Ok, I have figured out how the "Standard Barrel" and "No Accessories". This will need the modification from above. What do you think of this?
='Small Ranged Weapons'!EO25&", "&IF('Small Ranged Weapons'!EO28="STANDARD BARREL","",'Small Ranged Weapons'!EO28&", ")&'Small Ranged Weapons'!EO31&", "&'Small Ranged Weapons'!EO34&IF(AND('Small Ranged Weapons'!EO37="NO ACCESSORIES",'Small Ranged Weapons'!EO40="NO ACCESSORIES"),"",", "&IF(AND(NOT('Small Ranged Weapons'!EO37="NO ACCESSORIES"),'Small Ranged Weapons'!EO40="NO ACCESSORIES"),'Small Ranged Weapons'!EO37,IF(AND('Small Ranged Weapons'!EO37="NO ACCESSORIES",NOT('Small Ranged Weapons'!EO40="NO ACCESSORIES")),'Small Ranged Weapons'!EO40,'Small Ranged Weapons'!EO37&", "&'Small Ranged Weapons'!EO40)))&'Small Ranged Weapons'!EN43
Granted, it no longer will show "NO ACCESSORIES" if none is picked, but to me that is redundant information. It now only lists what you have. This also treats what is listed in the "Corner Shot" as an accessory, If you don't have it, nothing about it shows.
I wouldn't be surprised if there was an better way to do this.
