First time builder. I have all my parts, with the exception of a LPK. I can't find anything on the forums comparing the kits. RRA, Bushmaster, Stag, DPMS, Olympic, etc.... Who's kit is the best overall quality? Which kits are chinsey? I notice the prices are within $10 of each other, so it's even harder to decide.... I have a Mega Gator lower if it makes a difference. |

Avoid DPMS if possible. I had to spend 15 minutes with my grinder to add the proper notch on the top front of the hammer. I hope it didn't kill the heat treating on the hammer face. A buddy had the same problem a DPMS LPK. The hammer was catching the back of the firing pin and keeping the bolt from closing; not good for firing pin or reliability. I don't care if DPMS supports 3-gun shooting, they are on my avoid list for now. Here's a link to the troubleshooting section of the forum: www.ar15.com/forums/topic.html?b=3&f=66&t=269494 |
I've used a bunch of different LPK, and the only ones I'll use now are the CMT/ STAG. I was playing around with one earlier tonight, and they really are that much nicer than the rest. |
Maybe it your lower that is out of spec. The notch in the hammer is to catch the bolt/carrier group in case it goes full auto on you. |
the notch catches and there have been several cases. carriers with shrouded firing pins remedies this |

i've haven't put together a ton of parts kits yet, but i've good and bad about all of them. the only negative thing i can say is that i've bought a few parts kits from DPMS that had "soft" pieces. safety selector and/or pins that wore excessively in the first few hundred rounds. i seem to hear consistently that bushy combines great quality with affordability. |
| With regards to plastic vs/ aluminum trigger guards... it is my understanding that under extreme circumstances, and aluminum trigger guard can bend, blocking the trigger from being used. Under the same extreme circumstances, the plastic trigger guard would break away, leaving the rifle/carbine still functional. |

My factory rifle is a Bushmaster, and I have to say it does kick AZZ. As a matter of fact, all my parts less the stripped lower are Bushmaster. The lower is Mega Gator. I've decided to go with the RRA LPK and a RRA NM trigger (in the EE, BOTH for $149!). Thanks guys!!!! |
lol). Thanks, again!
I did. Read about 3 posts above this one..... I just hope I don't get "spoiled" on it, lol.

LPK are almost all the same from quality MFGs. As long as they are forged parts, you can't really go wrong with any of them. I stay away from some that have plastic trigger guards or mag release..cough cough I like DPMS but the roll pins are hard to get in on some receivers and I've ruined some finishes. I like CMT but the safety is a bit mushy. I haven't found the perfect LPK but out of the ones out there, I like CMT/STAG the best. |
That sounds like BS to me. All you would have to do is open up the trigger guard if it were blocking anything and that would sove your problem. They are made to pivot open. |

I use RB Presison first time builders kits for most of my lowers. They go together easy and are the cheapest priced kit out there. All their parts are name brand stuff they shopped around and buy in bulk the individle parts and put them togther in to a kit form. I think they use a lot of RRA parts in their kits. RB Presision LPK sale thread |
The RB Presision LPK come both ways when you order one just make sure you ask for it to be sub assmbled. I don't think any one else out there will do that for you. Robert and Krista from RB Presision are he best. I just got two kits to day and i noticed they use Colt hammers in their kits or at least i think they are Colts they have a "C" on them. I went and looked and all my other LPK's from RB Presision and they all have Colt hammers.
