Hello all,
Not sure if this is the right place for this...so the mods can move this if need be.

I'm getting ready to start my first build when my barrel shows up from gunshack. I know I need a barrel nut wrench, and a set of barrel blocks as well. Are there any other tools or accessories needed to make the job easier? Also I have a no go gauge for 243ai but the go guage won't be in stock till August. Is there any other place besides midway or any thing I can use in place of that for headspacing.
Thanks
