I am thinking about building my first AR, but I wanted to know what lower parts kits are good to build on.
I see DPMS, RRA, Bush, DEL-TON, Daniel Defense, STAG ect etc... I see that DPMS is the least expensive. Are the lower parts kits essentially all the same in quality with companies charging more for the brand? I'm not looking to build any super high performance triggers, or going into battle, or competing, so I'm not looking for anything fancy like that. I just want to kill some paper...for now. Thanks |

Thanks While you'll get different answers from others, the answer to your question is YES, they are all pretty much the same unless they come with a different grip, match trigger, anti-rotation pins, different material parts, etc. I have had no issues with DPMS LPKs in the past. |

Yeah, I figured that people would get real specific in the preference for the lower kits but, I think you answered my question. I am more interested in the internal parts. I can always swap out the grip and trigger guard for ones I like. and like I mentioned I'm not looking for a specialty trigger job or to go full auto. Just something that will install into my lower, and not break after 50 rounds. Can you explain what anti rotation pins are and how they function? |
| I looked for weeks at LPK's and came to the conclusion that they are all the same. Some companies use the coiled type roll pins as was mentioned above, but I haven't heard of either type breaking with enough regularity to say one was better than another. Some use specific trigger components but that is going beyond a standard LPK. The only one I found that uses a specific part is Armalite and their bolt catch. I liked it so much I bought that 1 piece and added it to a Spikes LPK. Unless you get a specific trigger...you wont notice the difference in any LPK other than the price. Non-rotational pins use a retainer on the outside to lock the pins as to prevent them from rotating in the holes. The thinking is a steel pin turning in an aluminum reciever will eventually wear the hole to a larger diameter. They are a waste of money but companies sell tons of them. If I paid thousands on a registered receiver I might buy them as insurance. Good luck, the LPK question comes up every week, you'll see it again soon. |

Thanks, I tried to search the forum first but I wasn't finding it, so I just posted it. But thanks for not being a Richard for asking a simple question. I see a lot of replies that rip into to people's honest questions, I think they sometimes forget that at one time in their life, they once a regular dude that wanted to build their first AR.

As was noted, essentially all basic LPKs are the same. But the spiral roll pins can be easier to install. I like the PSA LPKs... They give you options for various triggers, trigger guards, and pistol grips. Saves some money in the long run. How much more work are the regular roll pins as compared the the spiral roll pins? The only pin I have knocked out and back in was for the replacing my trigger guard for the Magpul guard and it it wasn't that bad. |
| If you are looking to build just a shooter...Probably any kit will do. If you follow the tried and trued procedures for knacking in the roll pins, you should not have any issues. The coils are cool sounding, but I have zero exerience with them. $50 lower kit is a good price. |

in general terms, they are all pretty much the same. whenever i use one that does not have coil roll pins I toss the roll pins and use coiled ones. they are much easier to install. Are the coiled roll pins available for purchase separately? Now curiosity has been piqued. |

Yes, go to RRA website and buy the individual roll pins. http://www.rockriverarms.com/index.cfm?fuseaction=category.display&category_id=287 Spend $25 get free shipping. |

More in the design than in the installation. |
| Don't get all wound up about the type of roll pins. The ones in the DPMS kit that you're looking at will be fine. I wouldn't worry about it, Maybe later on, if you deciede to assemble another, you can look more into them. For now, buy the DPMS kit and spend extra coin on ammo and magazines. Those are way more importent than a different style of a pin. This place can be intimidating, make sure you don't get bullied into buying uber expensive parts before learning the basics. |
