Waaay out west.
I love muzzle devices, comps, brakes and flash hiders. I'm fascinated by them, so when Dlask came out with their new XB5, I couldn't wait to test it. It looks similar to the Levang linear compensator but it's internal and external construction is quite different. It's designed to force gas and blast forward, away from the shooter.

It's internal structure is very cool! (Sorry I'm a geek for this stuff, can't help it:redface:). They made the six ports slightly angled, to create a kind of rotation of the ports around the bore. It's so slight I almost didn't notice it so I stuck some straws in there to illustrate it:

I've never seen this done on a muzzle device before and it's cool because, in theory, it should more efficiently strip gas away from the bullet as it leaves the muzzle. This should help stabilize the bullet during flight and improve accuracy. They also recessed the muzzle which also helps create a preferential flow of gas away from the path of the bullet.

I really wanted to save this device for a 22lr target rifle I have coming but it looked so friggen cool I had to try it on my AR. Here are some more pics and a video:

It worked great, there was noticeably less blast and recoil was light. It's important to note that I don't recommend using it for short barreled rifles as you are likely to burn through the device very fast. I shot about 150 rounds through it then put my trusty A2 Flash Hider back on. AR target rifles, and rimfire rifles is where the XB5 should really shine. I'd love to try it on a 16 inch recce type rifle, I think it would be the cats ass in that application.

Cheers! Clobb
 
That swirl effect must put some kind of torque onto the rifle. Is the swirl rotating in the same direction as the projectile or against it?

To be honest I didn't notice any difference in torque when shooting some drills, but it's a good question to ask. The ports are kinda oriented in the same direction as the rotation of the projectile (I think), and more importantly same direction as the gas flow.
 
Got an 300 round belt feed 22 that is just begging to get this boy slapped on. Guess I will have to bug big Joe next week when I see him.
Luv the spitting fire balls Clobbersauras & again great review:rockOn:
Under your nick name should be changed to say K.M.B. (King of the Muzzle Brakes) ;)

LOL! Muzzle devices are a sickness I have.:redface:


Did you post a review of your belt-fed in the Rimfire section? I have to see that thing!

Can you do a side by side with an XB1? Do you have overall length for the XB1 and XB5 and what the additional length would be once screwed onto the barrel?

Might be a newb type question, but do .22 calibre muzzle brakes and flash hider generally as a rule fit 223?

I know the XB5 is considerably thinner than the XB1 and lighter.
Length, not sure but here is a photo of the XB1 I just installed on my AR.

Sorry I don't have an XB1 to compare it to.

I don't recommend using muzzle brakes on 22lrs. Bullet stabilizers like the XB5 etc or bloop tubes are good to use on 22lrs, but who wants to be covered in the toxic powder residue and lead particulate used in most s**tty .22lr ammo when using a brake?
 
.22 rimfire projectiles have the same diameter as .223 ammo, 5.56mm. My question would be is it safe to use a muzzle brake designed for a rimfire cartridge in a centerfire rifle. I would like to try one too on my Norc M4.

It should be fine depending on what type of material they used to make the brake. Erosion on the brake will be greatly accelerated with .223/5.56. What brake is it?

At least two of us have used them on AR's and lived to tell the tale.
I called Dlask and confirmed it is fine to use for .223. The barrel does get
very hot, other than that no issues with a couple hundred rounds so far.
