Picked up a Kel-Tec RDB

I did some trading last night at Surplus City in Feasterville, PA, and came home with a Kel-Tec RDB 5.56mm bullpup rifle. (I actually went there with the intention of ordering an FN PS90. Maybe next time.) SC was asking $950. I traded in my CZ-52, Bulgarian Makarov, Ruger SP101, Pietta SAA, and Springfield XD-9, none of which I'd fired in years. He gave me $1000 trade in value, so I also got 500 rounds of CCI .22 Short HV to run through my Remington 550-1.

This is my first bullpup rifle, unless you consider a Beretta CX-4 Storm a bullpup. (I guess it sorta is.)

Kel-Tec gives the OAL as 27.3" with its 17.3" barrel. The weight unloaded is 6.7 lbs. The barrel is 1:7" twist. There's a long, T-marked M-1913 Picatinny rail on top but it comes without any sights. I am debating what kind of optic to mount, but it will probably be something along the lines of a 1-4x variable, not just a red dot.

The RDB is a new design, although the bolt itself is very Stoner-ish and it takes AR15 magazines. It came with one 20-round MagPul P-Mag, an owner's manual, and a sling.

There are numerous sling mounting points for the hook-style attachments. In the pic above I had it mounted as a 2-point sling but I later switched it to a single-point using the swivel located in front of the middle takedown pin.

It's a long-stroke, gas piston design. The gas is adjustable to account for variations in ammo or the amount of crud in the gun. However, reviews I've seen state that very little fouling gets into the action. Empties eject out the bottom, through a port behind the magazine well.

The action is very simple and breaks down with only something to drive out the takedown pins. (They may loosen up over time.)

As a southpaw, the best part to me is that it's totally ambidextrous except for the HK MP5-ish charging handle. It can be reversed without tools. All I had to do was field strip the rifle and then put it in the other way when I reassembled. My initial impression of the rifle is that the ergonomics are outstanding.

Because of the long linkage between the trigger and the rest of the firing mechanism, most bullpups have lackluster trigger pulls. Not so in the case of the RDP. It's actually pretty good with some takeup but it's only around 5 pounds.

Between the adjustable gas system, the lack of fouling in the action, and having the ejection port on the bottom of the rifle so gas gets vented downward, it's supposed to be an awesome suppressor host.

In typical Kel-Tec fashion, they are scarce as hen's teeth, though. Kel-Tec announced it a few years ago but they just started shipping in 2016. They are still really hard to find in shops although there are a bunch on Gunbroker.

MAC posted a nice, in-depth review of a pre-production sample on YouTube in 2015:



I should be able to take it out in the next couple of weeks and will post a follow up after I am able to shoot it.
 
Congrats on a cool rifle. Honestly nothing that Keltec makes interests me much... except this rifle. I held one in the store the other day and really liked how it handled and balanced. The last thing I need is another 5.56 rifle, but if the reviews stay positive on this rifle, I'll probably wind up getting one as an SBR substitute to be shot mostly with a suppressor attached.
 
Please do share your thoughts after some trigger time, on paper the RDB looks to be a winner, but as with many of their products(even the good ones) they have a reputation to overcome.
 
I decided on an optic, an IOR Valdada 3x25mm CQB scope. It has very clear glass, an illuminated reticle that I like, I've shot with it on my Colt 6721 out to 200 yards (the longest range at my club), and it's built like a tank. I'm not going to worry about BUIS.

Range report to come...

I've tried bullpups suppressed; if you like the acrid gas discharge from a suppressed AR15 rifle your'e going really enjoy the bullpup experience :(
 
This rifle looked really interesting to me until ar15s could be found for under 4 bills.

The current ar15 price crash can't be helping keltec much, but then again I think they can't keep up with demand so that may not matter.

The survivor model looks very interesting as well although it's not out yet...

Have always had a certain fascination with bullpup designs. Really like the clean lines and overall compactness of the RDB. Awaiting your range report to see how well things go with it.

According to everyone who has run an RDB suppressed, it's about the best suppressor host they tried. Because of the gas piston design (compared with the AR's direct impingement) very little gas gets back into the action. And what little gas does get back into the action is vented downwards, away from your face.

Kel-Tec's rifles are sufficiently different from AR-15s that they aren't direct competitors. In my case, I already have 4 AR15s so it's cool to pick up something different.

From your photos everything looks well made and with a decent finish to it. Was the field strip fairly easy and relatively straightforward?
 
Thanks for the continuing info & pics, but ... you're killing me here, Dave. :)

For years I resisted the RFB starting out with an opportunity to get one, early on, for a great price. To avoid that one, I posted about it in one of the Forums so that someone else would quickly buy the thing before my resistance crumbled ...

The acrid fumes are not the result of the gas from the DI system in my experience. They are the result of the back pressure caused by shooting suppressed. The gas will come back, it will escape the open bolt. The amount of gas coming to the attention of the operator's nose and eyes is proportional to the number or rounds fired within a period of time.

I'll stipulate to being particularly sensitive to the gas, I wish I weren't.

I'm skeptical about gas being vented in the same direction as brass is; my RFB sure as heck didn't push the gas out front.

To field strip you drive out two pins, which allow you to separate the upper and lower. One more pin holds the handguard on the barrel. The owner's manual states that you should be able to press them out with finger pressure but mine are too tight for that. I used a small hex bit in my screwdriver as a punch to pop them loose. The point of a bullet would work, as well. I'm ok with requiring a tool since I'd rather have the pins a little snug than too loose.
 
Congrats on the purchase. I had my eye on the RDB for a while, but the prices were too high, IMO. If I'm not mistaken, they raised the MSRP on their web site. I thought the initial reports were that it would be around $800-850. Now MSRP says >$1200. I've seen a glowing review of the newer RDB-S model, too.

I love Kel-Tec's innovation, but I always wait a bit to see about the quality, longevity, and real world user reviews of their products. Plus, I don't have a choice but to wait since their availability is always low. I wish they would produce enough to get them into more local gun shops so that we can actually see and hold one before buying it. I'm eager to hear about your experience with yours.

Yes, snug fitting pins are always preferable to ones that are bit too loose.
 
Lol, at nearly half the price of an AUG or Tavor folks are still complaining about the price. Part of why I'm so interested in these is because they're the first reasonably priced rifle caliber bullpup.

1) Price is around 900$
2) There's plenty on Gunbroker
3) If you only buy at gunstores, you're stuck with only the biggest brand names

It may help your resistance to consider that a tipping bolt is not great for accuracy anyway, and a bigger RDB in .308 is all but inevitable in a couple of years.

What about the RFB? I'm not an expert but it seems like a slightly enlarged RDB and in 308 like you mention.
