X-Plosive is not the only one this has happened to, this has also happened to Major Damage.

you are so bleep bleep bleep!!!! CALL THEM!!! ask their techs!!!! just because you post some silly thread doesnt mean everyone at AGD has to drop what they are doing, sign on and type it up for you. how about YOU DO SOMETHING!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[X-Plosive]

christ.............first things first.





I exaggerated when I said half way. The bolt had gone in maybe an inch and a half with the spring. No the flange did not get in my barrel. It stopped a bit before the flange(whats the techinical term for that part?). I assume the bolt spring was okay it seemed fine btu i replaced it anyway just to eb on the safe side seeing how I have about 5 parts kits on me. Second I am not joking or exxagerating. What purpose would I have for this? Is it a conspriacy against the AGD products that i ahve poured tons of money into? heres the funny part. I took the body off. The barrel was still on. i kept pulling and it felt a little spring and reactice. The bolt and spring were in the breach of my barrel. I finally managed to push out the bolt and the spring through the back end of the body. the barrel then came off easily. It's not just a story and you all have WAY too much spare time on your hands to actually whip out a calipers and measure the diameter of a bolt spring.

I read a post a bit ago saying that someone's bolt and spring to stuck partially in the barrel because the nubbin was bent, broken or something like that. It does happen but it won't go halfway into a 12" barrel, it'd prolly go 3" at most into a larger bore barrel. This is my guess...You don't need to be paranoid about this...

[X-Plosive]

Okay sorry guys but I am stumped.....There is no way the spring will fit in my barrel......Lets see. What I presume happened was that the bolt was got caught on the nubbin and that the spring had just been compressed. Maybe it didn't go in the barrel. There is no real way for me to know seeing how it happened nearly a month ago. As for all these comments that appear more like flames I hope you all burn This would explain the springy feel when I tried to pull the nubbin out but exactly was the spring able to stay so tightly on the bolt lip? It took a lot of pressure to get it to give. I had the body on and did not examine it closely. I would however like for someone with some knowledge to answer this post when they get some free time.

If you do not belive what Army and Xplosive said was true then please call Agd.

Major Damage

This also happened to Major Damage, except his was even worse than X-Plosive's. Regardless you will need a new barrel.

[RobAGD]

Ok you have a few different things there were brought up.

#1 - The bolt AND Main spring leaving the main body and lodging into a barrel

#2 - Nubbins rolling over into the barrel

They are very different things. and words apart in what causes them to happen.


A) You can not under any reasonable change get a main spring to enter a barrel. It just WONT fit. B) The only way the bolt can exit the main body it to come completely apart. 2 different things could happen. The Power Piston can some un-soldered in which the foamie land and the center of the bolt will leave the barrel. I have only heard of this on Bolts that tried to use a Delrin center. Next the entire engagement land would have to break off allowing the outer sleeve and piston to LEAVE the barrel.

So having the barrel and main spring enter and lodge in the barrel isn't likely to happen. So it's a non issue for Tom to deal with or answer your question. He isn't here for YOU to badger with stupid question on problems that don't exist.

B) Rolling nubbins. Nubbins BEND they are metal. They are harder than most barrel material and there for leave a dent in the nubbin area. The P nubbin roll over because they are too deep in the barrel and allow the bolt to catch the nubbin in an over square area and the nubbin wont ride up the bolt face, it just rolls into the barrel where its being forced. V nubbin only roll after they break.

The bolt/barrel fit is tight and with that added material the bolt will wedge into the barrel / breach area. A good whack and it will release. Take a small fine diamond file and smooth down any burrs and your barrel will be just dandy.

