Looks good for the money. Did have some concerns with the bolt catch since it looks MIM. Should be fine for 5.56. For a PCC or heavier calibers Id spend a bit more for non MIM LPK. Mainly purchased it for pins, detents, and springs. Doesnt hurt to have spares.

The only LPK I buy for every build (and to have on hand as spares). Everything fits and functions as it should. Why pay $50-70 for a name brand lpk, when it’s all the same stuff. Leaves you more money for ammo and fire control group.

good price, not a fan of the basket weave pattern on the mag button release.

Worked great and went in place well. Good finish on all pieces. 👍🙋♂️

Great LPK at a great price. I always buy several at a time for future build and to keep spares on hand.

Excellent LPK, especially for those of us who were going to just buy a better trigger and a better grip anyway.
