I can't see any muzzle device affecting accuracy. It could change poi, however unless it was constantly changing between shots the accuracy would not be affected.

I was told by a couple of different gunsmiths ,that putting an 11 degree campher on the muzzle of the barrel will effect the accuracy a lot more than any muzzle device that will be installed on the end of the barrel.

Bullshit!
The angle or shape of the crown has absolutely NO effect on the bullet.
As long as the crown is square to the bore,,,,nothing else matters.
The Army tested crowns in depth, including high speed photos, ans found NO effect on the bullet.
The Army found that the gases exited the muzzle at 11* no matter what the crown looked like.

Also even if a crown was important, the muzzle device does not change the crown on the barrel.

Just an observation here, but if muzzle shape/device had that much effect on the bullet, POI, energy, etc., I'm pretty sure the military wouldn't be using anything on muzzles of their sniper weapons. A few months ago, a young man recorded the longest confirmed kill EVER. And he did it twice in a matter of 5 minutes.

Either that, or the effect is so slight, it's not worth the detrimental effects of not using a muzzle device. Needless to say, I'm thinking none of us will ever make an important enough shot to eclipse a live save shot like the young soldier did in Afghanistan.

There is a point at which you can worry too much about the small stuff that no one else worries about. Yes?

So...The 11 degree campher is just hype

And the extra coin I spent on the last six barrels is just an unnessary procedure.
Hate to think that I wasted money on match barrels and didn't get everything out of the build.

IMO the 11* crown is a good thing and care is taken not to damage it.Just my .02

Mike, the 11* crown is as good as any,it's just not any better.
you have to have some type of crown, on tgt rifles I do put 11*, but on hunting rifles, and sd( self defence) guns I put a crown that protects the muzzle better. Either a rounded "traditional" crown, or a recessed "flat" crown.

Here's the last one I did for myself

a little hard to see the profile and chamfer of the bore

Ok and now back to the original question...I'm a big fan of the PRI brakes {have 3}.
Now to stir the pot a little, Bought a Levang linear comp as an Xmas present to myself and used it yesterday. Im pleased ,it throws flames and directs the blast downstream !
I wanted a Noveske KX3 the flaming pig brake but it was never in stock when I had money. I also have been looking at the *See Site News* Weaponery Dragon's Head muzzle.

I'll take what Primary Weapons Systems has to offer over anything else. As of this post, I am using the FSC30 compensator with great results but my PWS Precision Rifle Compensator will arrive sometime this week and I've read good things about it. A good compensator will HELP your accuracy and allow for maintaining your POA more easily.

What about this
JP Tactical Compensator Black .308 cal .875 barrel
I kinda had my eye on this one. Any thoughts?? Is there a better one?

KillShot · « **Reply #27 on:** February 12, 2012, 05:11:03 AM »

JP makes some good stuff but I've always considered them more of a 3 gun company.

What is the intended use of this rifle; run & gun or precision/benchrest shooting?
