I recently bought a CMMG M4LEP-A .22, with the full intention of buying a 5.56 upper at a later date.
I've began research on on M4 5.56 uppers, but the options and information is so far pretty daunting. Any advise on how to narrow down the choices? I realize this is about as bad as asking a stranger to pick you out a wife... 
I don't want to buy something cheap but I don't want to go over a $1000.00 either. I was really just going to go with a CMMG 14.5 M4, Pin on piston gas block and K7 free float rail, to match my .22LR upper, but having ONLY looked at CMMG I thought I had better hold off and look around. |

What do you want to use the rifle for?

Two of my favorite bangs for the buck. Smoooooooth and reliable.

Home defense, maybe some 3-gun, plinking. The .22 upper is mostly for plinking but you gotta practice with your teeth in now and then.
I probably don't need a top of the line upper, but rather buy more than I need now than have to pay more to swap out parts later for things like grip rails and upgraded ramps. |

If I was looking for just a upper my recommendation would be the same if it was for a complete rifle as well.
Spikes or BCM would be my first choice. I would also use their BCG and the Mod 4 Charging Handle. |

It's hard to beat BCM uppers for the under $1000 price range. I have no personal experience with the Spikes.

The local guys I talk to (enthusiast and ex military) are all telling me that the piston upgrade is worth it's weight in gold.
I can't find a any recent reviews pitting CMMG's piston system against others. How does CMMG rate in the 5.56 Piston Upper game? |

Looking at maybe getting an M4LEPII upper at this point but looking for opinions.

I've got to mention Del-Ton. They've always been great tools for a very competitive price.
14.5" upper http://www.del-ton.com/AR_15_Barrel_Assembly_p/dt1018.htm or my favorite a 16" middy with light weight chrome barrel options. http://www.del-ton.com/Custom_Upper_p/cu104.htm |

? I've had the same turn around time with CMMG when I bought my M4LEP22-A. Though I'm not in a hurry for the 5.56 upper.
I'm just a bit overwhelmed with the choices for brand and type, and want to make a well informed decision. |

Any negatives about CMMG uppers, or gas piston systems?

Nothing beats pinned for reliablitiy. Clamp on anything will always have the possibility to move. Doesn't mean it will but the piston is moving back and forth in the block. It's not like a clamp on FSB ot gas block.

I had tried searching in the past but since I wasn't a member when i started this thread, I wasn't able to come up with anything useful.
I should have gone back and started searching but this thread was already rolling. (and honestly, I forgot  )
I've gone back and began reading some of the threads I found, I haven't found a lot of recent first hand dislike of CMMG though. A lot of 2nd and 3rd hand experiences, and some posts about old rifles. Not a lot of well explained Piston vs. DI discussion either, which is the reason a lot of us here began looking at CMMG, that and their excellent .22LR products. Living in MO I'd like to give my money to a MO business if possible, but I won't do so for an inferior product or for a future of bad customer service. The other suggestions I keep seeing are Spikes or BCM... I don't know anything about them. I'll have to do a little more research. |

I, along with several others, have had bad experiences with CMMG. Conversly, many others have reported good experience with them. The kicker is that if you need service from CMMG you may not get what you paid for. They are notorious for bad CS, unlike the BCM & Spike's. If you have a problem with a BCM or Spike's product you can bet your pay check that they will take care of it. CMMG on the other hand may or may not fix your problem & historically you might be more likely to experience troubles with their products. I used to like CMMG about four years ago until they screwed me. My tune soon changed within that year. Good luck with which ever brand you choose to go with.
