Fantastic LPK, comparable to the BCM LPK but cheaper. Trigger is much nicer than standard milspec. I would say it is similar to ALG ACT.

Very nice kit, shipped fast. I liked how most everything was mated up with it's corresponding parts; it shows that care was taken when it was packaged, and not just thrown in a bag and shipped.
