300 Blackout and TI-Rant Suppressors
I've seen several You-tube vids, and read several articles in other forums that the TI-Rant family of suppressors are fine for use with Sub-Sonic 300 Blackout Ammo. But I have not seen anything official on the AAC website. I did notice that most sub-sonic 300 blackout has about the same chamber pressure as a 45 ACP around 21000, But would like to know what AAC's official policy is on it.

Re: 300 Blackout and TI-Rant Suppressors
One might hazard the thought that direct contact with AAC might be an ideal starting place...

Scroll about half way down and you'll see Cade's response. Tirant 9/45 with 300 blk subs is GTG.

Re: 300 Blackout and TI-Rant Suppressors
Great thanks, now I wonder what the chance is that they might produce a 5/8 x 24 piston that we could use on it.

Not going to happen. AAC has been asked many times about it before.Gik-Tal wrote:Great thanks, now I wonder what the chance is that they might produce a 5/8 x 24 piston that we could use on it.
The only solution is to get a 5/8x24 adapter. Preferably a high quality one like from TROS.

Silencershop 5/8x24 fixed piston. Works great with subsonics.

Re: 300 Blackout and TI-Rant Suppressors
9 or 45 Tirant? Bolt or semi-auto? 16" or SBR? This question has been asked several times in this form and others, I suggest you read up on them to know what you're getting into. I asked AAC this the question directly and while they didn't say no, I got the impression that they highly discouraged it. Their posts on this subject in other forums are similar to the response I received.
Most people (non-AAC employees) seem to think the cans can take it. However if it was me (and I was in this situation a couple of years ago) I wouldn't do it. The Tirant made several sacrifices to be as light as possible in comparison to other can on the market. I don't think the aluminium baffles will hold up after a lot of sub-sonic 300 blk use. Most of the pistol cans that are rated for sub-sonic 300 blk have all stainless guts. 300 blk sub-sonics are really close to a 10mm in powder capacity, muzzle energy, and velocity (for a 220 gr bullet); they are almost as powerful as some of the smaller magnums. That's asking a lot from a can that was designed to be as light possible,yet strong enough to take the heat from full-auto rated common pistol semi-auto pistol rounds. These rounds (9mm, 40 S&W, 45 ACP) burn about 1/3 to 1/2 the powder of 300 blk subs. On a 16" bolt gun it won't wear nearly as fast, but on a SBR'd semi-auto you could destroy the can pretty quickly if you weren't careful.
For me, it wasn't worth destroying or significantly shortening the life of a can shooting a round through it wasn't designed to suppressed and doesn't do as good of suppressing anyway. I know you're trying to save money but it's false economics if you wear out the can and have to pay AAC to replace the baffles. I bought Octane 45 as my second pistol can and purchased a Thunder beast 30p-1 last year. I've shot my 300 blk bolt gun with both, and there is no comparison between the two. The Thunder beast with the 300 blk subs sounds like a big air gun. Oh, sure you can hear the crack of the ignition if you're shooting it, but if you stand a few feet away it sounds like the bullet is being propelled by compressed air rather than smokeless powder. The Octane 45 shooting subs sounds like a regular suppressed rifle, just without the super-sonic crack.
Keep in mind I'm only talking about sub-sonics, no pistol can with the exception of the Mystic to my knowledge can take the pressure of a super 300 blk . Tirants, Octanes, and similar cans from other manufactures will probably get their guts blown out on the first round if they are shot with super-sonic loads.

Re: 300 Blackout and TI-Rant Suppressors
Ive run maybe 800 rounds subsonics through mine. Mostly 220 grain HPBT's with 8.5 grains of H110 thorough a 10.3" barrel Ar-15 running about 1050 fps +/- a few fps . Ive had the can apart several times and not a hint of damage to anything. The H110 is most likely completely burned up by the time the bullet leaves the barrel. If anything the barrel pressure to 45 ACP when the bullet leaves the muzzle and the added clearance between bullet and baffle keeps terminal pressure in the can down. I don't get much of an audible difference between my 45 tirant on a 10.2" AR and a Specwar 762 on a 8.5".

Re: 300 Blackout and TI-Rant Suppressors
It's mostly about the muzzle pressure. Subsonic BLK is closer to a 45acp +p than 10mm.savagetactical wrote:Keep in mind I'm only talking about sub-sonics, no pistol can with the exception of the Mystic to my knowledge can take the pressure of a super 300 blk .

