Suppressors Best KAC muzzle device for KAC QD cans?

[TheHorta]

KAC-specific question: Which works best? Simple Flash Hider? Brake? MAMS?

I know a lot of cans function better with simple hiders rather than ported brakes — some a LOT better.

Not sure if that applies to KAC.

Never intend to shoot unsuppressed, so that variable won’t matter. Just wanna know which makes the can perform optimally.

5.56 or 7.62? The MAMS is out of production, so 7.62-wise I think the two port brake is your option for blast baffle erosion mitigation and what not. On the 22cal side there is no brake as of yet and said MAMS is again out of production.

 

[TheHorta]

Yeabbutt… I can pay $800 and get a MAMS for my .22 to go with my $2000 22cal, 18.7# KAC can.

You poor people say dumb things.

I have my MAMS and KAC cans as well, rich boy.

Don’t get argumentative with me, boy.

For QDC suppressors, current 5.56 suppressors are primarily tested/developed for performance with the 3-prong flash hider, as that's what the programs that caused their creation were centered on. Using a QDC-compatible brake or Mini-MAMS will give slightly different results in flash/SPL/backpressure, but not drastic.
In 7.62/6.5, the open brake (current standard) is what the suppressors were built around. Again, the 3-prong, 5-slot, 6-slot, and MAMS will show varying degrees of different performance, but within the same general performance spec. Be aware that old "long-tine" MAMS may show compatibility issues with newer suppressors, which is why we made the revision with the shorter tines several years ago.

And here I thought I overpaid when I got my my MAMS for 350$

3-prong it is!

Thanks for the legit answer.

I’ll get that miscegenated bastard HUX brake off the tip of my pureblood KAC CQ post haste and return the simple 3-prong to its rightful position of glory and honor.

For academic purposes, this is what’s going on a factory 11.5 SR-15:

KAC secondary market is crazy. I sold my KAC Triple Tap brake for over double what I originally bought it for.

Yeah aren’t the 16in ECC/EMC URX 3.1 with the dimpled barrels worth like 12K now ?

I'm sure whatever it is, it's an incredibly stupid inflated price

Use at least 0.075 of shim when you install the 3-prong if your 11.5 is a Mod 2/10.5" URX4.

care to share when and how much that was? ive been sitting one for a few years... trying to get stupid prices for it and maybe with it attached to an all original Mod 1.

I sold it for around $1k a year ago.

I think the new additive manufactured version might have put a dent in that market.

Care to lift up her skirt, and show me that blast baffle?

As soon as it gets here, yessiree.

Wound up using a standard crush washer and it just happened to time perfectly at torque spec.

How do you like the PTR? I shoot with a guy who runs one in 2 gun matches and I really like the tone and find it very quiet in a 14.5”, but it’s much heavier than I expected.

Yeah, that’s the single knock against it — weight — but… on the 11.5” it seems perfectly balanced, so it doesn’t *feel* heavy on the front end when snapping the muzzle up from ready. KAC-Jack explains that the can was specifically developed to sustain 300 rounds of continuous F/A fire through a 249 belt-fed, which is WAY higher than the SOCOM Surge requirement.
