Geissele released their 'never realeased to the public' super unicorn fbi 10" mk4 rail for Black Friday weekend only! $245 for black and $262 for the other color options! Just recently saw one go for $800 on eBay, awesome deal along with all their other rails and triggers being massively discounted!
