Armalite's 1 piece scope mount is pretty decent, for mounting a scope to an AR15 flattop it's about perfect.
The only exception, I find that it doesn't allow enough room for forward mounting scopes with REALLY long eye relief. That is part of the reason I put an adjustable butt plate on my rifle, to get additional stock length for a proper cheek weld behind my 6.5-20 Leupold Long Range. But I'm also a tall wookie like creature, it helps to have a longer stock as it just fits the rifle better to me.
Was out in McKittrick today, got in some GOOD shooting while putting my mil-dot scope to use.... ranged the target for 500 yards and shot some groups, after it was all said and done my friend whips out his GPS unit and marks the waypoint of the shooting position and the target position. Results came in as .28 miles! That's 495 yards! Even if the silly thing was rounding up to .28 miles from something like .275-.279 it's still a very close range stimation as .27 miles is 475 yards.
Just need to work on my load, was trying a new load today and it's not quite flat enough, I'd guess muzzle velocity for the 190grn SMK is right around 2750-2800 as it's only a midrange starting load. Gonna push the charge weight up and see if I can get it closer to the 2900-2950 range. The load I shot today was about 1.5MOA lower at 500 yards than a previous load I had tried.
Group size was just over 7 inches in extreme spread but all shots landed on an 8x14 inch piece of legal paper that I was using for a target and as a known size object for purposes of ranging.
I LOVE THE MIL-DOT MASTER!
El_Rojo, I'll be ready to go shooting again in a week or so. Maybe we can head out yonder and put some rounds down range, you can see if you like my JP Enterprises single stage trigger on my accurized AR15. Plus I want to put my accurized AR on paper at 500, I haven't yet put it on paper at any distance beyond 100 yards.
