We now have the only 80% lower in the country that clones the M16A1 profile. Made out of 7075-T6 aluminum and because of the contouring they are taking a total of 3 hours to machine out for each one.
We can do deep laser engraving for an additional $50 per lower.
This lower is the proper receiver for the following reproduction builds:
