Title: Too much concussive blast from an A2 flash hider?
Post by: Big Frank on March 29, 2025, 08:26:43 AM
Are you bothered by too much concussive blast from an A2 flash hider? Me neither! But It must be a problem for some people. At least Strike Industries thinks that it is. Or wants us to think it is. This could possibly help if you're standing shoulder to shoulder at an indoor range, or have other limited application, I guess. If you think this is something useful, and not a solution to a non-existent problem, act now. The Strike Blast Shield for A2 Birdcage Flash Hider is Early Bird Special priced at $75. The MSRP is $99.95 and they'll be going up soon.

I'm not bothered by the noise or flash, and wouldn't use that thing....but I do like a linear comp for slim-line appearance.
My favorite was made by a guy in AZ. It's not much larger in diameter than the barrel and has forward-facing ports. Sadly the guy is no longer in business and I can't find anything similar..... I knew I should've ordered several.

Since I don't have a sound suppressor, I'll settle for a flash suppressor or a compensator. But never a muzzle brake, and thus, no need to cover it up to protect others from the excessive muzzle blast. I've often wondered if linear comps actually work as compensators or not. I don't see how they could really do much if all the gas is going forward. A bare muzzle does that too and doesn't have a compensating effect. Other than adding weight and length to the barrel, I don't see how the ones I've seen can have an effect.

you can get a saker asr 556k kit ( with muzzle device)  for about 800+ tax stamp.


its a pretty good can you can get for about $1000.   not cheap, but its way more affordable than other options.

e forms are about 1 month right now.

I would like to pick up a  9mm can for a Ruger PCC with a binary switch on it, but we are selling our house to downsize so no new toys for a while.
Thanks for the info.

I need a can that's full-auto rated for .50 BMG.

In my dreams. ;)

If i wanted a can for 9mm pcc  i would get a mutli cal can.   cans made for 9mm pistol have a nielsen device on them.  you dont need that with a pcc.

I know what a Nielsen device is but can't always remember it's called that. But I can remember the word "booster" when I forget. Or "that piston thing" if I'm having a really bad brain day. :)

The only difference between a compensator and a muzzle brake is the name. They both redirect gases to change recoil. And they both are very loud. I have compensators that ported on the top to control muzzle rise, and I have compensators that have both top and side ports that control both muzzle rise and the force driven back toward the shooter.  When shooting bullseye on a tight line, nobody wants to be next to the shooter with a compensator.

Compensators are supposed to reduce muzzle rise (vertical movement), brakes are supposed to reduce recoil (horizontal movement), and flash suppressors are supposed to reduce flash. But many muzzle devices regardless of name do two, or all three functions, to one degree or another. It doesn't help that manufacturers use the wrong terminology half of the time, including calling muzzle brakes, muzzle breaks. I don't want a broken muzzle, and don't trust anyone who doesn't even know what it's called to scientifically design and test a muzzle brake.

P.S. Mag-Na-Porting is an effective means of reducing perceived recoil, without increasing noise. The Mag-Na-Brake, on the other hand is the opposite of a silencer, it's a loudener. I don't know of any brakes that aren't loud.

Since the end of photobucket usability, I have yet to succeed at posting photos, so I rely on my soso descriptive verse.

I have an STI Eagle 5.5" in 45 ACP. It has a Schumann Hybrid comp.  If you aren't familiar with these, moving from breech to muzzle, there are four round ports at 1200, then three oval cuts that run across the barrel at 1200, and at the muzzle there are five more ports that encircle the barrel from 0300 to 0900.

When tuning loads I like to shoot in a dark range or outside at dusk. When all is right the only thing exiting the ports and muzzle is smoke. No flash and no burning embers. In just the right light during the day I have had observers say it looks like a steam locomotive coming down the tracks as it puffs smoke. Others just complain about how loud it is, and one bullseye shooter, standing next to me in an undivided range talked about the concussive pulse hitting him in the chest.  Me, I don't notice the noise is any louder than my 1911 or .357 wheel guns, but I sure do like that there is very little muzzle rise or felt recoil.

I think I had a Photobucket account but didn't use it. My Google Photos account is linked to my phone and computer. When I take pictures on my phone, it updates my account online. Then I click the shortcut on my desktop to go there and download them as a zip file. I can unzip the whole folder and edit them one at a time. I take big 4K pictures then cut them down to less than 30%. If something is WAY off center, I can crop it first, then make it whatever size I want. But I hardly ever do that. I used to make my pics 900 pixels wide, but 1200 pixels is still a small enough file to post here most of the time, so I use that size. 

I knew the Schumann Hybrid Comps had a row of ports down the barrel, and ribbed barrels with the ports in the rib that fit in a groove milled down the middle of the slide. At least I thought that was it, but I see they make threaded versions of the barrels you can screw a comp onto. I guess what I was more familiar with was just a Hybrid barrel with a rib and holes, not a Hybrid Comp. I found this picture online and it sounds yours has even more ports, Mike. I always wondered what having such big holes going that far back did to velocity. Not that it matters when you're target shooting with a .45.
