Perfect size for what I wanted. Short, light and easy to move around with but still feels like a quality build. The FRS is alot of fun and everything ran good from the start.

This little 10.5 is a blast. Nice and compact without feeling cheap or thrown together. The MLOK handguard feels good, Warhammer handle is a nice touch and the Atrius setup is crazy fun. Ran good right out the box.

Finally got this thing out to the range and didnt want to put it down. Compact, loud and just plain fun to shoot. No problems with it so far and the Atrius selector is wild.

Ive owned a few AR pistols and this one surprised me. The handguard feels great and the controls are laid out nice. Fit and finish is better than I expected for the price. One Horse did good on this one.
