It has wrench flats on the barrel to support torqueing during installation or adjustment. Forward Controls Design's KeyMo muzzle device is made from machined, 4140 heat-treated and QPC-coated steel bar stock for unbeatable durability. I was only expecting just for sico to change the retention spring in the asr. Compared to an A2 compensator, the KeyMo provides 15 to 20 better muzzle rise control. All i can say is wow! Sico went above and beyond for my warranty. The KEY-MO requires a Dead Air Key Mount muzzle brake or flash hider in addition to this adapter. We reserve the right to correct typographic, photographic and/or descriptive. If you have the ASR adapter in your Silencerco suppressor, you can choose the Key-Mo adapter for the ASR locking device, which is found on the Saker, Chrimera and other ASR equipped Silencerco models. Upon opening the box and looking at the warranty invoice and suppressor i noticed the can was refinished, a new updated asr mechanism was welded on, new end plate, and new baffles installed and welded. NOTE: Prices, specifications and availability are subject to change without notice. 3 weeks after sending the suppressor in i receive the can. Updated them on the ongoing problem and they gave me an rma for warranty service. New asr mount and still the problem persisted. Then to make sure we checked every possible problem that could cause it they sent me a new asr mount. Emailed sico about it and they helped trouble shoot which was a good temp fix. The silencer is mounted by lining up a grove on the KeyMo to a notch on the muzzle device. Both muzzle brakes and flash hiders are available and can be pin and welded if your project requires it. Had problems with the suppressor coming loose while shooting. For a more traditional, one-handed QD mounting system that locks up solid, the Dead Air KeyMo is hard to beat. Purchased this can back in 2015 so it had some wear and older features. Plenty of vids out there to help explain these systems too.Just got my sico specear 762 back from warranty. The taper style gives more (and shorter) muzzle device options and shorter overall length. With the long KeyMo muzzle devices you'll need to use the CGS QD Adapter. Others may in the future as well depending on design. 2A) The new version of the Dead Air KeyMo (the one without the extra material in front of the threads) in combination with the Key Micro brake works in the Helios QD without using the CGS QD Adapter that's included in the Helios QD kit. Cans like the CGS Helios QD requires an extension piece to use the ASR, Keymo and other mounts. And, as anyone with a direct thread can/adapter knows, it WILL spin off under use. Well, you can do it with SiCo cans, but you'd have to go direct thread (without positive lock/retention).

The Dead Air Xeno system is a good option as well. With the Keymo you can do that but not with the ASR because you need to lock it at the base of the silencer. The ASR and Keymo are good options but for me there are too many advantages of the taper style - size, weight, cost, etc. However, i just purchased another suppressor (Liberty Precision Anthem) and after doing a lot of research on them and mounting devices I’ve decided to switch over to the Rearden system and dedicate the Specwar cans to specific guns. I do use copper based anti-seize on the threads every so often to keep from locking up on the muzzle device. No issues with repeatability- I shoot monthly matches and just throw the can on and hit out to 1k yds no issues. I have several rifles set up with the ASR mounts since I have a Specwar 762 & 556k. You can secure your SilencerCo Saker, Omega, Hybrid, or Harvester Big Bore to each host firearm to replace the SilencerCo ASR QD mount.
