Cerro 80% Lower & Upper Receiver Set w/ Cerakote and Engraving Option
We're now offering a Cerakoted service on our 80% lower and upper receiver sets. Choose from our list of multiple Cerakote colors and have your upper and 80% lower receiver set professionally Cerakoted before or after being deep or surface laser engraved!
SURFACE ENGRAVING SAMPLES:
The upper rear lug will not fit into the rear pocket of the lower until the lower is completely machined and finished by the end user. All of the jigs that we offer will accomplish this.

- Mil-Std 1913 Rail for mounting optics and accessories
- Machined for use with barrels that use an M4 barrel extension
- Deep engraved T-Marks
Lower Receiver Specs:
- 80% Machined (Just needs trigger and safety well machined)
- 7075 Aluminum
- T6 Heat Treated

- Optional safety markings on both sides
