Stellar × The Mad Chemist — Limited Edition 12.3” AR-15 Pistol Stellar FDE

Forged from flight and chemistry, the Stellar × The Mad Chemist 12.3” 5.56 pistol merges Stellar’s aerospace machining with Mad Chemist’s signature surface style. Each unit features a CNC-machined 7075-T6 receiver set, Mad Chemist dimple-textured handguard with custom grip section, and a custom Stellar V6-QD brake finished in gold heat treat.


Internals are duty-grade: an M16-pattern nitride BCG, ELF Tactical SE trigger, and Stellar AMBI-MIL charging handle engraved with the Mad Chemist logo. Compact, balanced, and serialized for authenticity, the 12.3” pistol brings both mechanical precision and artistic identity to the range.


Available in Stellar OD Green, Stellar FDE, and Stellar Black, each pistol ships with a Savior Specialist Covert sling, two Amend-2 30-round magazines, and a Certificate of Authenticity. Limited run only.
