CHEAP Compatible Nerf Rival 12 round Magazine KNOCK-OFF
A VERY CHEAP Nerf Rival 12-round magazine knock-off.
I recommend buying the black one so you could identify between offical Nerf magazines and cheap knock-offs.
Cheap knock-offs can have ignorable bad resolution in length due to hand measuring.
You are not going to buy a 6-round knock-off, are you?
