The Get M400-TREAD PISTOL is a serious defensive firearm built for shooters who want a compact, reliable AR platform without the hassle of a tax stamp. Chambered in 5.56 NATO, it’s ready to run right out of the box with a 12.5-inch barrel and a free-floating M-LOK handguard. We’ve had this in our catalog since early 2026, and it’s been a consistent seller with solid feedback from customers who trust it for home defense and range work. On our scale, it weighs 1.1 oz — light enough to maneuver in tight spaces.

What Buyers Ask
Does this ship with a brace or a stock?
It ships with a pistol brace, not a stock. That keeps it legally a pistol, so no NFA tax stamp needed. You can shoot it as-is or swap the brace for a stock if you go through the proper paperwork.
Will this run with steel-case ammo?
We’ve tested it with brass 115gr and 124gr, and it runs great. Steel-case ammo can be less consistent, but many customers report it cycles fine. Just expect the occasional hiccup with weaker loads like 147gr subsonic.
Can I mount a suppressor on this barrel?
The barrel is not threaded from the factory. You’ll need a gunsmith to add a muzzle device or check if your suppressor has a direct-thread option that fits the 1/2×28 threads. We don’t recommend it without professional installation.
