Lower stripped quality. Most will say it doesn't matter. Some will say yes. I say that it doesn't matter one bit as long as it isn't polymer.
Meh that's another iffy thing. Some swear by Spikes enhanced LPK and other say that it's useless. However, I am going to say that as long as you get a quality trigger kit you may skimp on the rest of the LPK.
I am not an AR expert. I just have a understanding of the market and how they go boom. Carson will be able to give better advice.
