Hello fellow High-Roaders. I am in the market for suppressors for a .45 carbine and .300 AAC SBR, and am seeking recommendations from the group knowledge herein.

I have a Gemtech Alpine for my Ruger 22/45 and it is light, easy to clean, and suppresses .22 LR very well (looks like their only option is the Blackside for .45 and they have a few for .300).

I am looking for the same characteristics noted above (weight, cleaning, performance) so any recommendations you guys can provide (and why) would be great. I have shot a few friends' versions of both calibers but these guys seem to be single-minded when it comes to manufacturrer preference.

Much thanks in advance.
 
If you don't mind a slightly louder report from the .300 AAC, you could find a suppressor for the .45 that would be STRONG enough to handle the .300 AAC (I believe the .300 AAC MIGHT have a little more pressure at the muzzle, but I could be wrong). Surprisingly, many suppressor used on smaller bored weapons work quite well; i.e., a .308 can on a .223. I have used a .45 can on a 9mm barrel, and 9mm cans on .22's. I cannot give you a specific suppressor for your needs, but several makers can supply a "lock out" fitting to alter a Neilson assisted suppressor (recoil booster) for use on a fixed barrel weapon. One is the AAC Evo series.
 
I'm a fan of Thompson Machine's cans after having shot a few of them. They had so many people using their ISIS-2 9mm can on their .300 BLK hosts that they made a .300 BLK version of that can. They've also just released a .45 version of the ISIS-2. I shot it on a .458 SOCOM AR15 and I liked the way it sounded. If you're looking for a single can for both applications, take a look at the ISIS-2 in .45. It will also handle .300 BLK subsonic pressures, I'm sure, since their 9mm can does. It's probably not rated for supersonic .300 BLK. The ISIS-2 comes apart really easily for cleaning, by the way.

(If you have questions about their line, e-mail and talk to Brooks. He's their sales guy and is very knowledgeable. Their website may not be current with some of their new cans.)

I'll be happy to report more first-hand knowledge of their line when my ISIS-2 9mm finally gets approved later this year.

Unless you intend to stick with subsonic .300 loads i believe your only option will be a large bore silencer and it may be tough to find a user serviceable one. They will also be fairly heavy. There are plenty of pistol caliber cans in .45 that can be used with subsonic .300 though. I really like the Osprey but it isn't user serviceable. You'd have to double check to make sure they are useable on subsonic .300 but i'd look at the Ti-Rant and the Octane. You'll of course need the spacer for fixed barrel use.
 
I decided to go with the AAC Cyclone for my .300 AAC. Cost, availability was the driver for me. Got one at the lgs for $750 and since the rifle will be shot with subs only, it should fit the build nicely.

I have shot supersonic loads out of the rifle to ops check the build (my own) and now that the can is in the works I will only reload subs for it.

I got the impression that the OP is asking about a single can for both .45 and .300 in which case the cyclone would not be an option.

Thats what I was thinking for the .300 - all subs. Every .223+ I have shot with a can, only the "edge" is taken off the report so looking to mitigate the rifle crack a little more for the .300. I think that can only really be done using subs, or a can the size of a liter soda bottle!
 
I went with the Silencerco Osprey for my HK USP 45. Very quiet can and works well on 9mm too. I just dropped off my Marlin camp 45 to have the barrel threaded. I think it will be a lot of fun when finished.

My 7.62 can is the Thunderbeast 30P1

If all you intend to shoot is subs i would just go with a single .45 can that can be used on the .300 too. I would also suggest going with something like the Osprey or TiRant so that it can be used on non-fixed barrel pistols as well in case you want to do so in the future. If you do buy two cans i'd say just do some research and choose a good .30 can. From exprience i suggest going with something light. Slapping a one a half pounds on the front of an AR significantly affects handling in a negative way. If all you intend to do is shoot from a bench then weight is less of an issue.
 
I was in the same boat as the OP. I went with the Osprey. It obviously works well in .45, but what surprised me was how well it worked with 9mm and .300 BLK.

My girlfried opted for a 9mm Osprey and I'm convinced that the .45 model is quieter in that caliber. (Should this be a surprise? Has anyone noticed how much larger the .45 model is?) As for .300 BLK, a friend compared the sound to knocking on the door with the butt of the rifle. I was developing loads and we didn't do enough shooting to really make up our minds, but both of us were extremely impressed by how well it did. I was shooting it dry, and it seemed significantly quieter than the .45 when wet.

Just make sure that your bullets are subsonic and stabilized prior to attaching the can. I had no issues here, but it's a bad situation to have issues in. Make sure.

My two big complaints on the Osprey are that it's not user serviceable and it's aluminum. I know why they opted for this and I understand it, but it's proving to be a headache for me. I could be saving a whole lot of money by shooting cast bullets and dipping to clean, but that's not an option.

Thanks Dave. I'm with you on the versatility but user serviceable is important to me. I like the Osprey for the reasons you state but want to be able to clean it.
