would it matter if i get brand x lower receiver internal parts compared to brand y lower receiver internal parts? any recommendations would be appreciated? what do you guys use?

Yes some LPKs are better than others. I've had good luck with DD and Stag. ArmaLite was all right. I didn't like DPMS or Del-Ton, both were rough.

The internal parts that go inside the lower receiver are one of the most important factors in determining whether you have a good AR or just a so-so AR. In fact, when it comes to AR lowers it's about the only thing that matters. Your choice of buttstock matters I guess, but not so much.

I had good luck with a Rock River LPK that I bought through Joe Bob Outfittters. The trigger parts that make contact with each other were all highly polished and that resulted in a crisp, smooth as silk trigger pull. Everything else in the LPK seemed 1st rate and went together without any issues.

I ordered 2 LPKS from Palmetto and one of them was smooth as glass the other I was not happy with . it took alot of time cleaning it up and polishing it smooth but its up to par with the other kit now. I would have to say stay with a good known manufacturer like stated above , and if you do get one thats not great they will take care of you .
