I'm wanting to install a Kidd barrel into my stock receiver. I like the idea of heating the receiver up to 250 degrees to help install the barrel. I do this all the time with bearings and it really makes installation easy and quick. My concern is a possibility of blistering the paint? My receiver is one of the silver ones that appears to be a clear coat over bare metal. It would really suck to screw up the paint. BTW, the barrel will be in the fridge overnight.
