KelTec RDB-C Hunter Rifle 5.56 NATO 10rd Black

The KelTec RDB-C Hunter is a semi-automatic bullpup rifle built for compact handling and practical field use. Its downward-ejection system makes the platform effectively ambidextrous while keeping ejected cases and gas out of the shooter’s line of sight. The rifle features a smooth trigger, an adjustable gas piston for tuning with a suppressor or varied ammunition, and an ergonomic forend with a swivel-stud bipod mount. The RDB-C is optic-ready and designed to accept AR-pattern magazines for broad ammunition and magazine compatibility.
