Lumpy dont do muzzle brakes and Lumpy aint going to be able to own an Ops Inc suppressor any time soon......therefore Lumpy dont do Ops Inc muzzle brakes.

OUr new QC, "Quiet Control" brakes were designed to do several things:

1-   Be neutral. No muzzle jump or nosedive, reduced recoil, minimized walking
2-   Be quiet. No muffs or double plugging, comfortable with earplugs only, even to bystanders.
3-   Be accurate. Minimal POI shift, reduced gas turbulence at muzzle
4-   Be as small and light as possible, while meeting 1, 2, & 3.

While these are all assets to a competition brake, they are also important for fighting weapons.  We did extensive full-auto testing during the prototyping phase and the QC is one of, if not the most controllable muzzle devices we have seen. The 6.8 version tames the 6.8SPC full-auto, not a trivial task.

Putting as many rounds ON TARGET as quickly as possible wins matches, including the two-way ones where the targets shoot back.  A growing number of military units have noticed, and are doing their own testing on these without solicitation from us.  In the competition world, we saw our guy, Taran Butler, win every match he entered this year, all using the QC Brake (on MSTN-built uppers).  We could not have a better advertisement than that.

We tested a lot of different brakes before we started this.  The Miculek was one of many.  It has to be clocked to keep the muzzle from walking and tends to over comp (nose dive) in multi-shot strings.  Also, noticed the first baffle sustained considerable gas erosion after only 250-300 rounds, so I am not sure of the material, but appears to be a free-machining steel of some sort.  The QC is machined from 304 SS. It's a lot harder and holds up to the gas much better.  

The QC is quieter behind and to the sides back of the muzzle than similar brakes.  It does not reduce or suppress the sound generated, but does eliminate most of the concussion associated with most efficient muzzle brakes.  The sound has to go somewhere. A lot of brakes send it back to the shooter and any bystanders.  The QC sends the sound radially forward, away from anyone behind the firing line.

dB ratings tests are fultile, in my experience.  A controlled test can be set up to provide virtually any result you want.  What matters is what you actually hear.  I can shoot a lot of firearms on open range without protection in relative comfort (I don't anymore, but there were darn few concerned with hearing protection when I started shooting).  Those same firearms, shot on a covered range can make your ears bleed.  I would not shoot an AR with a Y-comp without double plugging (plugs and muffs). Same with a Miculek or Cooley brake. Even out in the open they are tough on shooters and those around them.  The QC is quieter in the same situations.  I have seen RO's turn away from some shooters, anticipating the concussive blast, then react with surprise when the QC came up and didn't take their heads off.  I wouldn't say it's quieter than a plain muzzle from behind the gun, but the shooting is over a lot sooner!
