CMMG makes excellent LPK's. RRA is excellent too. I think they have their forever sale on them at like $47.95 or something like that. I've used a lot of them.

PSA lowers with BCM LPK's is all I use anymore.
I can usually find the BCM enhanced LPKs for less than $90 if I search hard enough. |

Thanks all. Since I already have the CMMG I'll just use them, based on the feedback in this thread.
Thanks again! |

If you just want builder kits so you can add the trigger and grip of your choice Sionics and Sons of Liberty are great quality. They are under $40 and i always swap out the grip for magpul k2 and trigger for Larue MBT most of the time anyway.
All high quality springs, detents, and no MIM parts in these |

I have been buying the CMMG gun builder sets for $30.00 on sale. Hard to beat that. Then get Rise 140 SST trigger and Magpul Miad grip and your all set. Good shooting.

Strike Industries Enhanced Lower Parts Kit minus grip and trigger is my go-to Lower Parts Kit now-a-days. Lots of higher quality smaller parts in there such as safety, bolt release, and detents.
$50 from the manufacturer, a couple of bucks cheaper if you look around and can find it in stock. |

I usually end up with PSA kits that include the Enhanced/Polished trigger.
When you can catch them on sale with free shipping, the (PSA) SBA3 brace with EPT kits are the way to go. https://palmettostatearmory.com/catalog/product/view/id/33785/s/psa-moe-ept-sba3-pistol-lower-build-kit-black/ |

I've got a couple of CMMG lower parts kits, and two stripped Spikes lowers. Thinking I want to put a top of the line LPK in them like the PSA I have with a BCM LPK. Is there a better lpk than CMMG that costs less than the BCM? Or are the CMMG kits I have good enough? |

Ive been using CMMG Gun Builders kits and needed an FCG with the last basic rifle build. I bought a full Anderson LPK with the stainless FCG and was surprised how nice the trigger broke and no gritty feel of most milspec triggers. Used a purple spring from an ACT and it performed very well.

Trivial, but I'm curious: what material is "mil-spec" for the mag button, aluminum or steel?
Colt uses aluminum while other highly regarded companies use and suggest steel is the mil specification. |

I think the next one I do I will try a little HOBO oil on the pins, pin bores and the sliding surfaces of the trigger, hammer, disconnector, and springs. I've used their gen1 and gen2 stainless kits. Both have had very nice triggers out of the box. I've also used RRA, Aero, DPMS, Midwest Industries, PSA, Apoc Armory, Anderson Stainless Gen 1 and Gen 2. RRA had the best roll pins (all coil type). DPMS and Midwest had the heaviest feeling triggers of the group. All parts were solid. PSA had a decent trigger but I wasn't a fan of their safety of other small parts. They are functional but had more asymetrical casting that made them look cheap. Aero was solid middle of the road. Average trigger with a little creep but not a heavy pull. All the parts seemed quality made. Similar feel to the RRA. Apoc was OK. Came in an unbranded bag but with an enhanced trigger guard. Trigger and hammer springs were a little weak. Replaced them with Anderson springs from an Oops kit. Anderson Stainless Gen 1 had clean, light trigger with crisp break. Reset took a couple repeated cycles to break in, but is now crisp and positive. Anderson Stainless Gen 2 very crisp trigger. Feels like a drop in at times. No break in needed. So far my favorite out of the box trigger behind my Elftman SE drop in. I expect that there are more MIM parts in the Anderson kits, but so far I have had no problems with reliability or durability. (I also noticed S&W parts kits have been using quite a bit of MIM, too). |

If you check out solgw they lost all the specs and their "blaster kits" are able Milspec parts Yesterday I was comparing 2015/2016 PSA, Sionics and Colt lower parts kits. There is zero difference between them aside from the steel mag button of the Sionics and the location of the markings on the Colt selector (also, no tick). If I were to mix them all in a bag, no one could tell a difference. I was just curious about the mag button as SOLGW claims milspec is steel; SOLGW, BCM, KAC and Sionics use steel mag buttons while FN, LMT, and Colt use aluminum. It makes no difference in the end. To answer OP, if buying today, I'd buy Sionics. They meet the standard of quality I look for in a lower parts kit. Colt also, but they are never in stock. And lastly, my older PSA kits also meet that standard, but due to their volume, I would be hesitant due to differing sources to meet their demand. |

You cannot be sure which you will receive when ordering. PSA has stated that both are sourced from OEM suppliers, but the components are not apples/apples in my experience. I've gotten out of spec selectors and discos, detents with burrs, and fubar springs in kits from PSA. The good is, PSA will stand behind anything that there is an issue with. |

Right to bear kits with the nickel teflon coated trigger group. Great price, and the coated single stage is a significant improvement over standard mil spec.

Quote HistoryQuoted: When Anderson switched packaging on their lower parts kits is that when they went from gen 1 to gen 11? For sure the next one I'm going to try some Hobo oil which I have sitting here on the lower parts. It was mainly developed for bolt action bolts but it seems to be getting used on everything. This guy doesn't sell it but recommends it. http://bartsbullets.weebly.com/hobo-oil.html |

No idea what Gen it was, but the 1 and only Anderson lpk that I bought was the worst quality to date. Shitty trigger, OOS bolt catch (had to file to fit) and springs looked as if they were scavenged from used ink pens.

you can get aero lpk sans the fcg for less than 25 when rtb or b kings has them on sale. Actually, I recently bought several from B Kings at 19.99
I honestly don't think you can beat their lpk, dare I say I like them as much as Colt

Quote HistoryQuoted: I think Gen 2 came out a little over a year ago. Anderson is kind of all over the place when it comes to packaging. They seem to do at least three different types of packaging on a lot of their stuff: Bulk packaging in plastic bags, basic packaging in cardboard boxes, and retail packaging in full-graphics blister packs. My gen 2 came in a retail package. My Gen 1 came in a basic cardboard box. I've seen Gen 1 kits in retail packaging, too. |
