Cant press out the firing pin pin
07/21/10 at 01:51:09

Ok, so I read the manual and watched L4E dissasembly video on youtube and encountered a problem quickly.

I cant press out the Firing pin pin from the bolt carrier. I'm trying to push it out from the right side of the bolt carrier as the manual states but nothing is happening, even after putting a good amount of force.

Am I missing something? does the bolt on the bolt carrier have to be in a specific position before pressing down on the firing pin pin or something? I tried for like 20 minutes and no luck.

Sorry, still a newb but just doesn't seam right. should be such a simple task. I have no problem removing the assembly pin above the pistol grip so I wouldn't think I should have a problem with the firing pin pin unless something is wrong. could still be a newb mistake. Please help

Well, that's a weird one.

It definitely should work just as shown a little over a minute into the PLR-16 disassembly video (link in the PLR-16 FAQ).

The firing pin pin has a flange on the left side, so it must be pushed out from right to left as shown in the video. It has an O-ring to add a bit of friction, but it's not a very tight fit. It almost but not quite falls out on its own. Very little force is needed to push it out.

The O-ring can dissolve in solvents, so I never use any strong solvents in that area, just a little bit of RemOil. It's possible that a strong solvent could have melted the O-ring and glued the firing pin pin to the bolt carrier, but it seems very unlikely that it would bond so tightly that you couldn't push it out with the stem of the operating handle as shown in the video.

Other than watching the video, pausing it, and making sure you're doing everything exactly as shown... I'm stumped. This definitely should not be a problem.

On the plus side, there's a current thread on the RFB forum describing how easy it is for the firing pin pin to fall out and become lost. At least you don't have that problem.

Bent firing pin can cause that to jam. Does the firing pin have any play? If the firing pin has play and isn't tight, then the most likely cause is pressing the wrong side, or the oring somehow came apart or bound up or something. If you're positive you're tapping the right side of the pin, hold the assembly in a vice and gently but persuasively tap it through. Inspect the firing pin for straightness and inspect the pin for damage, including the oring.

Maybe the whole left/right thing is getting confused? If you look close at the fp pin, one end of the fp pin is obviously larger than the other end. Make sure you are pressing on the small end, not the large end. Good luck.

I wondered about that myself, but it seemed too obvious, even given the fact that obvious stuff isn't always obvious to me when I'm in unfamiliar territory. I didn't want to inadvertently insult anyone.

Good luck.

Definately is the right side that I was trying to press out on. Made 100% sure that I was doing it right and even after watching L4E's disassembly video I knew I was doing it the correct way and was having no luck, so I took a hammer and nailed it out (Dont know if I should of done that) but it finally came out and nothing seamed to be damaged (firing pin pin, firing pin)

Well when I try to insert the firing pin pin back in, It gets really tight at a certain point (like halfway) and I have to nail it back in.

Im wondering if this has happened with anyone when their's was new and maybe it just needs to be broken in?

Hope im making sense because had a little bit to drink tonight Wink

(not handling the gun at the time either Wink

)

Like I said, it should be a very simple task to push out the firing pin pin out the correct way with no problems. I have no problem pushing out the assembly pin, for what thats worth. even though thats a double sided operation

. I just know something is not right and called kel tec and they said to send in the bolt carrier but I dont want to do that yet. What are your guys's thoughts??? I can now remove and reassemble the firing pin pin using a nail and a hammer. should I wait it out or send to kel tec?

I'd send the bolt carrier, complete, to kel-tec. The firing pin should drop in and out freely with no binding whatsoever. If the fire pin is binding up inside the carrier, it's a safety issue.......could cause a slamfire, may even keep doing it until the mag is empty. Sounds like the bolt carrier is slightly out of spec or your pin is bent.

You should never need to use a nail and a hammer to remove the firing pin pin. Something is seriously wrong. I'd take Kel-Tec up on their offer and send in the bolt carrier assembly. This is a critical assembly and it needs to work correctly.

