LMT semi auto carrier/key only. Approx. 300 rounds on this, it looks new. I am the original owner, purchased from Quantico Tactical. THIS DOES NOT INCLUDE the bolt, cam pin, FP, or retaining pin.
The LMT carrier has chrome lined internals and has heavier profile at the rear of the carrier group and under the firing pin.
IM WORKS BEST, thank you.
