Description
This KelTec RDB-C Hunter is a bullpup 5.56 NATO rifle built for hunters and shooters who want a compact package without giving up barrel length. The 10-round magazine keeps it compliant in restricted states, and the bullpup design gives you a 16-inch barrel in a rifle that’s shorter than most carbines. We added this to our catalog in late 2024, and it’s been a reliable seller with consistently positive customer feedback — one customer drove 3 hours to pick this up instead of waiting for shipping. That says something.
Key Highlights
- Bullpup design: 16-inch barrel in a 27-inch overall length — easy to maneuver in tight spaces or brush.
- Top-loading magazine: No magwell means you can load from the top like a traditional hunting rifle, plus it’s fully ambidextrous.
- Adjustable gas system: Run suppressed or unsuppressed without changing parts. Just twist the gas block.
- Picatinny top rail: Mount optics directly over the barrel for a natural cheek weld and compact profile.
- 10-round magazine included: Factory-compliant for states with capacity limits. Ships with one box magazine.

What Buyers Ask
Will this work with standard AR-15 magazines?
No, the RDB-C uses proprietary top-loading magazines. It ships with one 10-round box magazine. Spare magazines are available separately and are designed specifically for the RDB platform.
Is this a California-compliant model?
This RDB-C ships with a 10-round magazine and has a non-threaded barrel option available, but this specific model has a threaded 1/2×28 muzzle. It’s compliant in many restricted states, but check your local laws for specific requirements like featureless builds or fixed magazine rules.
Can I mount a suppressor on this?
Yes, the barrel is threaded 1/2×28 TPI — standard AR-15 pattern. The adjustable gas system lets you tune the action for suppressed or unsuppressed fire. Just twist the gas block to the appropriate setting.
