| whats the diameter of this brake? I'm planning on ordering a bushmaster lightweight barrel soon, and leaning towards one of these to put on it. If anyone has a pic of this setup id greatly appreciate seeing it. |
If it's a matter of perception or felt recoil/muzzle climb, maybe you are insensitive  Speaking for myself, I rarely notice the recoil and muzzle climb even in full auto, the addition of a brake usually doesn't appear or feel like it's dampening what little there is to begin with. The one exception I have experiences with is the HK51. Without a brake/blast enhancer, the recoil is very noticeable, but then we're talking about a 30 cal weapon firing from a barrel that's 8" too short

It works very well in all calibers as a competition muzzle brake, if that is your application. It does raise a noticable dust signature for prone application. The original poster never stated his application on a LW barrel. |
Assuming it is not an LE or .MIL, the MSTN brake is one of the best on the market. I have only added the conditional (LE/MIL) because of the dust signature. That can be addressed with some trade-offs. |
(LE/MIL) ? oh yea what about indexing i keep seeing this but not sure what indexing means? is this something i can do or will i have to send it in and have it done? |

I have been amazed by the effectiveness of my MSTN QC brake at eliminating recoil and muzzle rise. However, the OPS 2 port brake is also very effective in controlling muzzle rise even if it is less effective at managing recoil. I've been very pleased with it's performance on this rifle.

Our brake is 0.95" diameter, tapered at the rear to 0.745". My wife has an affinity for 16" pencil barrels for 3-gun (the old Colt 1-7 twist ones), and she uses a MSTN QC brake on those. It doesn't look too bad and she really ticks off the uber-tac guys when she beats them on the long range targets. The dust signature was a trade-off in our original design. Several other designs we tried had less, but did not look symmetrical on the muzzle so our test marketing said they would not be as well received. One of the prototypes went to a Marine armorer who like it enough to recommend the current model to Force Recon. There are a lot of them being used unofficially right now. We have continued to work on various designs and will likely come out with a new one early in 2007. (No advance looks, either. When we settle on the final design it will be out shortly thereafter.) Our core criteria will still be met. Comfortable to shoot with earplugs only, muffs not a necessity. Neutral muzzle during full-auto fire, no nosediving. Legal dimensions for Limited/Tactical 3-Gun rules. No reduction in accuracy. Maybe not for everyone, but a lot of folks seem to like them. |

I don't have a pic, but I will get one taken and post it. In normal daylight, flash is not perceptible. At dusk there are two halo arcs, one at each side of the brake, 6-8" outside of the rear expansion chamber. Kind of like the outside bands on the XM Radio logo. The intensity of the halo depends on the powder. Flash retardant powders are almost transparent. Others are a bit brighter. In full dark the halo is easy to see but there is no fireball with decent ammo. These are not flash hiders, but a lot of them are being used in situations where one might have benefit. They are used because they offer more sight stability and allow shooters to observe their bullet strikes. Easiest way to contact either me or Wes is via email. (I can answer 50 emails in the space of one phone call). [email protected] or [email protected] |
Didnt mean to bash the product...that was a poorly worded response on my part. What I meant to imply was that it was not that quiet, in my personal experience, compared to other brakes and IMO not as effective as a Cooley, an F2 or a Benny Hill brake...all of which I own or have owned until just a few months ago. I compared all of these and a QC brake this spring. It was a bit quieter, but at too much of a trade off in performance. I dont know of any 3 Gun shooters using this brake in Texas (although I am sure there are some, just have not seen them) and I have never seen this brake on the winners rifle at RM3Gun, the Nats, SMM3G, Tx State 3 Gun, DPMS...well you get the idea. It all depends on your application. Each has its role. The QC is good, but not in my opinion close to the best. YMMV B |
Tag for pics. |
PaulE was being very modesty in his post. As to IPSC 3-gun, I was personally embarrassed in the Texas '93 3-Gun Teaxas Champonship (I am a TX resident) , when Benny Hill smoked all the 5.56MM weapons with his new at the time, SR25. This was not just the difference beween major or minor scoring. He flat out shot everyone. period with a 7.62N weapon. For the pure sport, there maybe and are probably better brakes compared to the current MSTN QCB. The current MSTN brake is the best for sport AND real world. This is based on a non-supperssed weaon requirement. |
I'd like to see some testimonials from "real world" users of these. |
I have used a bunch of QC comps on my builds and they are VERY VERY effective as a muzzle brake. No good muzzle brake is going to be quiet, so just give up on that idea and be happy with how it WORKS!
