Looks a lot like the first gen POF upper I had and really liked.

They take down just like the POF early system correct? 1 detent pin in the gas plug? The screw in plug is
for the conversion kit version only?

Anyone here have expereince with one? How has it held up when ran hard?

?????

Knight, we are not ignoring you.  There is lots of info on this forum about the function of the CMMG system.  I will politely suggest that you explore the shitty search function on this forum.  I have not shot or used a CMMG, but they are producing many of these, I'm certain that if they were shit we'd hear about it.  You know how it goes, it works nobody says anything, it doesn't and they scream from the rooftops about it.  



I hope this helps.

I can't really speak to the others but I love mine. I had an issue with the free float hand guard (cmmg factory installed) not staying tight but some loctight and a bing wrench now that's fixed! I have had a hammer pin break and the charging handle latch pin break I put the lower together and installed a gun fighter latch so those are on me I'm sure. I think for the money you get a great product.
There customer service is great they have a very knowledgeable staff. I have many friends and family that have bought from them on my recommendation. If you have any questions or need pics of something I will try to help as much as I can.

I can't answer your questions regarding the similarities between CMMG and POF, but I can tell you that I really love my CMMG piston carbine.  It has never failed me and take-down is a snap.  It seems the engineering that went into this system was direct and simple, but it works.  It's my "go to gun" if ever the need presents itself.  That's saying a lot because I have upper shelf AKs, an H&K and other DI ARs in my arsenal.  I'll post a pic for you as soon as I find my friggin camera!

I had no problems at all with my CMMG gas upper and RRA lower..  Was perfect all the time.

I'm going to go with a SureFire 951 and LaRue offset mount, but that's about the last of the changes.

Thank you for posting these pics sir. Very fine set up! Would you be willing to take and post a few pics of the bolt, carrier, and gas
system as well? Thanks much

Sure.  No problem.  I'll do it this evening when I get off work.

Bud

Thank you Bud!

As you can see, I suck at photography.  Parts are clockwise:

Piston, Gas Plug, Piston Return Spring, Carrier, Bolt, Firing Pin Retaining Pin, Firing Pin and Cam
