Bore size of stock barrel

[MrDewtles]

I'm thinking of getting a Spyder to put a pump kit on. I'm just wondering what the stock barrel size is.

I should have mentioned. Spyder victor.

Sorry.

Pretty sure all stock Spyder barrels are going to be in the ~.689 range. Probably not small enough to prevent roll outs with any of the the paint I've seen in the last few years.

A lot of them are 689 or 695.
You are probably going to want something aftermarket with insert for sizing.

If you want the best stock Spyder barrel to use ,track down one of the old brass lined ones. They are usually .685-.688 and can be modded into Freak bored barrels at home with a little heat and a tubing cutter

^this. They are smaller bore for the time period. I have quite a few of them and I'm pretty sure the largest is .688.

With some gentle heating the brass lining will push out.

Doing the same thing.

HK Army makes a one piece 681 in spyder threads.
Better than that is a freak kit.

I made the stock barrel work with a bit of electrical tape
