UNIT4 – Realistic AR15-Style Training Rifle for Safe, Flexible Practice
The UNIT4 v1 Series delivers true 1:1 size, weight, and handling in a non‑lethal AR‑style platform designed for safe, flexible training in any environment. Its aircraft‑grade aluminium receivers, free‑float barrel design, and uninterrupted Mil‑Spec 1913 upper rail create a stable, durable foundation for realistic, repeatable reps. M‑LOK attachment points along the handguard and integrated QD sling mounts on both sides support full modularity and fast configuration changes.

The v1 Series pairs a heavy‑duty outer barrel with a smooth‑bore inner barrel for consistent performance and a dependable baseline for customization. Outfitted with a rugged M‑LOK handguard and Magpul furniture, the v1 is ready to configure into a wide range of setups, making it easy to match specific training needs or replicate a preferred rifle configuration

Train indoors or out — the UNIT4 is ideal for skill development, scenario-based training, or introducing new shooters without the risks of live fire.

Purpose-Built for Realistic Training
The UNIT4 is specifically designed for realistic, hands-on firearms training in non-range environments.

Train Where You Live
Use it in your home, garage, garden, or training space. Perfect for dry-fire practice, skill building, or force-on-force drills with your team.

Authentic Feel and Function
The UNIT4 mirrors the weight, dimensions, and controls of a real AR, including recoil. Compatible with standard AR accessories for a true 1:1 training replica.

ATF-Compliant and Non-Lethal
Classified as a non-firearm by the ATF, the UNIT4 cannot chamber live rounds and ships directly to your door — no FFL needed. Use safely with eye protection.

Built to Endure
Upper and lower forged aluminium receivers, US-made steel internals, and tough impact-ready magazines. Backed by a 5-Year Warranty.
