I recently had the factory flash hider replaced on a fairly new Sig 551–A1 upper - the flash hider that comes on them is hideous.
I asked them not to use a crush washer in my instructions (even included a copy of this page here http://www.robertrtg.com/sig556flashhider.html) but it looks like the threads were not deep enough so they used one anyways. I have no problem with this except the crush washer that they used is bright silver and really stands out. I've never seen a silver crush washer before and the ones on my ARs are black. The whole purpose of this exercise was to try to get closer to the real SIG 551 look. Also it looks like they scuffed the barrel immediately behind the flash hider. It was not like this when I sent it to them and there were no perforations in the return shipping box and no other parts inside the box. It's fairly obvious it happened during the FH removal process. I probably could've gotten the FH off with less damage myself and thus the reason for spending the money (40 + shipping both ways) on a professional job. The finish on the barrel looks like nitride so these are pretty hard to scratch. I realize I will be blasted for being concerned with cosmetics - fair enough. I am not naming names and just want to get some advice! 
EDIT: OK what appeared to be a scuff was aluminum from their barrel clamps and came off rubbing it with household ammonia (thanks for the tip on that). CLP wouldn't take it off. I am good on that issue and it's not a scuff in the finish. Here's my letter that accompanied my upper. It states "no crush/peel washer". The original above post states "no crush washer" but I in fact requested no peel/crush washer.

That isn't a crush washer. Crush washers are black.
That is a peel washer. Peel washers are silver and were standard prior to crush washers. It has nothing to do with thread depth. They are used to time the flash hider correctly. Go look at a M 16 A2 and you will see. |

That may just be aluminum that rubbed off on your barrel from the barrel vice jaws. Try to clean it off.
Why did you send it out for FH replacement? Anyone can do that at home with no specialized tools. |

Peel washers were standard an most early to mid AR15-A2's. The A2 flash hider has to be timed, you heat the peel washer and use the slivers as shims to get correct orientation of the top slot in the Flash hider.
If that is not what you wanted or asked for, Take it up with the builder asap. |

Yep, looks like a peel washer to me. I just recently put one on myself.
You should look into doing this level of work yourself. It's not hard and if cosmetics is a concern you can get exactly what you want. edit: I don't think it's any big deal one way or the other being concerned with how your gun looks. It's your gun. I put an A1 flash hider on my carbine with a lock washer because I don't care about dust if I fire prone and I think the lock washer looks cool on a pencil barrel.

You can’t work a ¾” wrench? And they did follow your instructions, no crush washer was used…that’s either a peel washer or a set of SS shims that they had to use to time the FH… |

Yes - I gave it a whirl using 2 pieces of 2x4 pine with a hole bored between the 2 halves and a layer of hockey tape around the barrel. The original FH was on there good and wouldn't budge. |

I hear some of these here, hardwares stores, now carry fancy cans, with paint inside em....
And get this, that there can, done sprays it out, and onto things.......
They did you a favor, you said no crush washer, OK, then the flash hider goes on until its tight, whether its positioned correctly or not. Once you start telling a professional how to do his job, live with the results you asked for, as you said, its a "Collectors" item, so, it doesn't matter where the flash hider is, if its sitting in a safe.

Ironically, a crush washer is what you did want. It would be black. The guy did an adequate job according to your instructions. This was a case of the customer not knowing what he wanted. The scratch will likely dissolve off. The smith should've cleaned that up.

From your post I gather that what you really wanted was for someone to mount your barrel in a lathe and time the flash hider by cutting back the shoulder so it could be properly timed without the use of a washer at all…. If that’s the case then you need to recognize that it was your ignorance and not the gunsmith’s that left you unsatisfied. Other than leaving a little aluminum on your finish the gunsmith gave you the job you asked for. Plus, that kind of work isn’t common and is extremely expensive. |

Aloha, Mark PS.....maybe the terms were confused btw: "split washer" and "crush washer?" Like the washers found on the old SP1s. These are split washers.

I said "no crush/peel washer". That is not what you said in your first post. Take some perms blue and black it out if it bugs you....or get a wrench nd take it off. It's a 60 second job to remove it. |

Get a wrench and take the flash hider off. Then put it back on and see if you run out of threads before it butts up against the thread shoulder. If not, then have that much bobbed off the end of the threaded part of the barrel. Be aware that the barrel crown has a critical effect on accuracy so have someone you trust do that work.

I requested "no crush/peel washer" but wouldn't have minded if they used something blackened or park'd like you see on 99% of AR rifles. This bright silver thing stands out - don't much like it. If they'd of called and mentioned this issue I would have offered my preference for a normal dark one.
I have the scuff mark soaking in CLP right now and will report back. I expect it's aluminum and hopefully it'll come off. |

I don't mind that one was needed, but really wish they'd have used a parked or blackened crush washer that would have blended in more.
