I have this front end on my gun: http://www.airsoftgi.com/product_info.php?cPath=30_305&products_id=5719 and AirsoftGI was kind enough to not include the mounting hardware for the rear sight. Does anyone know of any place where mounting hardware can be found in Canada. It is an A.R.M.S 40L replica sight i believe. It would also be helpful if someone could let me know where to find a sight that would fit behind the extended rail on the conversion kit, again preferably in Canada. Rear sight rail space: Thanks!
