What upper receivers are you guys using to get a good thermal fit?

I have two lapping tools. One from Brownells and one Wheeler.What brand is your lapping tool ?
I memory serves me... the Brownell's lapping tool fit my BCM uppers.... The PTG's would not fit the BCM's
That said... All my SOLGW stripped uppers are thermal fit... however they are all a few years old production.
The SOLGW uppers all have a snugger fit on ( between the upper and lower ) on various brand lowers.
From very snug on a BCM lower, ( have to slap it apart ) to much better on a PSA lower.
My Brownells tool is 15 years old. This particular upper was way too tight. It's not a big deal. I just prefer to go with something else for now. Having problems with two out of three was just too much.
