The side-charging upper receiver provides direct access to the action and carries the marking "PAT. NO. 9,310,146." An enlarged ejection port exposes the bright-finish bolt carrier, and the rifle runs a direct impingement system.
The 24 inch stainless steel barrel is fluted, heavy-profile, and threaded, and it is fitted with a two-port stainless muzzle brake. This setup is designed to manage heat and recoil while maintaining rigidity. The free-float aluminum handguard includes a continuous top Picatinny rail and M-LOK-style slots for accessory placement.
Controls and furniture are AR-15 familiar: ambidextrous safety selectors, a fixed rifle-length A2-type polymer buttstock with a 13.5 inch length of pull, and a Magpul MOE pistol grip. The rifle feeds from detachable box magazines with a stated capacity of 5+1 and is supplied with two ProMag RM-5 5-round 5.56×45 AR-15 magazines. Note: .22 ARC AR-15s typically use 6mm ARC/6.5 Grendel–pattern magazines; the included 5.56×45 magazines may not provide proper feeding with .22 ARC.
Markings include "JB'S FIREARMS LLC • GRANTSBURG, WI" on the receiver and "JBS-15 • MULTI" on the lower. The magwell bears a stylized winged "JBFA" logo. There are no iron sights installed. Origin is the United States. The included Weaver Classic Extreme 4-16x50 scope is mounted in a Vortex cantilever mount.
