Radian Weapons AX556 Stripped Billet Lower, 223 Rem/5.56mm, Ambidextrous, Black

The KSG is Kel-Tec’s first entry into the shotgun market.  The size, shape
and design are similar to the currently available Kel-Tec RFB rifle, but
the KSG ejects downward, instead of forward.  The KSG weighs 6.9lbs and
is as compact as legally possible with a 26.1″ overall length and an
18.5″ cylinder bore barrel.  Even with this compact size, the internal
dual tube magazines hold an impressive 12 rounds of 12 gage 2-3/4″
rounds (6 per tube).  The simple and reliable pump action feeds from
either the left or right tube.  The feed side is manually selected by a
lever located behind the trigger guard.  The lever can be positioned in
the center detent in order to easily clear the chamber without feeding
another round from either magazine.  A cross bolt style safety blocks
the sear, and the pump release lever is located in front of the trigger
guard.
The pump includes an under Picatinny rail for the mounting of a
forward grip, or a light or laser.  The included top Picatinny sight
rail will accept many types of optics or iron sights.  Forward and rear
sling loops are built in, and a basic sling is included.  The soft
rubber butt pad helps to tame recoil.
