load tuning. The first two are for MITIGATING gas going into the carrier. With a krink or dissy length AR, they're severely undergassed, like less than an inch of dwell time. Linear compensators are shit for helping with this, a 4-piece ak brake, or a noveske flash can are basically your only options. Adjustable gasblocks and Blast diverters like the SF Warden do fuck all for increasing backpressure
Samuel Hall
This. I have a sig "pistol" AR and the short barrel blasts your face with each shot. Still fun though.
Ethan Moore
Here's a thought: don't play with SBR's that are NOT supposed to be chambered that way... INB4 such things as 300 BLK Out, and 458 SOCOM... DUDE!!!
Luis Jones
are you some kind of retarded, boy?
Aaron Williams
Isn't this Noveske pretty much exactly what you're talking about?
That looks like an open can. That won't increase and maintain back pressure like the Krinkov. It may have the same or better flash and blast direction. I've heard people on the forums say the Noveske/Krinkov is definitely quieter than an open can. Get a high quality Krinkov like the Screaming Banshee. They're made with better, lighter steel. The SB is 7.8oz while most cheap Krinkovs are 10+oz.
Jack Sanders
The Krinkov will definitely improve reliability on short barrels like yours. Anything less than 7" of barrel past the gas tube should have one.
Brandon Sanders
My upper with guntech flash can is a hair too long for hard case. What is shortest linear comp, flash can, krinkov out there? I think my pistol might be over gassed so doesn't need more back pressure but rail does go longer than barrel.
Jack Martin
The shortest, and lightest, Krink I've found is the Screaming Banshee three piece(OP pic). It's 3.25" long, so that 3" added to the barrel.
I have one of those. It works pretty well. Shot it at an indoor range and didn't seem to be a problem. Took it off to put a comp on and noticed gun was a bit more loud.
Cooper Smith
Get a Noveske KX3 and move on.
Kevin Wright
Aim is selling one that's 2" but I hate the color (titanium) and it's $130.
I don't know what that short one is?
Joseph Williams
Well, never mind it looks like a guntec micro, just ordered one off primary arms.
Christopher Bailey
You made me have to go and weigh my $20 chinc krink from ebay.
The Screaming Banshee comes in a two or three piece design. The two piece is a little heavier than the 7.8oz three piece. Yours looks like a good two piece. How does it compare to your other brakes and cans?
Zachary Evans
Exactly, so it’s a silencer according to the nfa. It lets some gasses expand and cool and reduces the noise by a few dB.
Nathan Rivera
I has the Piggy version. Love it.
Caleb Cook
People say this brake also reduces flash quite a bit. Are there any other brakes that work good for flash as well? Specifically ones that are cheaper and come in 5/8" thread?
Judges and the ATF's arbitrary and capricious rulings hold the weight of enforcement, not the actual law. They are NFA items if and only if the ATF says so and a judge agrees in the event of a suit. Likewise if they want to ban something that does not in any way meet a definition, like 7N6 as AP, they can as long as a libtard judge says, "Aight". Also, just a tidbit, the GCA defines silencers, not the NFA.
Jaxson Sanchez
7n6 is by the retarded legal definition ap from an unconstitional and bullshit ap ammo ban from 82, that was only ever meant for hand gun rounds not rifle rounds. If the core is 25 percent or more of x material, it’s ap, x material includes steel and 7n6 is steel core.
Oliver Reed
I wonder what the legality of packing the single chamber with some rolled up fine mesh screen. would be.
Jose Wood
>(i) a projectile or projectile core which may be used in a handgun and which is constructed entirely (excluding the presence of traces of other substances) from one or a combination of tungsten alloys, steel, iron, brass, bronze, beryllium copper, or depleted uranium; or >(ii) a full jacketed projectile larger than .22 caliber designed and intended for use in a handgun and whose jacket has a weight of more than 25 percent of the total weight of the projectile. Look carefully. >which is constructed entirely (excluding the presence of traces of other substances) >or >larger than .22 caliber It is neither constructed entirely of steel nor larger than .22 caliber.
Isaac Cruz
But is constructed almost entirely of steel. Steel jacket and a steel core.
Luis Ramirez
The jacket is purely steel, yes, but the jacket is neither the whole projectile nor the core. The core is lead and steel. Lead and steel is not entirely steel. >almost entirely Almost? Well shit, I guess as long as it's almost illegal it better be banned.
