    Nitride LPK

    Posted by LZ on Sep 24th 2020

    This is a high quality LPK. This was my third one, I will only use White Label Armory parts for all my builds. I have never had a bad experience with any of their parts. Everything, including this LPK is machined perfectly and always works, that's what matters.

    What Craftsmanship!!

    I am pretty new to White Label Armory, wasn't sure what to expect. I put this LPK in a lower as soon as it came in. I have had issues with other LPK's, not this one machined to perfection. I cant wait until their lowers are back in stock so I can build my next AR in a White Label Receiver. How will it do with a 6.5 Grendel Build!?!?
