The RDB – 1200 Rounds Later

Last October I found an RDB at my local gun store; 4 of them to be exact. I have been reading about them on /k/ for a few months and seeing reviews and, despite Kel-Tec’s reputation, I thought it was a really interesting gun and apparently they were rare at the time. I picked it up for $1100 out the door, a good price for the time (pre-election), but not so great now. Initially, the gun really impressed me; almost no recoil impulse due to the adjustable gas system, downward ejection means anyone could shoot it (don’t use it for 9 hole, however), and the overall length was so compact you could move it freely even in the smallest of vehicles. With an EOTech on it, I could hit steel at 100 yards one-handed; it was perfectly balanced on the grip with a full 30 round mag. The trigger was actually very, very good. The trigger weight is 4.5 pounds with maybe a little more travel distance than you would want, but still miles ahead of other bullpups. I enjoyed the gun so much I decided to try to 3D model my own hand-guards for it to create my own MA5C, but more on that later.

At the 600 round mark, the ejector pin walked out while firing and bent as you can see below. This left the gun inoperable, so I looked up the issue and apparently early RDBs had this problem fairly frequently. I contacted Kel-Tec and they sent me a new one free of charge. They claimed the original pins were not thick enough and this new one would work just fine. The gun ran fine after that aside from a minor hick-up I didn’t notice until recently. One of the retaining collars for a takedown pin actually popped out at some point and I hadn’t noticed, so the pin wasn’t totally secure. It wasn’t really a problem because it never fully walked out, but it moved more than it should have and wasn’t secure when taking down the rifle.

At 1000 rounds the firing pin broke. The tip of the firing pin actually broke as shown below. Never, at all, under any circumstances, should a firing pin break within even 5,000 rounds. Angry that I had to talk to Kel-Tec again, I spoke to some others who knew more about machining than I did and they told me it was an issue of treating and that the firing pin was probably brittle. This may speak of Kel-Tec’s manufacturing processes when it comes to making their rifles, as they are a plastics company first, and foremost. Kel-Tec sent me another free of charge and again, I had a functioning rifle.

I had hoped I was done with the problems this gun had brought me, but again, at 1200 rounds, the ejector pin walked out just as it had 600 rounds ago. Not only that but while trying to strip the paint from the gun (do not try to spray paint when it’s humid out) the water used to rinse it off actually rusted the screws holding it together and part of the trigger springs. That is just unacceptable. At this point, I was fairly angry and disappointed in Kel-Tec. I contacted them to voice my issues and they told me to send the gun in for a full upgrade because “there had been many improvements since the serial number series I bought was released”. I sent it in, they fixed it, and they sent it back within a week. Good turnaround time, but I shouldn’t have had to send it in in the first place. I haven’t had a chance to take it out and make sure it works since I got it back, but I’ll be heading out here soon to make sure it does what it should: shoot.

Would I buy this gun again knowing what I know? Not right now. Would I buy this gun in a year or two when the issues get worked out? Maybe. I bought the gun because I wanted a bullpup that both looked cool and didn’t face many of the problems that more popular versions did like mushy triggers and bad ejection. Kel-Tec solved these problems but introduced their own. The RDB is a very cool gun and I have plans for it in the future, such as the aforementioned MA5C handguard and top rail (I’ll make a post when it happens), but at this point, I would much rather have the money I spent for it than the headaches it has caused.

    So what im getting is it was a great gun, but with problems even high points shouldn’t have. minor mistakes that could cause major issues. Im gonna pick one up for $750 and see how it works. Its gonna be mainly for me so my father can use my dissipator on the hogs. Hopefully I don’t run into any issues.

      I picked one up recently and in less than 200 rounds it is inoperable. I emailed their support 2 days ago and no reply. I will call tomorrow. First round jammed, but figured I wasn’t charging it properly. The next 100 rounds went uneventful. This past weekend I had another jam 20 rounds in. Thought nothing of it and cleared the jam. 10 rounds later, another.. but now noticed the bullet was pushed back into the shell. This worsened until the gun would not fire at all. I have only had it for 2 weeks and now I cannot use it. The gun store threw their hands in the air and said call the manufacturer. Would I buy it again? Idk. It has potential but if it doesn’t shoot, what good is it?

    So did anything ever happen to the RDB? Mods, upgrades, repairs, mothballs, returned, sold?

    I really want the Kel-Tec RDB & RFB to succeed & at least be decent choices for a less expensive & ambidextrous BP. Pretty much all other BPs aren’t ambi & cost some bling. Nearly all have not so good “go buttons”.
    I will keep researching & see if it has improved any with the current generation & look for other options as well.

    Kel Tec is, no pun, hit or miss. Jams, miss feeds and F to Fr are infamous. At least not a J68. Only got 5 rounds out before bolt broke.
