so back in November, surefire had a sale. half off of muzzle devices. great. I bought 2 of them. 2 for the price of 1....awesome. December 14 I received an email saying my order has shipped and anything on backorder will be shipped at no additional cost once it becomes available. okay that's fine. time passed and I forgot about it. well I was cleaning up my inbox today and seen the email from surefire. realized I still have not received my other muzzle device...ALMOST 4 MONTHS LATER. wtf. I will be contacting surefire on Monday to see what's going on. has anyone ever had this type of experience with surefire?
