This is my first model—still a work in progress, but already at a fairly advanced stage of completion. I started with the standard AR‑15 fire control group and modified it to create what I consider the perfect battle rifle (similar in concept to the M7). My goal is to turn this into a gas‑operated, shell‑ejecting toy gun. Some of the accessory models shown (such as the LPVO scope and the Picatinny‑to‑buffer‑tube adapter) are open‑source assets I sourced online.

I’ve incorporated a number of features: ambidextrous last‑round bolt hold‑open, ambidextrous magazine release, and an ADAC‑style system (similar to the one built into the Radian Model 1) that automatically locks the bolt back when you press the magazine release button. It uses a side‑charging handle, an M‑LOK handguard, and is designed with a direct impingement gas system.
