LPK - Lower Parts Kit AR15 223/5.56 (no Grip no Trigger, No Hammer)
It's honestly the best price for an LPK anywhere on the net. Biggest plus is the Ambi Safety Selector. I also like the 3-notch trigger pins. The oversized trigger guard is a step up from the standard flat trigger guard. What the kit did NOT come with is the Grip Screw & Washer as pictured. Still, I would definitely buy it again.
