## Questions & Answers

**Q: Does the scope actually tell range of what you are looking at?**
A: Sort of....  There are a pair of vertical curved lines between which, represents the hypothetical shoulder width of a man, or about 18".  So, indirectly you can estimate the sight picture, if the scope is sighted in at 50 yards (please check your instructions to verify this).  Not perfect, but it helps.

**Q: Will this fit on a Remington 770 30.06?**
A: It fits if you have ring mount.

**Q: Does it come with a pair of scope mounting ring?**
A: You will have to purchase the rings.  However, they often are supplied as low, medium, or high height to assure clearance above the iron sights.  I ordered medium height for my .22 WMR Mossberg Chuckster (bolt action).  This works very nicely.  At 200 yards the pattern was about 3 1/2" using sand bags.  With a tripod I believe that a 2" pattern could attained.  BTW, I am using subsonic .22 WMR because of availability.  The drop is about 42" at 200 yards.  I holler "incoming" when I shoot.

**Q: This work good on a 30-06 gamemaster?**
A: Yes, the rifle scope work good on a 30-06 gamemater. Please contact us at email: info@feyachi.com. We will try our best to resolve your problem.
