Leupold QR 1 PC BASE TC/C

the mount allows me to remove my leupold scope and transport my g2 rifle set-up in a very small case. when i put it back on it seems to hold the zero well. i carry a deer caliber barrel, and a 22 lr barrel together and i can switch the scopes between the two, the zero on the 22lr is close enough for squirrels when you practice enough. just make sure you choose the right height scope rings, or you might have to use a hammer extension. i took a white tail in november with a 357 max barrel at 20 yards and it was spot on, i just had to squeeze my thumb under the 1.5-4 x 20 scope. this was with medium height rings, so do your home work. great product.
