Diemaco SA 15.7 barrel disassembly: anyone done it?

Your build looks awesome man. Love the Geissele M-LOK rail you installed and the V7 parts (I have some myself). And you're going to love the SSA trigger.

As for the castle nut...Not sure about loctite but try heating it up first with a heat gun or something. Use the spanner wrench to remove it as that is an older style castle nut. Also, if you haven't already, tap back the staking that Colt Canada put on before you start but as you said before these usually come off even when staked.

Cheers and good luck!
