I went ahead and used the BEV block and inspected the barrel extension afterwards and all looks normal. No marks of any sort on either part.
I’d actually already ordered the KAC rod but just thought to give the BEV block a try and I’m glad I did, I can save the 80 and put them towards a a couple boxes of ammo ! lol
KAC must have stock in the parent company of Rockset cause there was a TON of rockset on the threads, more than I’ve ever seen when removing a muzzle device.
