Tang of Jag Precision gives us a close look at what they've brough to use during Milsim West's Strike On The Steppes event which took place last 22-24 May... "The gear and rifles used for an event are key in the mission success. Here we have a video of what Tang is using that are BFA’s (Blank Firing Adaptors) and AEG(Airsoft Electric Guns). He has made the Airsoft version with MadBull rails to match the firearms for this event. Using the Daniel Defense rail kits to complete the current MK18 rifle kit you can accomplish that with the Madbull Airsoft licensed rails on your VFC rifle as he has done."
