I have a Bushmaster Varminter that I'm going to  put a scope on. What is the "Ideal height" for the bore center of the scope? The scope is a 4-16X50 Millet TRS-1.

Thanks in Advance!!

Simply pick a set of mounts that gets the bell of the scope off the handguard. Don't go any higher than necessary, though. The stock doesn't give a very good cheek weld and lifting your head makes it worse.

Thats pretty much it.  Good direct post.

I'm tying to do the same thing.  I have the Nikon Coyote 4.5x14-40 and medium height rings.  It mounted alright with a little clearance to the hand guard but near impossible to look through.  Its got to be higher, at least for my cheek.  I have the high rings due in tomorrow and I'll see how that works.

1.4 inches

As above.  1.40 inches is the height of the AR/M16 iron sights, and using that same height for an optic will be comfortable for most shooters.  Mount makers make conventional ring mounts that put the centerline at 1.40 inches as do makers of cantalevered mounts like LaRue, or shorter mounts can be used with a riser. The common mistake is to mount the scope too low.

Optimium eye relief is hard to get with conventional individual rings as they restrict how far forward the scope can be mounted.  That's where the cantalevered mounts shine, as the scope can be mounted a couple of inches further forward than is possible with individual rings.

Yeah, mounting close to the bore is for traditional rifles, not ARs.  You need it to be up high for proper cheek weld and ergo.
