I just bought a Bushy postban M-4 carbine and noticed some big differences in machining between it and my LEO M-4 which I purchased a year ago.  To start with, the barrel on the post ban has machining marks which look like ribs down the length of it and I also notice machined grooves on the exposed side of the bolt carrier.  I'm not sure any of this poor machine work will affect longevity or performance however, as I inspect my LEO Bushy M-4 I am hard pressed to find any of this rough work on the barrel or bolt carrier.  In fact, the LEO gun has a smooth barrel exterior and bolt carrier which is void of any type of imperfection.  I am now wondering if this is an exception to the rule or is it the rule?  I've always had good luck with Bushmasters in the past and am wondering if I just bought one that was turned out on a Friday when someone in the factory was in a hurry to get to the local tavern.

How does it function?

Most AR owners are more interested in whether it shoots reliably and accurately and not so much the fit and finish.

What not concerned with looks along with accuracy. I beg to differ when you spend money on a product you want everything to be right.

It's not like getting a 2 headed nickle which will make it increase in price. I would check out some other M-4's and see if they are the same. If so than thats how it is, but if they are smooth and don't have these marks send it back.

Function is the most important thing, but when you pay close to $1000 for something new, it should at least look okay.

I purchased an A3 M4 about 2 months ago and  do not have the finish problems that you describe. The rifle shoots like a dream, 2 clicks off on windage out of the box.

I was back at the same gun shop today and found a few others that had the same tool marks.  Not all the Bushy's had the marks so I asked the owner of the shop to explain.  He said that near the end of a tool's life it gets dull and begins to chatter during the machining process, thus causing the tool marks.  He said that if it bothered me, Bushmaster would replace it free of charge however, the marks shouldn't affect performance or longevity in the weapon.  I'm gonna shoot the shit outta this gun so I probably won't send it back but I'm still of the opinion that if you pay a thousand bucks for a gun, it otta be pretty damn perfect right out of the box.
