So has anyone see the Ras12 ar10 upper that takes propriety 12 gauge shells that look like rifle rounds. The shotgun looks really cool but seems to expensive bc the upper is like 2,500. I dont like the new 12 gauge shells either. But i think if the new shells become popular(i doubt it) the regular shot shells should be called 12gaugeR for rimmed like 7.62x54R. The new shells are not rimmed like the regular shells every other shotgun is chambered for. Supposedly the new ammo will b widely available when released. The cost is just waaay to high for a shotgun. I think a person could buy two MKA 1919s for the same price and buy lots of ammo and mags for them for the same price as just the ras12 AR10 upper. I encourage yall to look this up bc it looks cool but to me its not worth the price and having a new type of ammo that may or may not b avalible.
