Silencerco / SWR released a badass mamma jamma of a 7.62x51mm/.308 Win. muzzle can (silencer/sound suppressor) recently at SHOT Show 2013 called the SPECWAR 762. It's DefenseReview's (DR) opinion that the SWR SPECWAR 762 suppressor's attributes and capabilities are going to be tough to match, let alone beat, particularly when it's combined with the Silencerco Trifecta pingless (no resonation) open-prong (3-prong) flash hider/flash suppressor/quick attach/detach (QA/QD) suppressor mount.

The 9-inch (9"), 24-ounce (24 oz) SWR SPECWAR 762 suppressor mounts and detaches fast, and won't torque loose during heavy firing, thanks to Silencerco's/SWR's Active Spring Retention (ASR) tech. Since the carbon fouling is sealed off the Trifecta's suppressor-mounting threads, there won't be any carbon locking. Then there's the Trifecta's knurled ring. "That knurled ring interfaces with some spring-loaded teeth on the inside of the silencer. So what happens is we screw it down to shoulder, just like that. Then you turn this locking collar, right there. That makes those teeth go in and engage that knurled ring. So this silencer's not going to back off under rotational forces caused by torque when your firing it, so it doesn't work its way loose," says Silencerco's national sales manager, Gary Hughes.

The result? Superior accuracy and repeatability–with no baffle strikes! Another really cool aspect of the SPECWAR 762 is the baffle material. The whole baffle stack is made from an metallurgically-advanced material that Hughes claims is stronger than Inconel, yeilding unequaled 30-caliber abrasion and heat resistance. This means the SWR SPECWAR 762 is strong enough to handle 300 Remington Ultra Mag, which is billed by Remington as the "hardest hitting, flattest shooting .30 caliber factory offering in history and is known throughout the hunting world for its accuracy, velocity, and unmatched ballistic performance as a big-game cartridge."

Oh, and by the way, if you're running a Silencerco Trifecta RS Flash Hider/suppressor mount on your tactical AR-15 5.56mm carbine/SBR (Short Barreled Rifle), you can mount the SPECWAR 762 on it and use it (5.56)! Sure you give up a little sound suppression versus a Silencerco Saker 5.56 can, but it's still much better than no sound suppression.

Pretty cool, and a nice follow-up to the Silencerco Saker 5.56 suppressor, which DR covered shortly after SHOT Show 2012.

The following information on the SPECWAR 762 comes directly from the SWR website:
