Question for the Pros. Recently bought a  mk12mod2 upper with all milspec parts. Unfortunately the upper was painted in camo  and that's just not my thing. So I took it to my local gun store and had them cerakote it black. After a few weeks it was ready and I picked it up. took it home and installed lower. put it in safe using barrel storage sticks and the bore is extremely rough. it feel like fine sandpaper in barrel. I dont know if this is the way I bought it or the bore was painted with over spray  by gun store. The question is should I shoot it? Any suggestions?
Thanks in advance!

Does it look like overspray? Is it just near the muzzle. I would determine if it is cerakote best I could. If so then take the issue up with the business who cerakoted it. If not your kind screwed. Hard to say if shoot it. If it's not really much of a build up I'd probably put a few rounds through it myself, but that's just me.

feels like its in most of the barrel. and i cant tell what it is. So I hate to take to gunstore . I was told it was built by High caliber sales  for$1600, I paid $1100 +100 for paint job + Lower

Run a bore brush through it and see if that clears it. If it does not, bring it back to said LGS that did the paint and show them. They were the last to work on it, they should have checked it out before and after work was done and documented it in writing.

Butchs bore shine, run brushes thru until you think you got it all, soak a patch in lighter fluid and run it down the barrel. Then clean and oil like usual.

If butches bore shine doesn't remove it, take it back in.

Kroil and bore paste might work, too.  Normally...only the power of Christ or a sandblaster can get through a layer of CK....BUT if it's just paint powder you might be able to do it.

Ran the brush and it worked a little but Its still rough. Ill try using the solvents and see if they help. thanks for all your advice. If not Ill try the lgs that did the paint job.

I don't know of any solvent that will take Cerakote off. It will have to be scrubbed/scrapped off.

 

Use the solvent as a lube and run a bore brush up and down repeatedly and then run a couple dry patches down it. Do that a couple times and see how it works out.







If it were me, I'd probably load up about 20 rounds and see if the bullets will finish the job. I would also set up a target at 50 yards to see how the bullets are acting.


You could do it at 100 yards, but I doubt your scope is zero'd, so it would be harder to make an accurate group at 100, but it's worth a try.




But I would definitely notify whoever did it. Cerakote has become so mainstream, that a lot of people are doing it now days. You just have to be careful on who you choose to do it (i.e. a certified cerakote finisher). I went to a gun show a couple months ago and there was a booth there displaying their cerkoted guns. Their "tactical" colors were shiny as shit. I listened to how they do it, and they tuned down a guy wanting a Glock slide done (good for the Glock owner). The guys at that particular business only buy the 4oz tester bottles and use the entire part B syringe in the 4oz bottle to finish one firearm (i.e. they don't measure the amount of part A to part B) . They just mix it all together and then throw away what's not used at the customer's expense.
