It would not hurt to ask them. I have never had an issue with them delivering the goods although there was a thread some time back where some were having issues with them.
i have a $65 reddot from ncstar on my walther p22 target that wouldnt stand up to the punishment of a mini14. it sucked then and sucks now. maybe i "broke it" with the .223 but it wont hold zero on a .22 !
I just bought one of their Mini Reflex "green" dots for 74.99+shipping. Solid little unit. Sort of mimics the Burris Fastfire/Doctor/Jpoint type sights.
Going to shoot it in a Ruger Rimfire Series match this weekend. We'll see how it does then.
