Today I used Tula steel cased 62 grain and 55-grain ammo, along with Federal 55 grain ammo. With the Federal, the bolt locked back without having to make any gas setting changes. With the Tula, five clicks to the left and presto worked perfectly with all 3 types of ammo. I used Gen 2 &3 P-mags, surplus steel mags and Hex mags with no issues except for one of my P-mags which must be a dud because it failed on my AR also, it failed to seat properly on both guns. Other than my one P-mag issue, I experienced no problems at all. I was apprehensive at first about the gas settings but it's super easy to adjust. I've never had any experience with adjustable gas systems until now. The Primary Arms 1-6x scope was fun and easy to set up and made shooting much more enjoyable.

Nice range report. What distance was that target?

I've fired my RDB once so far. 31 rounds of 55gr Federal Lake City. The first mag was a Thermold mag that has been loaded for 5 years. The first round fired just fine but the gun jammed on the second round. After clearing it, I found the bullet had been pushed back into the cartridge. I removed the Thermold mag and loaded a GI mag that had been loaded for 5 years. All thirty rounds fired without issue. Trigger felt good - not especially light or heavy and less scratchy than the factory trigger on my SCAR 17. Accuracy was just fine at 25 yds with a Burris FF3. Fun gun, I look forward to trying it out this weekend with an MRO at 50 and 100 yds.

Rob17- The target was at 50 yards.

Great range report! Three things...
1) I'm ecstatic that she runs steel!
2) Great accuracy!
3) Is this the 1:7 twist?

I had mine for a couple weeks and finally got to shoot it Sunday. I was pretty satisfied with the first 2 20rd mags and then it went to crap. Every shot became a double feed. Tried the 2 Colt 20rd aluminum mag and then a Pmag.
All the same, fire a round and get a double feed.

I moved the gas settings three clicks and it functioned great for almost the whole mag. I could feel the bolt lock back so I thought I ran the rifle empty. I drop the mag and I still have 4 rounds in the mag. I hit the bolt release and nothing.

Gonna take it apart, clean and lube it, read the manual, and try again. If the same thing, it's going back. I was pretty bummed.

Don't give up yet Sharkey! What type/brand of ammo are you using? Try this, load only one cartridge in your magazine, fire 1 shot and check to see if your bolt locks back. If it doesn't, turn you gas adjustment dial 3 clicks to the left and repeat the single cartridge in your mag and repeat adjusting your gas setting until it locks back. 5 clicks to the left and I was able to shoot Tula steel and Federal brass with no issues. I think elevation may play a role in the gas settings, I'm barely above sea level here in Louisiana.Take your time and write down how many turns you make, and eat type of ammo used.I also. marked my dial to make it easier to see which direction I've turned and just how far I've gone.

Cubanb- yes it's a 1:7 twist!

I was using some late 80's Israeli ammo that comes 20rds in little cardboard boxes.
Dumb question, when you say click to the left, is that while shouldering it? I will try your suggestion and see if that works. It's raining a lot here so probably be next weekend before I cn hit the range again. The RDB is sitting on the counter waiting to be cleaned and lubed mocking me.

Yes, looking at the gas knob while muzzle is downrange. If you have not moved your charging handle, it should be on the left hand side of the rifle as well.

It's also how I remember to adjust the gas knob. "Rotate the knob towards the charging handle for a greater charge of gas.":rayof:

There are instructions and a diagram at the bottom of page 7 and the top of page 8 in the RDB manual that say how to adjust the gas regulator. If the gun is short stroking and not feeding or jamming increase the mount of gas to drive the bolt carrier more to the rear. It's interesting to note that the manual says to move the gas regulator one notch higher for reliability after you get the gun operating properly.

Unless you are left handed then it is the opposite! Read the manual and look at the diagram on page 8.

Reread my first paragraph.

Let's stick to the owners manual. Left, right, up, down, forward, back it off, clockwise if you look through the sights, or counter clockwise looking down the barrel. Reverse if you are left handed.
See how easy it is to confuse directions?

 

[sharkey]

I'm gonna call KelTec tomorrow and see what they say but I am pretty sure mine is gonna go back.
I stated the bolt "sticks" in the locked position without the aid of the charging handle being in the locked position. This occurred after I turned it counterclockwise 3 clicks on the range (set up for right handed).

I dissassembled it Saturday after watching 2 videos on it, lubed it, and then put it back together and the bolt still fails to return forward to the chamber. It goes forward when I tap the barrel on the ground but I'm pretty sure you aren't suppose to do that.

I believe the operating rod connected to the bolt and spring are defective somehow.

Took my new RDB out Saturday and got it sighted in at 50 yds with my cheap little UTG red dot. Used some 55 grain reloads from a member of my range club and had to adjust the gas all the way up but then it cycled every time.
Accuracy is great for my old eyes and I do love the way it shoots. May have to sell my AR now!

Just took my rdb out tonight and had a double feed that really jammed it up and multiple light primer strikes. The light primer strikes felt like the trigger was only about half of what it normally is. Played a little with the gas settings but it kept happening. I'll have to go back and play some more to see if it clears up and if not Mr. George K will have to take a look at it and tell me what I'm doing wrong.

I called my contact at Kel Tec earlier in the week to see if they could talk me thru the problem. She put me in touch with Sean the Customer Srvc Mgr who stated they would prefer just to look at it and fix it. They sent me a return label and it went out today.

Hopefully it is a simple fix and I get it back quickly.

 

[MarkB1]

Please post the serial numbers of those RDB's having some problems. "X" out the last number of the serial number for safety. It may be that some of the problems are located in a block of serial numbers. This would be helpful for the rest of us that might have problems. This may not matter at all and it is just individual guns that are having problems.

 

[sharkey]

I believe it is X3**. I'm guessing I will hear something this week and hopefully get it back next week. Kudos to Janis and Sean for contacting me so quickly.

In the meantime, here is some gratuitous gun porn. Pulled it out yesterday. I worked a contract job Sat. Night and took the M1 Carbine and I should have taken this instead.

I just sent mine back today. It fired around 15-20 rds from a 30 rd pmag and then started double feeding. It turns out the extractor was missing the retaining pin LOL.
Here's hoping they get it fixed and get it back to me post haste. Sending out a gun with parts missing is pretty bad QC if you ask me.

Can't wait to shoot it again without malfunctions.
KelTec needs some serious help with their professionalism. The designs are really great.
