AAC M4-2000



The worlds most effective 5.56mm silencer just got better. The AAC M4-2000 Mod 08 features the patent pending fast-attach Ratchet-Mount to provide precision accuracy with minimal and repeatable zero-shift. Users have the ability to install or remove the silencer from the Blackout flash hider in seconds in the harshest military environment. The compact size and light weight have minimal affect on maneuverability. The M4-2000 Mod 08s extreme durability is maximized by CNC automated fusion welding of every high-temperature aerospace alloy component used in its construction- making 100% suppressed full-auto fire possible on barrels as short as 10 inches. The back-pressure lowering design of the silencer aids in shooter comfort, reduces weapon fouling, and minimizes cyclic rate increase. As a final step, tapered-bore EDM technology is utilized to ensure precise bore alignment resulting in enhanced accuracy and maximum performance. By eliminating approximately 97% of the muzzle report, the M4-2000 Mod 08 preserves the hearing of the shooter and nearby support personnel, facilitates communication, and masks the location of the weapon. Eliminating muzzle flash in combat saves lives.


As of July 2015, all M4-2000's will now ship with an included 51T Flash Hider in 1/2x28!

    51t mount is solid and the can itself is well made. Fired one 30 rd mag off the patio when I got it home. Didn't get any comments from the neighbors so the can must work. My son shoots left handed and was whining about blow back but that's to be expected. I may order an adjustable gas block or he might just have to toughen up.

    The M4-2000 is my 1st experience with a suppressor. The suppression is excellent. The push button ratchet is a bit awkward during suppressor removal, but is not a "deal breaker" for a recreational shooter.

    Coating began to come off after the first use and cleaning. Had to send it back to AAC for recoat.

    Thanks Travis!

  • Travis H8/22/2014

    First can for me. I am happy with this on my LWRC M6A5. First couple of clips I forgot to switch the gas block to suppressed, but it worked fine on either setting. I am extremely pleased with The Silencer Shop. You guys are first class, highly organized, and a pleasure to do business with.

    I had minimal poi shift. It's defiantly hearing safe I shoot it regularly with no ear protection. I have 1500 rds down it functions great. Although if you use the flash hider you do get a tuning fork sound not a problem for me.

    I've owned an AAC M4-2000 for many years and am very happy with the unit. I've run it on everything from 10.5" uppers through 20". Full-auto and semi. I also recently put it on a Tavor. Works very well. Extremely durable and good noise suppression. It does cause a lot of blow-back versus other designs but otherwise it is an excellent suppressor. It's handled everything I've thrown at it for 10 years and looks like it will for many more.

  • Chad5/21/2014

    Run this can on my ar15 and my bolt action 5.56. Works great on both. The only issue I have is that it's about 2-3 moa off at 100 yards on my bolt gun. For shoulder shots no problem. On my ar15 with eotech and nightvision it's a great setup. If you want to have a suppressor you can switch on and off guns this one is it.

  • MATTHEW4/24/2014

    The AAC M4-2000 was an easy choice for a multi-platform suppressor in 5.56 caliber. The versatility of the suppressor between countless weapons platforms allows for the user to simiply add an AAC 51 tooth muzzle device to any compatible rifle. This suppressor showed minimal POI shift once attached, and it's ratchet attachment method ensures a secure fit that won't back off under rapid fire use. AAC uses high quality materials and finish that don't deteriorate under high heat from full-auto use, yet it is still relatively lightweight at 17oz. I'm very happy with my M4-2000. From Rem. 700, to 10.5" SBR, to Mk12 SPR, this suppressor gets the job done!

  • Michael H.4/18/2014

    AAC makes an excellent can, great customer service everytime I've called or emailed I've received a quick response. Mounting system is fine and locks up tight or with use it will tighten up. POI shift is minimal, not as good as surefire but it's repeatable. Supresson is excellent for a 5.56. Silencer shop has been great to work with.

  • dclay10004/4/2014

    I have a blackout and use it on several of my rifles. I like the durability and ease of mounting. it does greatly increase back pressure in short barrel rifles. Over all I am very pleased with the design, durability ergonomics, ease of use and would recommend this can to any serious buyer. If you have a adjustable gas system it is even better!!
