Zero keymo adapter11/27/2023 He mentioned they were unhappy with their cans and had ~2.5-3moa shifts on them. All mainstream manufacturers nowadays would get the same results using that test fixture.Ī swat cop from arizona approached me at NTOA and said he was part of a larger city team there with something like 45 or 50 surefire cans. They hang their hat on a test rig that is a bench rifle on a sled with a super fat barrel that eliminates all deflection and harmonics. That one company that I won't call out directly (OK, it's Surefire) is probably the worst for this. When manufacturers state that they have zero impact shift, that's just their marketing team lying to you. It's very much like a good muzzle crown.Īnyway, long answer is that your repeatability on a given rifle will be very good with the large taper alignment system of the KeyMount design, and each rifle will exhibit a different behavior that is unique that rifle. As it leaves the barrel and goes through the muzzle device, forces from the gasses that accelerate around from behind the bullet can cause an unequal push on it if the device isn't designed correctly. ![]() Precision in your group size is where having a muzzle device with symmetrical features can be important. The rifle just had a crazy harmonic with the load and barrel they designed their system around. Keeping the same KeyMount flash hider on the rifle, we could place another suppressor on that had a different mass and the group dropped to 1 MOA. We were seeing a full 8 MOA group size with one suppressor. When I was working with Tracking Point on getting suppressors to work with their system (back before they fell out of bed), we found that one of their rifles had massive harmonic issues with one of their loads. ![]() The exception (that's outside the manufacturers control) is that adding anything to a barrel can cause harmonic issues that are unique to that barrel. ![]() Precision should remain the same or improve. The good part is that when you put it back on that barrel it will do the same thing for that ammo. You'll have to note what happens on that rifle, as it may not be the same for another due to the reasons above. The important thing is that when putting a suppressor on a KeyMount muzzle device, it's very repeatable. Putting the suppressor on adds 0.5 MOA after that. Just putting a brake on my 6.5 CM Bergara B14 will cause a 2 MOA shift down. A long pencil barrel can have a big impact on that POI shift. The biggest impact on accuracy will be your barrel, its stiffness, and the effect of harmonics. Note: As I talk about accuracy, the true definition is the difference in point of impact from point of aim. ![]() The features on KeyMount muzzle devices are designed to maintain the accuracy of the host weapon by having a very large taper alignment surface and internal features that won't adversely push the bullet around. pistol suppressors) and the micro muzzle devices are meant to fit in either, while the longer existing ones may not fit in smaller pistol blast chambers like the Ghost handgun suppressor. The KeyMo and KeyMicro are adapters that are differentiated by the thread socket (rifle vs. Also, the taper on the can and mount provide significant accuracy advantages over other mounting systems and the one handed positive ratcheting system is easy to use and cool as hell.I think you may be overthinking it. Your silencer is now compatible with the Dead Air Key Brake and Flash Hider – giving you the best mounting system in the industry.Īdvantages over other systems are that you do not have to access the collar to lock/unlock the mount so it can be used on a 10" barrel under a 14" large diameter rail, for instance. Simply unscrew your existing mount, and thread the Key-Mo on. We’ve developed the Key-Mo™ to give your SilencerCo Omega and Saker a much-needed upgrade. If you’re one of the many owners of a SilencerCo® Saker, Hybrid, or Omega and have ever longed for a simpler and more reliable mount, your salvation is here.
