I have a $30 Simmons scope on a .22, but there's not much of a chance I'd put one of those, or even a higher priced Simmons, on one of my deer rifles.
You get what you pay for.
Come on, Bob, you've got an expensive weapon and you put cheap-shit optics on it??
Try this instead: Buy the OKO reflect sight from Dillon Precision, $199
Buy the Scout mount from DPMS, $49.99 (I fucked up-before I knew DPMS had them for $50, I bought the Scout mount from Dillon for-grease the brown eye and get ready for it-$70)
I've had my Panther shorty fall over a couple of times and the zero on that OKO hasn't moved yet. I've got about 1K rounds through the gun also.
So, for about $170 (including shipping) I got a kick-ass sight on a nice rifle and it didn't break the bank. Looks great too.
