Trijicon acog 5.5x50 red chevron bac reticle in .308 - Trijicon ACOG 5.5x50 Red Chevron BAC Reticle Rifle Scope

Its an ACOG what more than that do you need to know!?!?! Fantastic glass / clarity at all distances after its zero'd no adjustments nec. no diopter, no focus, no ranging the reticle does its job and built like a tank. It does have the minor annoyance of all acog's when doing the first zero in you must adjust then knuckle Tap it firmly to get the prisms to move, set, otherwise you move it no change, no change then big change Too Far! Hahaha but when its zero'd your set. This BDC is set for 20 inch barrel 168 gr. stated in booklet. I found on my PSA AR10, 18 SS, 1 in 10 right hand twist, barrel BDC likes and is Very good for Hornady 165 gr GMX out to about 600 yds., If I'm stretchin it out The Hornady SST 168 gr Poli tip boat tail with this mounted to my Ruger RPR precision 20 in barrel w/ZRO Delta muz brake in .308 is good from about the 3 hun Yds. stadia line to well beyond what my caffeine stabilized hands and old eyes can accurately judge LOL! (beyond 800 Yds.)
