Mr AR15 this sounds fantastic...
Whats a ballpark price?
If you can afford a ballpark, you can afford the kit.
I wonder if the user will be able to insert the Ruger mag into the dummy mag himself. I would like to get a hold-open mag or something.
I don't like those banana mags they have in the 22 calibre Thompson so I was glad you hear that they are making a straight dummy.
