I recentry bought an AR-15 in 223/5.56 with a 20" 1:7 barrel to use for mostly midrange (out to 600yds) and maaaaaybe a little 1000yd shooting at home. The primary user is my son (he wanted an AR over my recommendation of a bolt-gun, but I didn't argue too much about it, it was a good price). I happened to see a Cabelas Covenant 6-24×50mm FFP in the bargain cave for $130 ($299 normally) so I grabbed it for this project. Hard to pass on it for the price.
Anyway, according to the website it has 40 MoA of adjustment. Which leaves me 20 MoA up or down. From what I get from JBM ballistics, my loadings should shoot 600yds anywhere from 16 MoA to 19 MoA. Which initially seemed perfect for a set of 20 MoA rings to me, until I remember there's only 20 MoA each way... when zeroed at 100 (or maybe 200yds) for more practical shooting I will be close to maxed out (the sight offset helps save me about 2 MoA) the oposite way with almost 38 MoA of adjustment left for drop. The alternative is using standard rings and hold over. The reticle does have convenient windage markings and at least 36 MoA of drop marked. So is a set of 20 MoA rings worth it or just use hold over? A different scope with more adjustment would make a big difference, but it does have a lot of features we like a lot for a great price.
(Sorry if it's a ramble, not always easy for me to put this stuff into words haha)
