Hey guys, I've got a waffen werks 74 with a wood Bulgarian parts kit on it. I'd like to set this rifle up to shoot past 300 yards. I know that's "possible" on irons but I'd like something like an acog or red dot with something n the 3x to 6x range magnifier. Basically I want to b good at distance but b able to shoot with both eyes open up close. Not looking to shoot sub moa at 1000yds, just minute of man out to say 500yds, 600 max. Basically I'd like input on what optic and how to mount it. Maybe recommendations on a nice stock with cheek riser and bi-pod? Do tws dust cover rails lock up tight and retain zero like they say?
