I have LPKs from Model 1 Sales and DPMS. I can't decide which one to use in my build. I have one of those Tactical Innovations deluxe billet lowers. Thanks for any advice.

I've got 10 of each LPK over here, want to come check them out yourself? Well I did, and that's why i made the statement that Model 1 sales are better than DPMS. I think that the vendors are all scrambling to meet the increased sales demand so that some batches are better than others. As they ramped up to meet the highly increased volume the quality control goes down.... And that's what we are seeing. As to the OP question of which is the best LPK to go with - I would go with RRA - I have not seen any deterioration in their quality control of any of the parts in their LPKs. YMMV Quoted: Quoted: Model 1 sales LPK's are superior to DPMS. LOL! 2 out of 2 Model 1 sales LPKs me and my friend bought were out of spec. holes on the disconector were not in the right spot. DPMS lpk is way better than Model 1. |

I only use RRA or Stag LPK's in my builds.
IMHO, DPMS kits are just not very good quality, I don't even think they use the same parts in the guns they build themselves. Every DPMS parts kit I got was a odd color and I've had out of spec parts that did'nt work. Their factory rifles have black parts and they work.

| I installed an LPK from Model 1 Sales in an Essential Arms lower a couple of months ago. Everything fit perfectly. Don't know what if anything it means, but the hammer of my LPK has a couple of Ss stamped into it exactly like I saw pictured in another thread on this site. Those pictures were said to be from an RRA kit. Same manufacturer? |
I'm betting that a few machine shops that contract for the military and most of the manufacturers are stamping them out as fast as they can go and supplying everybody. Who thinks Model one, Stag, RRA, CMMG, DPMS and everyone else is set up to stamp out all their own small parts? Just put it together!

They're all the same to me; I don't think there's any trash LPK's floating around like there used to be in the 80's and 90's anymore. YMMV
JMO, but more importantly than the name brand, I DO like roll-pins better than solid pins. They seem to be easier to work with and more forgiving in out of spec lowers. Solid pins have to fit perfectly; that can make assembly harder, put more stress on the thinner parts, or if the receiver holes are over-bored, the pins will eventually walk/fall out. Not common, but I've had it happen a couple times.
