Major Superbolt problem

[Russ]

just sand the front end of the bolt down 1/16-1/8 of an inch with a belt sander!!

HACK! Please don't do that. Shame on you, kilaueakid :)

I am having a similar problem to Dave's. My superbolt is not any longer than the previous bolt (foamie), but it will break balls like mad. This happens regardless of my ROF and frequently happens on the first shot. I have had this problem for two weekend in a row.

Is this that isolated?

Just got back from the field 15 minutes ago, my friend had the same problem.. but with the stock emag bolt! it protruded out into the breech area sometimes (more than normal), and he chopped a couple times.

When he gasses up his marker, the bolt won't stay back (gas down the barrel) until he reaches a certain input pressure.

The bolt being forward makes me think it's something sear or bolt spring related.. but the part about gassing up sounds like a powertube spacer problem.. what do you guys think?

i m havin similar troubles. and from what i ve read on other posts I think it is the power tube spacer. Some one said ( i dont remember who or which thread) to go to the next size smaller spacer.

[kilaueakid]

I know, I know...shame on me! Don't sand the front of the bolt! I was kidding. Did anyone try a different power tube spacer. Let's hear some feedback from the guys that were having problems.

[DrEvil]

i didnt change my spacer but it seems to have gone away. It ll stick every once and a while but I just take off the air and it frees up.

Russ,

I just saw this for the first time. Your sleeve might not be on all the way and it is possible that could slip through on the first batch. Go ahead and sand off the front of the bold and I will send you another sleeve no charge. Let's see if that fixes it.

did you for mean me to sand the bolt down? Well, I sent my gun in to Jon along with the superbolt and he will check it out and see whats up.

hmmm, and I also have a belt sander:)

ben_JD- Please call Jon at the AGD tech department for further assistance. I'm assuming the bolt sleeve isn't all the way on and you'll need to replace it or try sanding it down. Talk to Jon and see if he wants you to send in the gun and bolt or send you a replacement sleeve.

I just got my superbolt. I have the exact same problem. The bolt length is exactly the same as the regular extended nose bolt. But, for some reason, the superbolt will sit a bit higher up on the powertube. Balls will hang between the bolt and the barrel breach with the superbolt.

Anyone know how to make the bolt sit lower on the powertube? Seems to be some tolerance issues with some powertube/superbolt combos.

Suggestions are welcome. No I don't intend to sand the bolt. If it comes to that, I'd just return the bolt. The reduction in recoil is nice though.

Help!

I forgot to mention, that the delrin bolt sleave is fully on the metal base. No gap at all. Bolt length is exactly the same as regular bolt.

Maybe its this?

I'm not a mag genius or anything, but maybe the lip at the bottom of the bolt that the sear catches is not as wide as a standard bolt. This would mean that the bolt may be the same length but it pushes out of the powertube farther before the sear catches the bolt lip? Just a thought.

Checked that. The lip is the same. Take your regular bolt and have it sit on your powertube. Notice how it feels a bit springy sitting on the powertube? You can push it down on the powertube and it will move (with some resistance) toward the base of the bolt. This is what is different. The superbolt sits a bit higher.
