I’m not sure about shotgun attachments. Likely chokes. They’d probably work like in Battlefield 4. Better ADS accuracy, worse hipfire accuracy. Slugs may still be present also.
Anyways, the Model 97 BETTER have its slam-fire feature, or ELSE!
Also, the game needs the Auto-5 and Sjogren. Look DICE, semi-automatic shotgun that’s SWEDISH! ADD MEOW!!!
