Thanks for all the info guys. I suggested to my Dad he wears his glasses a little more often! I knew it didnt sound right but I really wasnt sure. Went shooting and had a great (and safe) time. The Enfield was suprisingly accurate. Drew quite a bit of attention when that big puff of smoke drifted out into the range. Alot of guys put down their AR15s and varmint rifles to come over and check it out and try a shot. Thanks again!
