Hey guys, was not sure where to post this so I figured this might be the right place. I have an old school Bob Long Millennium (very similar to the old Spyders) that needs a ball detent. The video here (http://www.youtube.com/watch?v=p68ZkFKXOuw) shows what kind of ball detent it is. Since parts for this gun are pretty impossible to find, will this detent work?

Looks like a cocker detent which can be found here along with some upgraded iterations:

Also, ANS has the CP detents cheaper.

As far as if that particular detent will work I can't say for sure but it looks like it should. At 5 bucks it wouldn't matter much if it didn't fit.

Awesome thank you! Defnitely will try out one of the detents from that site, they look pretty good. As for other upgrades, my Millennium is a very simple version (no expansion chamber, and no field strippable bolt) would an autococker chamber/bolt work? I was looking into these chambers here.. http://www.paintball-online.com/expa...ambers-0Z.aspx

I know the gun is ancient, but its the only one I've kept over the years. I'd like to do some minor mods to it. If you'd like to see pictures of it I can take a few.

I don't know much about Millennium bolts but from what I understand it can use almost any Spyder part (or at least those from that era) so it would likely use Spyder bolts as well. Spyder bolts are getting cheaper now. The barrel is Spyder-threaded and as you pointed out the blowback design is very similar to one.

Expansion chambers and gas-through chambers, and regulators for that matter, tend to be universal and most use the same threading. The ones which you linked should work nicely in your millennium.

Speaking of, I would love to see pics. Also I'm confused about the "not field strippable" part, does it just use an allen key instead of a pull pin on the back of the body?

[MarkusFATA]

No allen key as far as I could tell. I have not had this gun apart in a while and I plan on lubing it up soon but I'm completely lost on how to remove this bolt. Anyway here are a few pics, sorry for the horrible quality my good camera was dead so I had to use my phone.

Looks like there is a hex screw on each side of the bottom tube which holds the back plug and velocity knob on. The bolt is going to be connected to the striker in the bottom tube with a pin. Remove the screw(s) and the whole internal assembly minus the valve should slide out with the bolt.

To get everything back in the frame needs to be off as well, otherwise the sear will cut the striker o-ring. The marker is gorgeous!

Thank you! I will try to disassemble it this week. I did notice that my airline goes straight into the body of the gun, would this make it impossible for me to throw an expansion chamber on this gun? If not, I'm going to go ahead and get the Bob Long cyclone vacuum chamber.

An expansion chamber can be added but it wont screw directly into the marker. You will need an extra part called a vertical adapter which is like this:

The screw in the middle threads into the body and an oring around it seals it off.

The Cyclone vac chambers are for markers with a "front block" style vertical adapter while yours has a threaded adapter. The bad news is that the parts are not interchangeable but the good news is that the threaded adapters are cheaper. Once you get the VA you can attach any standard-threaded expansion chamber, or better yet a regulator, to the marker.

Ohhh a regulator would be nice. Just got paid so I'm gonna try to start ordering some of the parts. Still have not had the chance to disassemble the marker, gonna try to start tomorrow night.
