Considering that I'm also an Army Guard NCO with the 86th Infantry Brigade Combat Team (Mountain) (I'm in the Support Battalion, and am moving around, but will soon be supporting 3/172 Infantry), I have a vested interest in the troops. (I never know when I might have to rely on THEIR ability.)
I have some loaner rifles that will be available, 10/22 Rugers that have been altered to add M16A1 type sights and make them more shooter friendly. We call them LTR's (Liberty Training Rifles), because they make an awesome substitute for the AR-15/M16/M4 series rifle as well as the M1/M1A/M14 series rifle. I also have a few other .22's and some centerfire stuff that can be made available to use.
Once we get full approval on Harvard, it will be posted. Watch for it to be named "Concord/Lexington, MA (Harvard)". A play on the location to get folks fired up on Patriot's Day.
