The Kel-tec RDB is just about the best bullpup on the market in terms of cost vs performance. After a few hiccups, it seems Keltec has finally gotten QC under control and come up with a fantastic design for urban combat.
The Keltec RDB is a DOWNWARD ejecting, long-stroke piston driven firearm (like the ultra-reliable AK) with an adjustable gas system and a very smooth recoil impulse.
The down-side? The exceptionally ugly plastic rail. We fixed it. Introducing, the Kel-Tec RDB "Raptor Rail". The shell is made of 6061-T6 aluminum, the 4 piece mounting adapters under it that mate it to the rifle out of 7075-T6, hard anodized black, with M-Lok slots for accessories on either side and the bottom, QD mounts left, bottom, and right at the rear of the rail, and cooling vents elsewhere, this aggressive-looking but extremely functional rail is exactly what the RDB needed!
