I figured that played a part in it. You need to jump ship on the DOS nonsense. There are better clients out there.
What length rifle do you have the BC on? What's your experience been using it for entries and CQB?2) When teaching, I like to tailor my set up to what the student's will most likely be using, ie... never taught a CCW/civilian course in a drop rig, won't run a SWAT school in jeans & concealment gear. As the BC is designed by and for entry teams, I have it available for them to run & test to determine for themselves if it is a viable option.
I do keep some commonality between my training guns & work guns. Teaching gun is more of a T&E platform.