10mm is definitely a no no through a Tirant 45.
The Tirant isn't as well protected as some of the newer pistol cans. Not only because of the Al baffles, but the tube is also more exposed to the muzzle blast.
But the Tirant 45 is the safest bet for shooting 300 BLK subs. Larger bore and longer length. So pressures at the endcap are much less.
The Octanes are more robust than people realize. But officially, yes just BLK subs, no supers. The guts won't blow out if supers are shot by "accident"

Re: 300 Blackout and TI-Rant Suppressors
We're working on a dedicated 5/8-24 adapter for the Ti-Rant 45 that is essentially a piston and spacer all-in-one. We can't really make something like it for the Ti-Rant 9. When we designed the Ti-Rant 9 almost ten years ago, it was designed as a pistol silencer, not as a does-it-all silencer. As a dedicated pistol silencer, we used the same piston and spring that we used in the Evolution 9. The shaft on that piston is 5/8" O.D., which means there is no physical way to have a piston with 5/8" threads.
I hope to have the new adapter at SHOT 2016.

Re: 300 Blackout and TI-Rant Suppressors
Assuming you're still working on the 5/8 - 24 adapter (or maybe even have it by now for the SHOT show) will that adapter work on the Evolution 45? Refresh my memory, but don't the Evolution and Ti-Rant use the same pistons? I have another recent thread where I ask about shooting a subsonic .308 through an Evolution 45 (that I'm not really using much) if that's doable.SilentMike wrote:We're working on a dedicated 5/8-24 adapter for the Ti-Rant 45 that is essentially a piston and spacer all-in-one.

Re: 300 Blackout and TI-Rant Suppressors
Unfortunately the adapter will only be for the Ti-Rant 45 and the pistons for it and the Evolution 45 are different. Also, .308 subsonic is a no-go through the Ti-Rants. I highly advise against that.Robert Henley wrote:Assuming you're still working on the 5/8 - 24 adapter (or maybe even have it by now for the SHOT show) will that adapter work on the Evolution 45?

Re: 300 Blackout and TI-Rant Suppressors
Your'e losing me on that one. Assuming you are pushing a 220 grain bullet 1000 FPS down a .308 bore what difference does it make if it comes from 300 blackout shell casing or a .308 shell casing?

The Tirant 45 can most likely survive an accidental 556 or supersonic BLK going through it. But full power 308 would definitely cause damage with just one shot.

The velocity of a bullet and weight has absolutely nothing to do with what a silencer will handle. It is the pressure behind it as well as the unburnt powder. .308 subsonic is dumb in general, but really dumb through a pistol silencer.

[quote="NickAAC.308 subsonic is dumb in general, but really dumb through a pistol silencer.[/quote]
I disagree Nick I wouldn't call it dumb. Sure, most 308 bolt guns don't have a fast enough twist rate to take advantage of the heavy weight 308 bullets like most 300 blk guns can. However, if you're on a budget and want to shoot sub-sonics without having to buy a whole new gun and/or reloading setup its not that bad of a thing. For reloaders its pretty easy to do and doesn't cost you anything other than getting new powder and bullets.
To be honest, until someone makes AFFORDABLE 200+ grain expanding 308 bullet, 300 blk subs are nothing but a really expensive plinking round. For defensive/hunting use they are unsatisfactory in every performance category when compared to any other modern load/cartriage. For general plinking and target shooting, there are rounds much cheaper, flatter shooting, and have equal or better accuracy. The only place I know that they have a distinct advantage is in IHMSA pistol silhouettes (which is a dying sport to my Dad's dismay). In that game, the high BC of the 300 blk/300 whisper in the 220 & 240 grain loads maintains a lot of momentum that easy knocks down the full-sized Steel Rams at 200 meters.

Re: 300 Blackout and TI-Rant Suppressors
Why would it be a joke? Through a 45 Tirant a 300 BLK is OK pushing a 220 grain bullet 1000 FPS but a .308 pushing the same bullet the same speed probably using the same powder charge isnt? It doesnt make any sense other than if you were told to say it was OK for the BLK and not the 308.NickAAC wrote:I feel like this is a joke, but just in case it is not:YugoRPK wrote:Your'e losing me on that one.

Re: 300 Blackout and TI-Rant Suppressors
its not going to be the same powder charge and probably not even the same powder. 308 and 300 blk have very different case volumes and theres a lot more to it than just velocity and bullet weight, or else why not just throw a tirant 9 on a .357 mag. a 357 round gets roughly 1050 fps from bullets over 200 grains.YugoRPK wrote:Why would it be a joke?

reduced loads might be ok, they might wear the silencer faster. Probably wont blow the thing up but its still not the same as running a 9mm through it.
