Completing Mega Capsule

I have 17 mega capsule gun, 3 left for dsr-black snake 1 of them is ak-47 black snake. as i see on roulete there are only 3, and one of them is black snake. if i get 2 left and only rest 1 for dsr , but that one is the black snake. will i get it? or what will i receive if i buy another mega cap and only rest black snake in the roulete..

Same rule that applies to every Mega Capsule Season...

Once the Jackpot weapon has sold out (the AK47 Black Snake), you can no longer get the Bonus Weapon (the DSR-1 Black Snake).

The M67 Black Snake Grenade and the P93 Black Snake are NOT COUNTED (they are simply bonuses).
