Transferable RDIAS M16 with Colt MK18 and SUREFIRE SOCOM RC host full auto machinegun

Investment Opportunity: Transferable Stemple Registered Auto Sear (RDIAS)

The Ultimate M16-Platform Package | Colt/Daniel Defense MK18 Host | 3-Stamp Professional Setup

For the discerning collector or tactical enthusiast, this is the pinnacle of the AR-15/M16 world. While transferable lower receivers restrict you to 40-year-old technology, this Stemple Registered Drop-In Auto Sear (RDIAS) grants you total freedom. This steel-body sear can be legally moved into any modern, CNC-machined AR-15 lower, allowing you to run the most advanced platforms on full-auto.

This is a consignment sale currently held in my personal inventory in Indiana on Form 4s.

Transfer & Financing Terms

We aim to make the acquisition of high-value NFA assets as seamless as possible.

Why an RDIAS?

Standard transferable lowers (like Colt M16A1s) are prone to wear, cracked pin holes, and out-of-spec dimensions. With this Stemple Steel RDIAS, your investment is protected inside a modern, replaceable lower. Registered sears rarely hit the open market—don’t miss the chance to own the most versatile MG in the AR-15 category.
