[ARCHIVED THREAD] - DPMS vs CMMG LPK (Page 1 of 2)

Trying for a budget build.
Which parts kit is preferred? DPMS or CMMG |
|
I have never used the CMMG LPK's, but I have used 4 or 5 DPMS LPK's and have never had a problem of any kind with them. And, I got them for $29 and change from Brownell's (minus FCG): http://www.brownells.com/rifle-parts/receiver-parts/parts-kits/lower-parts-kits/ar-15-lower-parts-kit-less-trigger-group-prod73622.aspx There are more than a few on here that will curse the ground the DPMS factory sits on. Maybe I've been lucky...I can't say, but it's been all good with any product I've gotten from DPMS (including one of their bargain rifles). YMMV. |

They are both junk.
The CMMG had the worst trigger I've ever felt in a LPK. The DPMS had soft parts. Bolt catch peened. Selector wore. If you're on a budget, the PSA kits are ok. The finish wears pretty quick, and they may forget a spring or detent. But the triggers are pretty decent and selectors click positively. |

lpk is generally a lpk This couldn't be further from the truth. Would appreciate a little clarification on this. I have examined a lot of lowers and can find very little differences in them. Certainly not enough to say to avoid any certain brand from a major manufacturer. |

Just because the part look the same, doesn't mean they are the same. |

The parts is parts arguement is not only weak, but it's bullshit. It really does no good for a new member who is looking for solid, accurate information. I agree with this. But as far as my CMMG and DPMS LPK's I can't legitimately say one is better than the other. All of the above haven't given me any issues. Although, the trigger pull on my CMMG's have had a horrendous sandpaper false 2 stage feeling break. But other than that, they've both been great for me. |

You never have anything to back up your troll arguments either. People in glass houses, and all that... I stick with Stag, DD, Armalite and most recently, Colt I can only speak from my experience, and why I choose these 4 PSA is not on the list, and probably the most widely used on this board. Never again for me. The 3 I bought had a mixture of pieces out of spec, anodizing not uniform, and soft detents. DPMS is another that had butter detents in 2 rifles owned by friends. This is a small sample size, but is more than enough for me to make a conscious decision and avoid most brands but the 4 I mentioned. I have used the Stag and DD the most, but Armalite is gaining my favor. I have used the spring kits on several that friends and colleagues have had issues with bent, or short springs from cheap ass kits |

I've done several builds with each. The triggers are a little scratchy out of the package, but either one will build a serviceable lower. I lube the hammer/sear engagement surfaces with Remington 40-X bore cleaner, which has a polishing compound in a light oil that works well to smooth out the engagement surfaces. After 50-100 rounds, clean thoroughly, and you'll have a very smooth trigger.
I've not had any problems with either, and have done more than 4 builds with each. |

There is a new post on here about a guy having trouble with a Geissele trigger. Imagine that! And? Does Giessele consistently put out sub par product? Or do they have a well earned reputation for quality and customer service? Try trolling somewhere else, and take the other 14er with you. |

You're are intentionally being obtuse. You bring nothing to the discussion in these technical forums. |
One of these things is not like the other...
The black lower is an early BCM factory built lower. The FDE lower is an Aero Precision circa 2009 with a DPMS LPK. After noticing the peening on the bolt catch on the DPMS kit, I pulled the trigger group and replaced it with one from PSA. The selector in the BCM lower is positive, and clicks audibly when engaged/disengaged. The DPMS kit's selector does not click because the detent is rouned off. How many of the springs, detents and pins were tested and certified by DPMS to ensure it's quality? I know how many were in the BCM lower. Now tell me... How are they different? |

I didn't say they didn't. Can you read? My point is any mass produced machine is going to have failures. I am so sorry but I have been shooting DPMS products for a long time without a single failure of any kind. My deepest condolences to you and the other brand bashing trolls. Your definition of trolling obviously means disagreeing with a genius like your self. How could I dare??? Leave? No, I am going to stay here and listen to you elitists feed BS to the newbies. Very entertaining. You have answered my question quite well thank you. When I grow up I want to be just like you. |

Where is you technical contribution to this thread? All I'm seeing is your emotional attachments to a product. |
| Several years ago, a poster here on ar15.com claimed to be a former employee of CMMG and further claimed that CMMG lpk were just DPMS parts. If I remember correctly, CMMG basically confirmed that the guy was a former employee and was pissed that he was telling secrets. |

I could be wrong, but I seem to remember that CMMG kit had roll pins. |
