  1. I'm an old military guy, so I've always done the 25/300 zero. Hell, I have a stack of printed 25 meter military zero targets sitting in my closet. Only reason I changed that was because the range I shoot at now doesn't have a 25 yard rifle range. With this new scope I'm getting it's set up for a 100 yard zero with a BDC reticle. Probably what I'll do is just put it on paper at 50 (using the 200 yard aim point) then actually zero it at 100.

  2. Great points. I do a lot of long range shooting (800-1000yds) not only do you have to zero to particular bullet weight but particular brand of bullet or if you're reloading so much care has to be taken to match the ammo. Thanks for the video

  3. Wont like this comment. 2 mistakes. (1) Scope is mounted WAY too high above the bore. Closer to the bore the closer line of sight the less variance of bullet flight path. (2) I might be wrong, but it looks like you were using your magazine for a rest & if so thats gonna kick entire rig around when firing. Thoes STUPID high sights on the M16s never did make any sence & that seems to have carried over to civilian ARs. IT was stupid then & its even dumber now. Contrary to popular beleif bullets do NOT rise coming out of the bbl. (A lil spin drift @ extream ranges) but under 400 yds the bullets fly out STRAIGHT & drop. Compensating for drop is a lot easier than tall sight/scope alignment arc.

  4. Things to consider. Shoot every distance to verify. There are a lot of other things that go into your zero placement at multiple ranges and you should know for sure if you are going to be high or low at each distance. What is the length of barrel being used. What is the weight of the bullet? What is the twist rate of the barrel. All of this will change where the impacts are at different ranges.

  5. I know that different cartridges will have different POI, but I never thought to use my primary rounds for zeroing! DUH! Thanks for that! You have a new subscriber.

  6. Showing the comparison w/ 55/62/75-gr. rounds is very strong instructionally! As most shooters rely on visual reinforcement, that MPBR groupings comp is spot-on. Thx for your obvious efforts that were put into this video ~ KUDOS!!

  7. Regarding the 50-200 zero: does this mean the sight axis (straight) and the trajectory (parabolic) intersect at 50 and 200 yards for a typical 55 grain, 5.56x45mm NATO round traveling at nearly 1,000 yards per second? I guess I should get out my calculator and work this out. I'm just surprised this rule of thumb works for so many different AR-15 builds with their different height differences between bore axis and sight axis, not to mention different barrel lengths … Thanks. Cool videos.

  8. So I've got a bit of a problem. I zeroed my AR (20 inch PSA upper) at 25. My front post sits up so high that it not only pokes over the ears but there's a gap between the base of the post and the hole it screws into. Can I bring the front post down to a sane height and fix my zero by adjusting the rear sight elevation?