You sir need to get off you freaking high horse. IMHO you think entirely too much of yourself and your issues.

ok Daniel, here's what I can gather happened, and pleas take this with an open mind, don't make me waste my preverbal breath, and this will be long winded.

the bolt moved forward and cough the nubbin, bending it into the barrel a bit. on the next shot it caught and bent the nubbin all the way around and jammed the bolt half way(half the bolt that is) in the barrel, the spring is compressed against the retaining washer, but in not broken or in the barrel in any way shape or form. then you degas the marker so as to work on it. the marker is field striped and the valve comes out leaving the bolt and spring in the gun. form here there are a few things that can happen.

1: the bolt is knocked out the back of the gun with a long hard object, thus freeing the barrel as what happened with x-plosive.

2: the bolt is badly stuck, to the point where it can't be knocked out, and the barrel is forced out of the gun but it brakes the retaining washer out of the body (this would be difficult but possible, particularly if the weld holding the washer in place had become weak. this would make it appear that the washer had broken and caused the bolt to stick in the barrel.

now any damage to the inside of the barrel would be caused by the bent nubbin being dragged along the side of the breach by the bolt. the only problems this is likely to cause is with a sharp edge cutting your paint. a problem that is fixable with a small file.

firing the gun without a barrel could conceivably cause the weld on the retaining washer to weaken as the back of the barrel would help provide some support for it (providing the barrel does touch it (I don't know for sure I have a micro mag so I can't check, but anyone else here including you could check that.)

X-Plosive does this sound like what may have happned to you?

your best bet to prevent a broken nubbin damaging your barrel is to install "V" nubbins and be certain you do it right (but even then it could still happen) or when you can get some the new plastic nubbins. hey you said AGD wasn't doing anything to help with this problem? that's what the plastic nubbins are going to prevent. with the wire nubbins if it bent in the bolt could jam on it, and they are hard enough to gouge the barrel, but the plastic ones will probably just brake in to small pieces if this were to happen, and even if enough did survive to jam the bolt the barrel should be hard enough to not be damaged.

if you really want to go overboard then take out the bolt spring when the gun is not in use, as it does put some pressure on the retaining washer and it also shortens the useful life span of the bolt spring.

hope this helps you sleep better at night.

I finally see this post and it almost turned into a flame. First of all EVERYONE CALM DOWN! Second, I don't read every post in the tech forum every day. Third, as part of the forum rules you are not supposed to put vague titles to your posts. If you do, expect me to avoid them.

I only answer the tougher technical questions. Most people get a good answer from the members on a regular basis.

It sounds like your problem is the common "nubbin bent in the barrel". We now have plastic nubbins that will completely and totaly eliminate the problem, call tech support for some.

[Dubstar112]

Yeah... Thanks a bunch AGD

The new plastic nubbins are impossible to be adjusted incorrectly, and they work good with the warp..

[thlibo]

Hmm, having read all of this stuff, and frequented the newsgroups for the last few months, I have heard of this bolt problem, but in the end it always involved nubbins. In any case Daniel Morse, you are a moron who would rather whine and point fingers than solve the problem for real. Call Airgun, their phone number can be found at http://www.airgun.com

Stop being such a big baby.

[Hexis]

In every instance what you are reading about is simple bolt stick. It's usually casued by a broken nubbin. This has been fixed by the new plastic nubbins.

Think about it, if the back of the bolt broke off, how would the bolt back out slowly and be ready to fire again? The back is where the spring pushes against.

[X-Plosive]

This is not a big deal, it's fruity but nothing more than that. Drizit, I didn't break the weld on the retaining washer. My problem was simply caused by the nubbin catching the bolt. I just had to yank the barrel off. I have plastic nubbins and a delrin bolt so i don't think this will ever happen again.

[mongrel]

ok everybody
take your barrel out of your mag.
look at the end of the barrel that slides into the gun.
when the barrel is in the gun it is almost touching the washer that is welded into the mainbody for the spring to push on.
the only way the bolt could get stuck in the barrel is if the flange that the sear catches broke completely off.
it cannot happen the way these people said it did, because the washer would hit the end of the barrel and stop.
i think somebody is just trying to get a higher post count.
