Perazzi stock bolt size?

MX2000 made in 2000.
Is stock bolt a 6mm hex?
Would a ball-hex help.
I am going to buy the proper item.
Thanks, Ted

 

Go grab a 6mm ball-end T-handle hex wrench. The T-handle gives you way more leverage than a little L-key, which you'll appreciate if that bolt is stubborn. Plus, it's just easier to control when you're putting it back together so you don't cross-thread it.

 

Thanks for the advice, Ted
