Once it's up to snuff I want 2. One in 1/2-28 and another in 5/8-24. Keep up the good work clobb!

I thank you kindly for your support, but I have no plans to produce them, I leave that to the real experts in muzzle device design.

Also, regarding the 5/8x24 (AR10, etc). This would require a whole new round of calculations, design and testing for a rifle platform I don't have. To get it to work properly, it has to be re-designed almost from the ground up to perform for the cartridge the rifle is chambered for.

Put another 300 rounds through it today.

The Good: The revisions fixed the over-compensation issue. Rapid fire was very fun, and it was easy to stay on target. Recoil felt the same.

The not so good: It's still very loud, with heavy muzzle blast and flash. I feel like this is not a great device for my 10.25" barrel. My rifle tends to be a fire breather at the best of times, and this little device just adds to that. I would really like to try it on a 14.5 or 16 inch barrel. I think the experience would be much more pleasant.

That being said, it was quite fast, allowing me to keep most of my shots within the 9 and 10 ring of a B27 target when firing it as fast as I could pull the trigger. I'm not a great shot, but I'm happy with it. I can't do this with any other muzzle device I've tried on this rifle. Shooting the gongs at distance was fun.:)

Click on the photos for a video. Testing was done standing with 5 mags, 24 rounds (one of my mags only holds four rounds), speed reloads from a belt and dump pouch. Distance was 15 yards.

1st video:


2nd video (please note that I was not shooting from the angle this video was taken, I was in front of the target which was aligned safely down range):
 
Wow, those vids are very impressive. Seems like the device really works...I bet performance would be even better with a standard barrel length.

Cool beans.

So what documentation have you been reading, exactly? I'm curious, now!

It's very heavy reading of text books mostly, and much of it would bore many members here. I'm very embarrassed to admit it, but I still don't understand it 99.9% of it.

To build these devices correctly you really need a lot of education in that technical field and the proper testing equipment. You need high speed cameras, devices to measure recoil, and the ability to model gas flow through the device by computer and a bunch of other stuff.

Hobbyists like me don't have the technical knowledge or equipment, so we have to rely mostly on gut instinct and trial and error to get it kinda right. Then most, including me, are copying things that were done 60 years ago. There's only so many ways to skin a cat when it comes to this game.

It's embarrassing really, compared to what the professionals can do.
 
^^I sent Chuck Norris a Clobb Comp. When he opened the package his house was instantly destroyed. It just couldn't contain that level of awesome.:D


I'm sending the device off to another CGN member to test on his 14.5" AR. He's generously giving his time to test it and report back in this thread with his impressions.

What text books do you read? Fluid mecahnics?

The stuff I've been reading is more specific to the subject matter, so yes fluid mechanics is part of it, but not the only part.

I'll send you a PM rather than bore people in this thread.

No! or send one my way too? I'd like to know where to start with this as well clobb, other than the LCF.

I'm a big fan of people stepping up to this stuff, and would like to try it myself eventually.

There are no books, manuals or papers that will give you a "how to" manual on building flash hiders or muzzle brakes. I was warned about this a long time ago by a friend of mine.:redface:

What is available is very heavy technical reading and most people will find it very boring (I was warned about this too). If you have a sleeping disorder, this is the cure.

If you just have to read something and want to start somewhere you could try "Gun Muzzle Blast and Flash" by G. Klingenberg. It's a reference book that covers many aspects of transitional ballistics.
 
^^Thanks. Another board member has the comp right now and will post his review when he has some time. I wanted to have someone who has an AR with a longer barrel than I or CarbineOne to give it a thorough testing.
