An inventory of basic parts for keeping your AR running. Not something you change out during use...but things we neglect whilst cleaning. Such as??? I don't know...what is it we don't do when we break 'em down and clean the barrel and wipe everything down?
Next, since there are so many new AR users, maybe just how to use an AR might be a good thing. How to charge it, how to change a mag, how to open the thing up....be careful where you point that thing when you're doing all of that stuff.
Just surmising that ya'll are gonna be down the road from the house filming since the tac rifle class ends the day before. If ya'll do a take off on newbies, I've got 14, 17 & 19 year old young men in the house you might be able to use to film a basic how to. They can bring their own AR & ammo too....maybe an FAL or PS-90 for variety.
