Cryostructure Posted March 24, 2024 Report Share Posted March 24, 2024 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: M16A1 Model 619 Model 629 Model 630 / GAU-5A Model 639 Model 649 / GAU-5A/A Model 651/652 Model 653/654 Mk 18 Mod 0 Mk 12 https://www.cryostructure.com/product/m16a1-80-percent/ Link to comment Share on other sites More sharing options...
