I just recieved my GG&G Accucam kit for my EOTech holosite. For those of you who might need ot use use AR for serious use (in the sandbox, patrol carbine, zombie uprising), I would suggest this product. Mostly for those whose EOTechs might hinder the use of their iron sites in a true SHTF situation where the irons need to be used. I purchase a VLTOR CASV handguard and it wouldn't allow me to use the irons cowitnessed with the holosite. I ordered the Acucam thingy from the Rainier Arms website and now, if I need to ditch the EOTech, I can do so fast. Its a simple product that seems to 'mostly" be of quality. I say mostly because I would suggest using locktite on the big flat head screw that is the pivot of the works. but it secures tightly and releases eaily when you want it off.