Just out of curiosity, can you tilt the bolt carrier assembly and have the bolt slide in and out of the bolt carrier as demonstrated in the video? With the bolt back inside the bolt carrier, can you push the firing pin on the back and have it protrude from the bolt face, and push on the firing pin sticking out the bolt face and have it poke out the back of the bolt? In other words, is the firing pin free to move back and forth with the firing pin pin inserted? If these parts don't work exactly as designed, there could be some serious safety issues. I'd send it to Kel-Tec and let them ensure that it operates properly.

It sounds like the firing pin pin is a bit too large, the firing pin pin hole is a bit too small, the notch in the firing pin is a bit too shallow, the hole for the firing pin pin is incorrectly located relative to the firing pin channel, etc. None of these are going to be easy to fix at home. I'm not sure why this problem wasn't caught when the PLR-16 was assembled. Hopefully, the functional testing verified that it fired safely and didn't slam fire or go full auto, but the problem needs to be corrected.

Be sure to put a good written description of the problem in with the parts you return to Kel-Tec, along with your name, address, phone number, and PLR-16 serial number.

Yes to all these questions. im pretty familiar with the bolt carrier now and everything seems to be working fine but the freaking firing pin pin just seems to be to large or something? the bolt does slide in and out freely and the firing pin is also moving freely and yes it protrudes out the bolt face a (tiny bit) as it should probably should with the bolt inside the carrier?

I took 2 shots today because I was anxious and it functioned properly.

So do you guys think I should wait it out or send it in like Eric said

How can I explain this, I removed the firing pin pin by tapping it out again. It seems like the O-ring is up against the sidewall, like it is not flush. so if i were to try to press the fpp out, the O-ring is just getting cought up on the inside of the wall, Like it's not coming straight out. Hard for me to explain but I hope it makes sense.

Im very disapointed Kel-tec did not catch this problem. If they would have just tried to disassemble the bolt carrier, they would of immediately found it impossible to press out the firing pin without force. Angry

Very upset right now. I do love this gun already and it's not a major issue (or maybe it is) but a big hassle for me, that I dont feel the need with a new gun and a very easy problem to have caught. Tomorrow Im taking it back to the gun shop/Gunsmith (which is 40 mile drive) and have him take a look at it and most likely have him send it in to Kel-Tec. I was gonna just send in the bolt carrier to kel-tec myself through usps but I just want to talk face to face with a professional about the problem. Ill keep you guys updated.

It happens Pistolman, don't be do down on it. I've dropped 2K for an AR before...........only to discover it could shoot around corners.........and that was an "as is" purchase. Kel-Tec will take care of you, just have a bit of patience.......it's a good gun and well worth sorting out.

I am staying positive about the situation Eric and just an update.

I called Kel-Tec and explained the situation and they said to send it in. I asked what the time frame was to get back the bolt carrier and the guy said it is typically a four to six week turn around.

So I called the gunsmith, also the guy I purchased the gun through and he said to bring it on in and he would take a look at it before sending in to Kel-Tec, which I already planned on doing.

So when he took a look at it, he concluded that Kel-Tec did not drill the hole properly in which the O-ring sits in and that's what was causing the firing pin pin to not come out. So, when I tried pressing out the pin, the O-ring would get caught up on the wall, instead up the whole pin coming straight out. The pin itself is fine. Not bent or anything.

Im not sure exactly what he did to fix the problem but he worked on it for about 15 minutes and said it was fine and no need to send in to Kel-Tec.

I am now able to press the firing pin pin out with the operating handle and insert the pin back in and the O-ring does click in to place.

I just hope I wont have any issues with it down the line but it does seem to be up to spec now.

Thanks for all the help. Does anybody think I should still send it in for any reason?

Awesome. Sounds like you've got a good LGS. Whether you want to send it in to Kel-Tec still for peace of mind is up to you, but it seems like from your description that it's solved and there is no issue with the firing pin. Let us know how it shoots;-)
