Loctite 609 for AR15 Barrel to Receiver: Removal Question

[GSS]

Take a look at the JP Rifles video showing how to assemble/disassemble their shrink fit uppers. They hold the upper receiver in a vice, apply heat and use a 1" dowel and a mallet to drive the barrel out of the receiver. There is not much area to strike on the upper and you could easily damage it. Driving the barrel out with a dowel centers the force on the centerline of the barrel and prevents cocking.

This looks like the video you were referring to

Nice / Interesting

I would like to know the material in the soft jaws in the JP video. Apparently it is heat resistant.

Edit: Apparently they are JP vice blocks.

Edit2: The JP upper receiver vice blocks are made of anodized aluminum. You can apply heat to the barrel socket without hurting the vice blocks. Cost is $80.
