Suppressors KAC PRT Suppressors

[rbutcher]

These have been teased before as something in the works, and we’ve seen them in the 2020 catalog. Is there any timeline for these being released to the civilian market?

A very low back pressure suppressor with high durability, absolute minimal length, and great flash reduction is top of my list, and these appear to check all those boxes.

I cannot speak for the manufacturer, and never would presume to do so, but from what I have seen and been witness to, KAC has not taken suppressor orders from dealers in a year, and with ear to the ground, I have heard nothing about suppressor manufacturing, let alone orders and distribution. Many, many dealers have been waiting a long time to be able to place orders, as demand remains high.

Many of the higher-end rifle companies have been concentrating all available raw materials, machinery and labor on rifles. We just got a shipping notice from LMT today for specialty rifles we ordered 2 years ago, and LMT stopped taking orders 18 months ago, and with limited exceptions is not taking large orders yet.

So it sounds like these are a very, very very long way off?

If this is your main criteria, then, in the meantime while you're waiting, I would look at a Dead Air Sandman-S. With eForms you'll get it back in hopefully 90-120 days. Might as well be shooting suppressed in the meantime, while you're waiting on the KAC can to drop. And the Sandman-S is a great can. You won't regret the purchase...I have 2 of them in my lineup. Very low back pressure, and for their size, they're relatively quiet, and sound very good (deep tone). And it's full-auto rated, no barrel length restrictions, and rated up to .300 WinMag.

For my criteria, the Sandman S is too long.

Sandman-K, Otter Creek Labs Polonium, Energetic Armament VOX-S are all fairly short with good suppression and hard use rated.

 

[rbutcher]

I have a sandman-k, it fails in the flash department even with the 556 flash endcap. It's also longer than it needs to be for a 556 can. Its 0.4" longer than a KAC QDC/CQB, Surefire mini, or the CQB PRT, which do become direct comparisons once you make the decision to attempt sandman flash reduction using caliber specific endcaps.

Edit: I should clarify that I am not putting this on a 10.3 or 11.5 and expecting full size suppressor performance out of micro cans. This is all on 12.5 barrels, which is why the length criteria is important. The goal is to end up with the same OAL as a 10.3 and full size can, but with 2" more barrel, similar flash reduction, and minimal backpressure. From what Jack has posted about the PRT, they apparently do very well with flash.

 

[Clayman]

From what I've heard there is no timeline for any 556 can from kac for a while and I'm sure these are even further out than the regular qdc cans.

Higher flow designs usually have a bit more flash in my experience.

The oss 556k is what you want for minimal backpressure

I can't speak to the flash but the new ones with the built in flash cap is supposed to be better than the previous model.

 

[WillHugh]

Allegedly all of their supressor capacity us tied up making NT4s for the marines. They're not going to be taking commercial orders for a while, and there's a huge pent up demand for the QDCs already (some of them are going for north of $4k on the secondary market).

My best guess is that it will be years before any KAC can is readily available, let alone one that hasn't been released to the commercial market yet.

The rc2 mini might be worth looking at. It will be higher back pressure than the PRT, but should have better flash suppression.

 

[kthomas]

I've been periodically following the availability of KAC suppressors for years, while toying with the idea of getting a KAC suppressor to mate up with my SR15.

KAC suppressors have seemingly always been pretty hard to come by. There's been a recent surge in demand for KAC products, and combine that with their military contracts, supply for the civi market is extremely limited.

I wouldn't hold your breath. Will probably be a long time before they are available, if I was to guess.

 

[TheOE800]

They aren’t order-able nor do they have a pricing model in place yet. Considering the backlog of QDC cans, I’ll be shocked to see PRT cans in consumer/civilian hands before 2024.

 

[rbutcher]

Everything sounds like these must be effectively a pipe dream at this point

 

[TheOE800]

KAC could always surprise everybody and release them tomorrow.

Not sure about blowback yet, as mine hasn't arrived to the dealer yet... But that new Otter Creek labs Polonium is a duty-rated 17-4 stainless 5.56 can. It just scored above everything else on PEW Science for being the quietest 5.56 can on the market. Now, I don't about blowback, port noise, or back pressure, or anything like that...YET... But at only a $550 MSRP, it's worth looking into. Mine should arrive in a few weeks, and I'm pretty excited about trying it on my 14.5" 5.56.

It's the highest back pressure 5.56 can tested by Jay so far. It will need tuning to be optimized.

I get that to some it might be a big deal, but to me I already run an H2, and adding an AGB isn’t more than 30 minutes of work…Taking my time and being OCD about everything.

But I get that to some cloners, and those who might not have the knowledge or tools to build rifles, it might not be their cup of tea.

 

[rbutcher]

To be fair, I also prefer to not have an AGB on a hard use rifle. But that problem is easily solved with a BRT gas tube.

Regulation of the gas system is easy but the blow back into the chamber and receiver makes it a pain. Either clean more frequently or run into problems sooner.

H3 buffer helps slow down your unlock time, increasing chamber dwell, thus helping to eliminate both excess noise and chamber blow-back. It also helps keep it cleaner. Since swapping all mine to H2 and H3 buffers, it's been night & day in cleanliness...Even with subs in the .300 BLK. and a carbine length system with a non-adjustable gas block, I can shoot hundreds of rounds of subs through my .300 BLK now, even with my high BP suppressors and no gassing, and it stays fairly clean inside the receivers. The bolt & BCG still gets dirty, and I do regularly clean them every few hundred rounds, but other than that, a quick wipe-down with a RemOil cloth inside the receivers while I already have the BCG pulled, shows very minimal carbon (blowback).

I do plan on swapping in an AGB soon, just to tune it even more, to keep the bolt & BCG cleaner, but I haven't gotten around to it yet...It runs fine for now, and I got other things to work on first.

That's why on my 14.5" 5.56 (carbine length gas) i'm just running and H2 or H3 buffer. It helped noticeably. My standard gas block is pinned, and it runs great with not a lot of gassing (properly sized barrel port). The Rainier Arms stainless gas tube is nice, too.

How about the new DA Sierra 5? Looks pretty good so far.
