Piston will gain you a cleaner Bolt Carrier Group. You'll appreciate it when it comes to cleaning and maintenance time, your trigger group will also remain much cleaner. MY opinion here but there's something to be gained by a piston setup keeping the carbon from being redirected back to your Bolt Carrier Group. Also - you can now add bit of grease to your Bolt Carrier Group that I would not advise when using direct impingement uppers.

Comparing my Colt LE6920/Colt 6601 side by side with my gas piston guns the gas piston guns are so much cleaner at cleanup time.

Why would you not advise using grease in a DI AR?

People clean their firearms? Maybe I should start.

That whole easier to clean thing has merit but the carbon still collects in your firearm, it's just in a different location.

I'm curious too about that comment. I use moly-lithium on the wear points of my bolt and carrier with zero effect on the utility of my firearm.

I asked the question knowing he wouldn't have a credible answer . We'll never get anything of substance if we get anything at all.

I've been known to use transmission fluid. I use brake cleaner afterwards to clean it. I am really lazy. But my guns still fire every time.

On a DI you get a lot of residue all over the bolt and carrier, the grease gives the residue an attachment point turning the grease into an abrasive rubbing compound . The piston only gets a little residue from the primers therefore the grease stays a lot cleaner. I still use a little grease anyway whichever system I'm using.

If you really want a slick system go with NP3 Plus and a piston. No cleaning, no lubing. An infantry mans dream.

Riiiiight.

Funny how all the piston automatic weapons (M60, Mk43, 249's and 240's) I ever used in the service (28 years) were just as filthy as the DI M16's I carried.

I use grease out of a tube. I apply it to my DIs, AK, Rem 1100, 870, and piston AR w/ a q-tip in generous amounts. It's like $5 at WalMart. The action is smooth, very smooth.

People are really buying into POF's bait hook line and sinker.
