Sumtoy mount on Remington 11-87 20 ga question

[GD1656]

I got a Sumtoy base for xmas. Could someone who has this setup measure from front of receiver to front of base on a rem 11-87 20 ga for me ? Thanks  Paul

You can put it any place you like.   We slide as far back as you can and sit on top with our rocking.   That will give you a larger field of view and let you look through the sight not at the sight. 

Should be 6-48 screws in it also.   

If you have any problems feel free to call us.
