G&P metal body install using a TM stock delta ring.

[HellRanger]

From what I understand, the TM delta ring is a tight fit on the G&P metal body.

What I would like to know from the guys that install those bodies & delta ring combo on a regular basis is, what is your technic to make it fit.

Lightly filling, sanding the threads a little, etc...

I tried installing it with a Boa, but it only made it 3/4 of the way... Now the fun will be to remove it.

I will measure both a TM stock chamber block and G&P chamber block tonight to see the difference.

Edit: Solution was simple, the coating on the chamber block is just simply too thick. Dremell is your friend using a medium brush and not applying too much pressure.
