Cryostructure M16A1 Profile 80 % Receivers


Our goal was to make a small batch of 80% M16A1 lowers in order to reduce the overall cost for clones and from $550 to less than $200.

Our lower receiver matches the features of the original M16A1 Receiver. Perfect for a “Retro” or reproduction builds, these lowers are the same design profile of the M16A1.

Matching front takedown lug profile and profile surrounding the receiver extension. Most forged lower receivers produced today feature “A2” profiles, which are incorrect for M16A1 reproduction builds. The lower starts off as a 7075-T6 aluminum CERRO forging, then is machined to mil-spec dimensions. This item is left in the raw to do either grey, cerakote or black anodizing after acid etching your logo on the lower.

Standard AR-15 & M16 components will work perfectly with this lower.

Simple, engraved markings on the lower include:

Completely UNMARKED as an 80% lower, perfect for any reference period clone build.
