EddyB Posted March 30, 2016 Share Posted March 30, 2016 I am building my first SBR (300 AAC) with an 8.5 barrel and of course will be putting a Can on it but there are many options out there and I'm trying to get some advice on which one to go with, most likely it will be the only one I get for a long while because of cost and process, a multi caliber would be nice for versatility ( l've been told to get 30 cal ), I would like to keep the cost around $800 but I am open minded :-) Any advise is appreciated. Thanks in advance. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
rhowell309 Posted March 30, 2016 Share Posted March 30, 2016 The AAC 762SD (not the SD6) is the quietest can I have heard. It will work with super and subs. Works with 223 on 10.5"+ barrels. There are some 9mm solutions but they will not be as quiet and most will only handle subs. It really depends on what other calibers you want to cover.

vixty Posted March 30, 2016 Share Posted March 30, 2016 I have a Templar 9mm can and it can handle anything from a 22lr to a 16in barrel 300wm. Its also rated for automatic fire. they cost around 1100 though. Link to comment Share on other sites More sharing options...
steviesterno Posted March 30, 2016 Share Posted March 30, 2016 i have an 8.5" 300 upper and have been reading up for the same thing. I'm leaning towards an Osprey 45 since it will work well with 300 subs (ONLY!) 9mm, and 45. but I also want just one can to work on everything. I don't like suppressed 223, it's still pretty loud. I also don't shoot 308 but I do shoot 45s. so that's my thought process. Link to comment Share on other sites More sharing options...
RangerTrace Posted March 30, 2016 Share Posted March 30, 2016 Silencerco Omega. If you're only going to do one can, which is fine and smarter than what I did, get one that will do it all. Link to comment Share on other sites More sharing options...
Nathanb Posted March 30, 2016 Share Posted March 30, 2016 I've got a Yankee hill lta30 can and I'm happy with it. You're going to be hard pressed to find a can that suppresses a wide range of calibers well look for Inferchangeable end caps in order to do so. Here's my 8.5 300 Link to comment Share on other sites More sharing options...
yellowfin Posted March 30, 2016 Share Posted March 30, 2016 Silencerco SpecWar762 has been doing amazingly well for me the last 2 years and fits on everything I have. The price was right and it's very durable. Link to comment Share on other sites More sharing options...
Paul-the new guy Posted March 30, 2016 Share Posted March 30, 2016 I just went through this same decision process. I ended up buying the Rugged Surge 762. To me it seemed like the right choice, If you buy a few accessories, it is like 4 suppressors in one with one stamp. I got the Surge and added the 5.56 end cap and an additional 5.56 brake. It was a a little over $1k for everything. One additional factor that sold me is it has a 100% unconditional warranty... blow out the end cap or have some baffle strikes because of crappy ammo send it in and they will fix it. Now if I could just buy some patience to help me wait on it... https://ruggedsuppressors.com/product/surge-762/ Link to comment Share on other sites More sharing options...
BrianKr Posted March 30, 2016 Share Posted March 30, 2016 (edited) I don't know of any manufacturer that suggests shorter than a 10" barrel with bottleneck cartridges. I've been using a Surefire FA556k for years now and it works great. I love the quick attach feature, and the new QA feature is even better. It's Hollywood silent with a subsonic load, and there is only 1/2" impact shift with or without the suppressor. I don't think they make the FA556k any more but I doubt that they've dropped the quality. I know that they make .30 cal suppressors too.

Nathanb Posted March 30, 2016 Share Posted March 30, 2016 You're shooting 5.56 and its that quiet? Subs or supers? I didn't think 5.56 suppressed well especially with 300 blkout comparisons Link to comment Share on other sites More sharing options...
BrianKr Posted March 30, 2016 Share Posted March 30, 2016 (edited) Yup, from the perspective of the shooter the hammer strike is louder than the noise of the round. Since the bullet is subsonic all one hears is the bullet impact after the hammer strike. I'm shooting them out of a short barreled Contender. Too, I don't have a .30 cal suppressor that I'm shooting .223 through. It's a dedicated 5.56 suppressor and that makes a difference. When I shoot it at a public range and it never fails to attract people. I give a demo of w/o and with the suppressor just to show that it really is a firearm. Of course there is no recoil to speak of; it's much like dry firing, except of course it has a lethal projectile. There are thousands of subsonic loads. Here's what I'm using: .223 Rem Super 16 Contender |Subsonic @ 1013 fpsHornady .224 33 gr V-Max w/FASTEXCCI 450 small rifle magnum primer 2.0 gr Green Dot 2.110 C.O.A.L. Accuracy is good out to 50 yards then the groups begin to open up. I don't have much experience with .30 suppressors, but I see no reason it can't be made very quiet indeed using fast powder and keeping it subsonic. No chrono' needed; you'll know when it's a subsonic load. BTW, the above load with a hair more powder goes supersonic and it's entirely different. Noisy once again.

Nathanb Posted March 30, 2016 Share Posted March 30, 2016 Got it that makes sense then and easier to achieve subsonic in a bolt or single shot platform. I run all mine in an ar platform. Here I though I was going to be buying another dedicated caliber can but it may not be plausible for what I'm doing Link to comment Share on other sites More sharing options...
BrianKr Posted March 30, 2016 Share Posted March 30, 2016 (edited) It is possible to do subsonic in an AR, but contrary to the way one would ordinarily work up a load, you'd need to start sort of high and work down. The problem is the gas hole. If one starts low the gas will be lost and the bullet can get lodged. The hiss of pressure escaping means you've got problems. Don't ask me how I know that. :-) If you want an AR subsonic load I can supply it, but it uses 80 grain Sierras and they must be individually loaded. They won't cycle the action. The 80 grain bullets also require 1:7 twist and even with that they'll begin to destabilize before 75 yards. At 100 yards they are keyholing. Penetration is some kind of incredible; 13" in dry hemlock and they will tumble a few inches in. For a few inches they cut a swath almost 1" in width. Edit: Oh, and you shouldn't load the same low pressure brass sub sonic over and over. The brass will actually shrink if that's done. The cartridges that are designed for subsonic and full pressure can be reloaded over and over, but not my loads. I don't remember their names, but I know JD Jones has some, and one of them was appropriated and renamed something else. I seem to remember it being a .30 and using a very heavy bullet. Actually that cartridge is an AR cartridge. If someone has a .30 suppressor I'd look into getting an upper for it. Silent suppressed is really too cool!

shakman Posted April 1, 2016 Share Posted April 1, 2016 +1 on Silencer Shop. Good guys, and great place to shop. If you're going to stay subsonic, the Octane HD .45 is a grand choice. It'll work with 300BLK subsonic as well as any non-magnum pistol caliber you want to throw down the tube. It's completely user-serviceable and works great. I've got a buddy that uses one on his FA MP5, and its STUPID quiet. I tried mine on a friends 300BLK and it also was very quiet. Link to comment Share on other sites More sharing options...

RangerTrace Posted April 2, 2016 Share Posted April 2, 2016 It you want to run a .22 caliber bullet subsonic, seems like it would be a lot less trouble and less expensive to build a .22 long rifle. Link to comment Share on other sites More sharing options...
BrianKr Posted April 2, 2016 Share Posted April 2, 2016 It you want to run a .22 caliber bullet subsonic, seems like it would be a lot less trouble and less expensive to build a .22 long rifle. Cost of a subsonic round: < $.10 Time required: A few hours for load development, after that about 2 seconds per round, tops. Cost to send a barrel out for threading : $150 Cost of a .22 suppressor: $300 (?) Cost of NFA paperwork: $200 Time required: The first time 6 months, I don't know what the wait is today.
