I own three Kel-Tec firearms, all have been good. I particularly appreciate the fact this gun is ambidextrous, I am left handed.

Does it include the angled foregrip?
Chris on Feb 27, 2019
BEST ANSWER: No an angled fore grip does not come with the rdb they provide a sling
Does the bullpup require special mags?
Tyler on Mar 25, 2019
BEST ANSWER: No, the RDB uses regular 5.56/.223 mags. I have personally only used 10, 20 and 30 round mags and the 20 round works best for me.

What took me so long?
If you’re like me you have probably been interested in the RDB. Unfortunately for me my friends never got pirchased one so it was up to me. Overall I don’t regret it at all.
Cons: it is different and therefore your weapon layout and manipulation will have to be changed to run this. It isn’t an AR so don’t expect it to be. Just like running an SBR there is a fair amount of gas in the vicinity of your face with the exception of none coming from the ejection port. Dis/ass is very different from an AR so read the instruction manual. Not kidding. If you’re into it your LEGO accessories will have to be given some serious thought to layout since the top rail is just good enough for a LPVM scope. The sling attachments suck. Not by functionality but there is a constant rattle since you’ll have to use hk hooks which are metal grasping a plastic fore end. It is almost a gymnastic endeavor trying to physically and visually verify empty chamber.
Pros: the trigger is consistent and smooth for a bull pup carbine. Mine is pretty damn accurate using a fixed 3x prism I shot 5 groups after zeroing and group size ranged from [email protected] to [email protected] using wolf gold 55grain. The recoil impulse is next to nothing and feels much better than regular layoutted? Piston guns. This thing fits in a case designed for SBRs or broke down ARs. Most importantly, if you’re like me, your friends don’t have one. Well except the one that just ordered one.

Best bullpup for the money on the market
Being a lefty, most bullpup firearms eject the brass in my face. This one has a rather ingenious downward ejection which makes it truly ambi.

adjustable gas for shooting suppressed... awesome. Works well. And speaking of shooting suppressed... being a lefty the gas blowback into my face on most AR's is just awful when shooting suppressed. This has NONE... its just awesome.

cheap plastic handguard can be replaced with a m-lok (much more useful and comfortable.

Trigger is outstanding and function is flawless after 500 rounds or so... would highly recommend...
This does NOT come with the magpul foregrip as showing in the picture... it should be grayed out as well.
