UNIT4 Training Rifles
Made from the same materials and processes as your live AR. Compatible with your existing AR furniture.
Train anywhere. Every rep transfers.
The UNIT4 is a purpose-built AR trainer with the same fit, form, function, and recoil as your live AR — but classified by the ATF as a non-firearm. The reps you put in at home carry straight to live fire, for a fraction of the cost and none of the range fees.
1:1 with your real AR
Matched dimensions, mil-spec ambidextrous controls (safe/semi/full), and CO2-driven recoil, compatible with off-the-shelf AR optics, furniture, and slings.
100% safe platform
An ATF-classified non-firearm that cannot chamber a live round, and it ships to your door with no FFL.
Pennies per round
About $0.07 per round, versus $0.29+ for live ammo — so the platform pays for itself after a few months of regular training.
Built to last, trusted to perform
Forged 7075-T6 receivers and US-made steel internals, backed by a 5-year warranty, and fielded by U.S. military and hundreds of law enforcement agencies.

"With the UNIT9 Training Pistol now paired with the UNIT4 Training Rifle, we have the best non-lethal firearm training system in the world. I live in an average American neighborhood and with this system I can train any time and anywhere. I am averaging 90 rounds of pistol and 60 rounds of rifle every day!"
"An amazing training tool — also good for instructors to use to help new clients on their journey into this space. Very well built and suggest buying an extra magazine or two. Crisp slide and trigger."
"I’ve had this for a little over a week and set it up like my personal rifle I carry on patrol for my agency. Seamless in its controls, function and has been a huge benefit in my training and presentation as my agency’s Active Shooter instructor. I’m so impressed that I will be showcasing it to my Administration for purchase to add to our training kit."
