What sets it apart
The DB10 runs a direct impingement system with a mid-length gas system. It has a forward assist, a dust cover and a manual safety. The trigger is mil-spec. The barrel is threaded and wears an A2 flash hider. It feeds from a GEN 3 PMAG with a 20+1 round capacity.
The handguard is M-LOK, so you can add a light, a sling mount or a grip where you need it. The upper has an integral Picatinny optic mount. The rifle has no sights, so plan on putting a scope, red dot or set of backup sights on it. The stock is a MOE Carbine in blue Cerakote, paired with a MOE K grip.
This rifle fits shooters who want a carbine-length .308 for range days, training or hunting setups. It also suits anyone building out a platform with their own optic. Good companions include an optic and mount, a sling, extra GEN 3 PMAGs, M-LOK accessories and a padded rifle case. Pick .308 Win ammunition that matches how you plan to use it.
