A buddy here at work is selling me his unfired DPMS 20" fluted, stainless upper for what he paid. Can I get some opinions on proper breakin for it?

From their website:

"We recommend cleaning the bore every round for 25 rounds and every tenth round for an additional 100 rounds. Use a bore brush or bore snake with either CLP or solvent."

also a link to a digital version of their owners manual:

Here


What I did was shoot 1 round then clean barrel with CLP and a boresnake for 25 rounds, Then do a full clean.  Then I believe I shot 1 full thirty round magazine followed by a full clean up to 100 rounds.  Then rock and roll.  I think there is debate about whether this is necessary but it won't hurt your gun and is a good way to slow down and sight your gun in at the same time.

Thanks, I figured I'd do something like that. I would have done a search, but I figured I'd get to know some minnie guys this way.

Use Militec-1 or Slip200 EWL.  Not just any CLP or solvent.  Those will bond with the metal in the barrel and make your bore fouling less of an issue during operation.

ETA:  It's less of an issue in the chrome bore guns.  I would do it in a Stainless Barrel, though.

 Yup.  Militec-1 works great in stainless guns!

I'll hit the gunstop for lunch tomorrow, if he doesn't have miltec, I'm sure John will have an opinion on what I should use.

Shoot it like you stole it.

I was in GS two days ago.  They still had 1-2 bottles of Militec.  So no worries.

I have a few extra on hand if anyone needs some.  1 bottle is basically a lifetime supply.

Just made the transaction, and it is sweet! I really wanted a 16" but  I've been on waiting/backorder lists in FAL land, and I'm not very good at it.
