Any particular reason why you want a piston upper?

Sheepdog.....I am a newbe in the AR15 world. I have been stressed by a friend that loves his in that it is much cleaner system. Your thoughts please...

I have owned Piston Weapons before and I own a Mil-Spec M4 and a SPR in 6.5 Grendel and a dirty chamber does not cause issues atleast for several thousand rounds.
Many, many, many shooters use DI systems for heavy carbine courses and 99% of them don't have issues with the DI system, rather magazines are the greatest threat to an auto-loader.
The thing I dislike about the AR-15 Piston system is how you clean it. Yeah you're keeping minor dirt/grime out of your chamber, but in order to clean that mess from underneath your handguard, you have to remove the handguard-can be a pain in the butt too.
Some pistons also pose accuracy loss and this has been confirmed by many people.
So my question to you; is the gain of a slightly cleaner chamber worth it? You'll add extra moving parts to your system and the only versatility you'll gain is reliable suppressor use.
More moving parts = more parts to break.
DI systems are tried and true and I have yet to see a failure in my uncleaned Daniel Defense M4 with 500+ rounds down the new barrel.
A quality DI system (BCM, DD, Noveske, Colt) will impress you more than a itty bitty op rod above your barrel.

Most of the initial claimed benefits of a piston system over a traditional AR have been debunked or atleast minimized by actual real world application. The one place that a piston system seems to be a plus is when it is used in conjunction with suppressed full auto. In a civilian semi-auto it doesn't really make a difference. That said, if you like the idea of a piston upper and you have the extra dough then go for it. It's not like the piston system sucks or anything.

I was going to comment on the piston, but since I don't own either....
All I know is 20 years of running Uncle Sam's DI M16s.
I just can't figure out why more moving parts could make it "better".

You can get a PROBLEM FREE direct gas upper from BCM for much cheaper. A clean running piece of junk is of no value to me.... just my thoughts on the subject.

Sheepdog, you have made some very good Points...Now looking at a Daniel Defense Upper. I have heard a lot of good reports on the Daniel Defense product. I appreciate your and others remarks. Thanks for pointing me in the right direction.

They are very well made. BCM would probably be my top choice just because they have more barrel options, but a Daniel Defense is top of the line. Mine is awesome! I put a Lothar Walther SS barrel on mine and I consistently get 1 MOA with surplus ammo.
