    With the highest of hopes and after doing a lot of research here and other places, I purchased a new RFB last weekend. This weekend I got to go out and put it through its paces.

    To say the lease I am VERY disappointed. I adjusted the gas valve per the manual and that went great, just as written. Then I loaded up a couple of rounds and did a little sighting in. Good accuracy from what I can tell so far.

    The disappointing this is that it will not feed any more than two rounds from the magazine. If I put 10 rounds in it feeds the first two. If I put three rounds in it feeds the first two.

    I found that if I reach inside and pull the bolt back down it will again feed two rounds. I also found that the purple and blue items in the picture below (304, 305, 308) are VERY hard to rotate. I am not a smithy but have been at this game for over 40 years. This seems very odd to me as there is a very small spring in there to return them to a neutral position. It could also be a bad magazine but I am not suspecting that.

    My disappointment comes from spending 3 weeks salary on a very neat idea rifle and barely getting 20 rounds through it before it has to go back to the factory. At least my dealer was willing to facilitate that.


    My recommendation if you are looking to buy one of these is to get a dealer that will allow returns. I would have gladly returned this in trade for an AUG but did not have that option, so may be stuck with a very expensive boat anchor that will look good hanging on the wall. If a rife is not about 100% reliable then it is of no use to me. I may be wrong but at this time feel I made a BIG expensive mistake.

    Sorry you are having troubles. What you describe with the extractors(304,305) is norma. They are stiff to move without a shell between them as they must have inward spring tension to grip a case. Without a case in between them they rub on the side of the bolt. Snap a case into them and they should snap to the upright position all by themselvs, even a loaded round snaps up smartly if they are working right. If they didn't, the rifle wouldn't cycle at all.

    SO where exactly does your bolt stop when trying to load the second round? Most FTF issues are magazine related. It sounds like you didn't have a second mg to try? It being a staggered magazine, did it perhaps only feed the right hand shell or the left? Could the leading edge of the bolt possibly been hanging at the back edge of the mag(bolt runs down into the mag thru a channel at the rear).

    Thanks for the explanation on how the bolt works. That makes a lot of sense. The rifle only came with one mag and even though I had a couple of Thermold magazines they were so bad that the followers would not even move back up on their own, thus I did not even try them in the rifle. I will see what/if the dealer finds and then may just have to get some good old FN metal mags that I know work fine. Sure wish the nanny state would let us have decent sized mags these days. :(

    The rifle would fire the first and second round out of the magazine and then would not pick up the third. The bolt stopped fully in battery but had not picked the top round of the magazine up.

    What is the track record on the street for the RFB? I'd NEVER buy any Kel-Tec firearm that doesn't have a pretty solid reputation. That's the only reason I just picked up a new Gen 2 SUB2000. 300+ rounds through it so far without a single hitch. That said, I'm truly sorry your RFB isn't working out well. I know how that feels.

    If it loaded a :quote:nothing:quote: into the chamber, 100% a mag problem.
    If you're having to use "shortened" mags, that makes complete sense.
    As for the good-ol' FN metal mags, I use nothing but those in my RFB and it don't miss a beat:D.
    For the love, stick a 'known-good' mag in it, dial the gas in, and shoot it, before tearing it into a million pieces.
    The best gun in the world will shoot like crap with a bad mag in it:wall:.

    I am also thinking it is a mag problem. The stock mag is nothing very impressive and of course they had to modify it to a 15 rounder at the shop before sale. (yea don't get me started:mad:) So that is probably the issue. I will probably need to get some Magpul mags for it or just some good old FN metal mags.

    Thank you all for the information and I am feeling a bit better about it. :D

    Something to watch while you're mag shopping:

    Mine shoots like that. The only pain it gives me, is in the wallet:D.

    I SO wish Magpul made FAL mags... I have asked, but they would neither confirm nor deny that a FAL pattern mag was even in the works...

    If your mag had to be modified to be legal(pinned/riveted) it is possible that that mod done incorrectly is restricting the spring travel.

    Thermolds that the shell followers wouldn't even come up on? Pull them apart and clean them... Only time I have had a problem with one was because it was full of crap, but that is true of any mag:)

    I'm with Ron, definitely a mag issue related to whatever means they used to limit your magazine.

    I use the Thermolds and the only issue I've ever had was not being able to seat on closed bolt when fully loaded (5 for us poor Canadians). I've since fixed that. With the steel magazine that the rifle came with and one more I bought i had issues occasionally.

    I think you should stop trying to be Donald Trump. One mag and your off bad mouthing the company & the rifle. :no: Then you hold back the mag mod details till the 6th post in the thread?:wall: Uh, how about a "apology?"

    I had a similar problem. Occasionally I could get 4-5 shots, but usually 2. The bolt would jam open, and partially crush the ejecting brass. The next bullet was ready to chamber, but the bolt was held back by the jammed ejection brass. Different mags made no difference. Finally drove to the cocoa factory the gunsmith there found the ejection ramp was bent and replaced it. Shoots wonderfully now.

    hello everybody , I'm french and i so sorry by advance for my low level in english , but I'm a very happiness RFB owner.

    after more 3000 rounds shooted with this one I have learn a lot of things on it.

    firts of all , you must know that the RFB out of the box is not reliable. but no panic , first step, change the magazine by a thermold and second step you must generusly lubrificate all mechanics mobile parts during the running in.

    the setting off gaz systeme must be done round by round, ammo by ammo to find just the moment when the bolt stay back when the magasin is empty and after you must increaise of 5 clicks the gaz system .

    for the first 300 rounds , i proceed to a clean-up and lubrification all each 50 rounds shot and from 300 to 1000 rounds a clean/lubrification all each 100 rounds shot. Now I do a fast cleanning after two shooting sesions ( i shoot aproximatively 100 rounds by sessions )

    you may be sure, that if you proceed like that, your RBF will have normals loading cycles.

    on my RBF know it's very rare I have a reload issue but this was not the case when this one worked with metal magazin and without a good setting of gaz system and a good running in.

    another advise no change frequently ammo type because this obligate you to set another time the gaz system.

    Be sure to put the RFB in your will&testament. Years from now, there is no telling what it will be worth over there.
    Thank you for taking the time to study it before posting: "I Can't Get It To Work! crying.gif ":no:
    As you have found out, it does work very well with a little care and can produce great firepower.
    If you need help, let us know.
    :kiss: ...(it's a French thing:))
