I am currently in the process of building an AR-14 from the ground up. I am sorta new to AR-15's so I am in need of some opinions. I currently have an Anderson stripped lower that I am looking to put a LPK in. I think i have narrowed it down to two brands, but i cant decide and was wondering if i could get some help. I found a bushmaster complete LPK on sale for what seems like a decent price (50) and I have also found a few spikes tactical LPK's for around 65. What do you guys think i should go with? I want quality parts that are going to last and function great. Also I am trying to achieve a mil-spec rifle.
