I continuously read that good suppressors seem to work in favor of greater precision in a rifle. I’ve only seen this phenomenon once in person, but I’ve seen an awful lot of pictures and read an awful lot of reports confirming this to think otherwise. However, as far as I know, all of what I’ve read has been concerning basically rack-grade barrels and some Noveske N4 barrels. Does anyone know if the same phenomenon would be true of attaching a suppressor to a precision rifle barrel?

I’m gonna try to see how better my rifle shoots with a can on it but I don’t think I would consider my rem700 a precision weapon. I definitely enjoy the quietness of subsonic ammo through it 
BAC i’ll let you know when I get back up to my buddies property in PA to zero in my scope.
As I understand it, the weight of the can reduces barrel whip. Thus the gain in accuracy.
I’ve never thrown my can on a precision set up. But I’ve seen my groups tighten up quite a bit on my regular barrels.
I will not put my suppressors on my personally owned precision rifles because I have experienced damage to the barrel crown on precision rifles at work. A minimal increase in accuracy versus a greater chance of damage to the crown just isn’t worth it to me.
Could you describe the nature of the damage to the crown on the rifle you used at work, and the can that caused it? I’m wondering if there’s a difference between rifles with muzzle devices (brakes, flash hiders, etc.) and those without.

Crud blown back from the suppressor would cause nicks and burrs on the muzzle causing a rifle that typically shot 1.5 MOA to shoot inconsistently 3-5 MOA. It was caused by a Surefire suppressor using a Surefire QD mount.
Interesting. Anyone else had their crown damaged from suppressor use?
I’ve read of this before. Maybe from usmc51…
It could be an issue with a specific caliber, can/mount design, or ammo selection, or even a specific barrel.
I’m not convince that it would be a problem for every precision set up at this point. 
You probably read my post under someone’s topic about the specific setup a while back. I would not want to mislead anyone into thinking it is a problem with all, or even “many,” precision suppressed rifles. It was just my experience that was enough to dissuade me from risking it on my personal precision rifles.
Absolutely. It’d be interesting to post this question in the Sniper forums to see if there’s any info available.
Perhaps its specific to the suppressor in question, since its not anything I have ever seen on a SR-25, or heard about in Mk11’s and Mk13’s
I was looking at my M4-1000 mount last night. It’s the phantom variant and thus has a relatively sharp edge where the bullet passes through… much similar in diameter to the crown. Anyway, after over a thousand rounds on this mount, I can’t see any errosion on that defined edge that covers the actual barrel crown.
The only suppressor I have ever heard that caused a negative effect on the muzzle or crown, was the Smigett suppressor from the now defunct company TL Guns.
The cause appeared to be that the first ( blast ) baffle was located extremely close to the crown.
My experience with countless other suppressor brands and many thousands of rounds has not produced negative issues with a weapons muzzle / crown.

My experience with this issue was on an SR-25.
