UNIT4 – Realistic AR15-Style Training Rifle for Safe, Flexible Practice
The UNIT4 delivers unmatched realism in a non-lethal AR15-style platform built for safe training anywhere. Designed with the same dimensions, weight, and feel as a live rifle, it features aircraft-grade aluminum receivers, a smooth bore inner barrel, and a free-floating outer barrel system for realistic handling and performance. M-LOK mounting points, full-length 1913 rail, and QD sling attachments offer full modularity.

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.
