What does your Remington 700 SPS Tactical AAC-SD muzzle look like?

[kopje]

Hi Folks,

I just got a 700 SPS Tactical AAC-SD. However the muzzle of the rifle is pretty rough. It looks like it was not processed and polished. I have not seen a similar one by googling. Do any of your AAC-SD muzzle look like this:


Thanks!

Mine doesn't look like that at all. Sorry, man.

Is that a new rifle?
It looks to me like it's been fired quite a bit with some sort of muzzle device attached.
Mine was faced (machined) flat with a pretty nice surface finish (smooth) and an even phosphate (Parkerized) treatment.

My thoughts exactly. That rifle has been fired before.

Thanks guys.
[MENTION=97829]delixe[/MENTION], it is a used rifle, and the original owner claims that it has only 10 shots so far. Overall the rifle looks pretty new. I am asking him whether he has used a muzzle brake before.

If it is new unfired then ya you got a problem but if its used... yes, it looks like mine after shooting with a comp on the muzzle for 50-100 rounds. Carbon builds up and the pattern is the mirror image of your rifling.

Guys thanks a lot for your opinions.

I got this rifle used. However the original owner claims that he bought it new and has shot only 10 rounds through it - the rifle does look like new and especially from the minimal wear of the bolt and the receiver. I just contacted with him, and he said he never installed any muzzle device on it before.

If it is carbon built from shooting, it should be cleaned up by solvent. I will try some solvent this evening. Initial look and scratch using my nail it looks like metal...

OP............do you have a AAC 762-SDN-6 yet?

Is there something one is supposed to do it avoid this? Should I expect it to happen to my rifle? I just put a comp on. Does it degrade accuracy? Can it be removed?

A break should have no effect on accuracy as long as it's torqued on decently.

I'm specifically asking about the build-up of carbon under the break, like the OP has shown. Is that an issue? Does anything need to be done to avoid/address it?

Another 'only had about a dozen rounds through it!' That actually means about a dozen boxes! Scrub, scrub, scrub with some bore cleaner and an old toothbrush. While you're at it, scrub the bolt face and extractor. I'll bet it's dirty too.

I doubt its proper cleaning etiquette but I use something hard to break it loose. Just don’t use anything hard enough to damage the steel... hard plastic and/or wood pop sickle sticks work.

Does it degrade accuracy? Can it be removed?

No, I have not noticed it degrading accuracy, but it doesn't look terribly nice on a otherwise clean rifle.
