Good job and I wish I would have found this before I installed my Faxon heavy 6.5 Grendel barrel in my Mk12 upper. I used a torch and hand issues getting them together. Yep, have a no bounce hammer and 1" wood dowl during the installation. I went 45 seconds and still had to tap from the muzzle end to fully seat.
