Lotsa Magpul products on your carbine, eh? :D

Yeah, I drink the Kool Aid. I also wanted to keep it as light as possible.

I wonder what it would effect if you made the ports smaller but keep the ports the same size for the four on the muzzle end.

I have some ideas for improvements, but the thing works so well during rapid fire I hesitate to mess with it. It needs more testing and some non-biased evaluation.
 
Nice comp.
Clobbersauras came a long way.
Apparently, unlike the big majority of the wannabe designers on this board,
he does his homework (some reasearch and reading).
Good luck.
 
^^^Thank you for the kind words Doc. Coming from you, they mean a lot to me.

I'm just a baby when it comes to my understanding of this stuff. I don't even consider myself good enough to be a wannabe. I'm still trying to learn, especially the mathematics portions of this discipline.

Yeah. Praise goes razor thin with him. :D
 
Looks like a nice stainless barbeque after a big stack of steaks! Outstanding work Clobb, did you get it this good on the first try, or is there a pile of bastard-clobb's in the trash?

Thank you. No, this is the first. I don't have enough cash to have a thousand dollars tied up in prototypes.
It isn't perfect. It's loud and it puts out a lot of blast. I'm pleased with the first attempt though.

I just sent the comp off to CGN member CarbineOne. He agreed to test it in his next round of muzzle brake and comp tests, where he actually mounts a camera to his rifle to give an impression of muzzle rise and recoil.

I'm interested to see what results he comes back with, and a little nervous too.:redface:

now the $1000 question. who is going to start building these?
i want one.
Clobb, good work! I wish I had half the brain in my head (not to mention the balls) to put money on the line like that a design something of my own.
I'm interested to see CarbineOnes review, any sneak peeks to what rifles/ barrel lengths you will be using?
From Clobb's view it sounds like over-compensation might be an issue with the longer barrels. ("Actually, in singles the comp seemed to push the rifle slightly lower than center")
Never-the-less still interested, and once again good work!

Thanks for the compliments.:)

I want to wait and see what CarbineOne's tests come back with before I move forward and possibly make changes. In his last tests he used an 11.5 inch barrel. I don't know how his review is going to go, he could come back and post that it's a piece of garbage and the only thing it's good for is as a paperweight.:redface:

I also want to spend some more time shooting with it and try to determine how I want to go about making changes. There are a few things I can do about the over-compensation issue (different ways to skin the cat, so to speak), but I'm not sure I want to make changes in that aspect as it's only a minor issue when firing singles. The problem seems to go away when you start any type of rapid fire.

I have no plans right now to produce it.
 
Some bad news in the midst of all the good news tonight...

Well guys, CarbineOne got back to me with a review of my comp that I sent him for testing. It wasn't what I hoped for, but unbiased review is a vital part of the design process that leads to improvement and gets you closer to perfection, which for any designer, hobbyist or not, is the ultimate goal.

Here is the review I received from CarbinOne via PM tonight. I've printed it here, unaltered, with his permission. Though I did not experience some of the extreme results that he did, I fully trust his opinions and experiences and want to extend many thanks to him for testing my comp.

Stay tuned for version 2 in a couple of months...

Yes indeed *****, I gave it about 50 rounds Sunday night after filming for my muzzle brake test 2.0. Ideally, I would have run it at a range session with drills, but for reasons stated below I decided to nix that idea.

The Good
+ Good recoil reduction
+ Compact
+ Looks good!

The Bad
- The brightest and longest muzzle flash; Perhaps exacerbated by the fact that it was filmed in an indoor range (you wouldn't see any flash outdoors in daylight), the muzzle blast was very bright, and did not dissipate as quickly as some of the other devices. Normally not a problem, but in this instance the flash was large/long enough that I completely lost sight of the target at 15 yards. As you'll see in the video, it ended up being worse than having no muzzle device at all. During the 5 round speed string, the flash was so overwhelming I could only guesstimate where my POA was in relation to the target. I would have had to slow down in order to visually reacquire my target.

- Overcompensation; My point of aim was pushed completely below the target paper. I would estimate it dropped my POA by 2 feet at 15yds. Observers said the muzzle drop was very noticeable, and they agreed with my findings when they fired it as well. Unlikely a problem with a bench gun, but those who run and gun (like myself) would find it a hindrance in target acquisition. I would actually go so far as to say that the reduction in recoil offered by the brake are negated by the overcompensation, resulting in only a negligible net speed gain in target engagements.

*It also has the side effect that I couldn't properly judge how much recoil reduction the brake provided, as it did not really move like I would have expected a rifle to.

- Concussion; The most 'blasty' of all the brakes I tested in this panel. One observer standing approx. 15 feet to the right of the gun mentioned it was the only brake he could feel in his chest from that position.


Unfortunately not the best of news, but I'm only providing all the data I could scavenge in those 100ish rounds experience with your device.

Two things that I think may help with the flash problem;
-Increasing the diameter of the ports
-Increasing the inner diameter of the brake

I'd also suggest machining an additional row of ports at 10o'clock and 4o'clock to reduce the overall compensation, while possibly providing increase braking. It shouldn't increase the dust signature much, if at all.

Lastly, thanks for taking the time and effort to design and machine a brake and sending it to me for testing. I look forward to new revisions of the brake! Let me know if you have any other cool things you'd like me to test

I'll also let you know when the editing of the video is complete (might be awhile, now that I have 3 times as much video to cut!).

Regards,
CarbineOne
