With a little bit of ridiculousness thrown in, Strike Industries put a SureFire 60rd magazine on to this SBR. They should have gone for gold and put a drum or 100rd SureFire mag on it. Oh and they added a DI Optical DCL-120 optic onto it. If its good enough for a 50 cal machine gun, it should be good enough for this. They need a Hellfighter on it now. Just to round out the entire package of over compensating.
