I recently installed a quad rail on my SAR1,I equipped it with a Sight Mark reflex scope,after 100 rds or so,the scope no longer turns on.I'm wondering if the recoil kicked the crap outta the scope to the point of where it tapped.I am now in the market for a red dot,would like to keep it around $150.Should I install new red dot on quad rail or side mount as I have one laying around? Thanks in advance.
