I'm about to place my order for an SS 3-9x42 and I just want to double check with you guys who know a bit more about set ups to see if everything is in order and will work.
Scope:
http://swfa.com/SWFA-SS-3-9x42-Tactical-Riflescope-P41044.aspx

and then the mount is:
http://swfa.com/Bobro-Precision-Optic-30mm-Mount-P47215.aspx

My only question left is, since this will be going on an AR/SPR style rifle with a Magpul PRS stock, which style mount will suit this build better? The standard mount or the extended? I will not be shooting nose-to-charging-handle on this build.

Edit: Forgot to ask if anyone knew the discount/rebate code for SWFA. Thanks.
