Trijicon 4x32 flip cap - Trijicon ACOG 4x32 Flip Cap Set (Requires TA91 killFLASH)

I think that these are made in the most simplistic way.that they could so you would have to buy the killflash. In all my years involved in small arms, including a small stint in the military from 1971-2000 I can't believe trijicon hasn't perfected a built in lens cap for the civilian people. I can understand why when deployed these cheap knock offs are not issued to the 11b or 0311 forces. They are not worth the monies, hard if not impossible to force over scope ends. Not.durable in severe heat or cold. Come on guys you make a heckler of a tube, lets.bring all accessories up to trijicon statue quo.
