Frequently Asked Questions

What are the main advantages of suppressing the Kel-Tec RDB?

Suppressing the Kel-Tec RDB significantly reduces felt recoil, making it much more manageable. Its downward ejection system also prevents gas and brass from being ejected towards the shooter's face, a common issue with other bullpups when suppressed.

How do you adjust the gas system on the Kel-Tec RDB for suppressed shooting?

The RDB has an adjustable gas knob on the front. For suppressed use, you typically turn this knob down (clockwise) to reduce gas pressure. The video suggests starting with 11 clicks down from the factory setting for 55-grain ammunition.

What are the risks of improperly adjusting the gas system on a suppressed RDB?

If the gas system is turned down too far, the RDB can malfunction, leading to jams like double feeds. In these instances, the bullet tip can jam forcefully into the feed ramp, making clearing difficult.

How does the suppressed Kel-Tec RDB compare in size to a standard AR-15?

Even with a suppressor attached, the Kel-Tec RDB remains considerably shorter in overall length than a 16-inch AR-15. This is due to its compact bullpup design, which places the magazine and action behind the trigger.
