Instructions/Measurements for Barrel Installation for M3-M3A1

[K Squared]

Does anyone out there have the instructions for installing an M3 Barrel into it's collar?

I have a Taylor Arms Reproduction that appears to have used a surplus barrel and collar. I have the tax stamp to SBR it.

Thanks

I bet GotUzi knows...... I just looked at mine and there is a split roll pin that secures the barrel in place. What I don't know is whether or not the barrels come with a pin recess that seats it in the correct position.

Rekraps,

You're right about the roll pin!

I just don't know how deep to set the barrel in the collar. It doesn't look like the replacement barrels have a pin recess or shoulder to stop them at the right spot.

I've ping'ed the barrel manufacturer but, no response yet.

Thanks
