I' ve used the low line Bushnells many times in my life with complete satisfaction.

I once was carring a .270 slung over my shoulder and I slipped walking down hill in the snow. I hit the eyepiece of the " cheap" Bushnell on a rock and damaged the eyepiece and it let oxygen into the scope and it fogged up.

I returned the scope to Bushnell and they repaired it " FREE" and returned it to me in less than 10 days.

I' ve even used one on a .375 Mag with no trouble.
