I have the same light set-up. Already have the Dillon 550. Will have to think about it some more. Next up for me right now is a tactical shotgun.Nice setup! My light is the SureFire Mini Scout with Larue mount. As you can see, I went with the Sig collapsible stock. So, two stamps required. I bought my MPX as a pistol so, had to put something there.
Might as well apply for SBR stamp while you are at it. I am sure you know these things eat up a lot of ammo so might as well order that Dillon 550 or 750. :icon_neutral:
Gun lust never ends does it? My last can took a year. They say just file the papers and forget about it. The way I look at it, unless I croak, next year will certainly come. When it does, I can have a nice suppressor or, not.
Best of luck to you.
