Bought a DPMS. Has a piece of metal in the barrel from cutting the twist. Called DPMS. Their lower distinguished by a letter K at the end of SN said it was shipped empty to 2nd party. Barrel is not theirs either. Found out it is a put together gun. WHo makes this barrel with marking on top of barrel 5.56 NATO 1-9? Nothing else on barrel.


Thanks in advance

This is fairly common. Usually it's a burr caused by machining the gas port and it will shoot right out on the first round.

Can you post a pic so we can see what your are concerned about?

BTW, there isn't anything wrong with a custom assembled rifle as long as it was done right and good parts were used.

The burr is in the middle of the barrel. It looked like a spiraled piece of metal like you would get from drilling in a drill press, about an 1/8" to 3/16" long and looked about 3 times longer than wide. Hooked on a cleaning rag the first time. Pushed a brass bristle down the barrel, caught on it and half way folded it into the rifling groove, but not all the way . You can still see it quite easily but the point is it is attached pretty good. It catches the brass bristles no pretty good either pushing or pulling. Im afraid if I shoot it it will burr a groove all the way down the barrel or fold completely into the rifling groove only to come out some time in the future and then still scar the barrel. If I knew the mfg I could send it in to get removed.

Use your cleaning rod and brush to try and determine the location of the burr. Is it at the gas port? If yes this is very common and it will shoot out on your first round.

if you shoot it, it will be removed

The markings you posted can not be used to identify the barrel. As others have stated its fairly common, just shoot it.

Here are his pics. Only markings we saw were the Caliber/twist stamp.

Remove the hand guard to find the makers mark. I had an early Black Hole barrel that had markings near the barrel nut; the mark would never have been seen without removing the guard.

There's a whole bunch of makers that don't label their barrels, nor do many of the final machinists that would've actually profiled the blank and drilled the port.

True but lets not discourage this person from at least looking. If the answer is not found they could probably have learned something about hand guard removal.
