This morning was a very good morning at the range. With two 9mm - a very old Mod 92 (plain) Baretta & a fairly new Springfield XDs - and a Mod 29 Smith, I really chewed up the centers of two targets. I then went over to the rifle side - first time with my new Colt M4 to "zero" it in. Using two M16A2 zeroing targets I printed from the web, I put the first 6 rounds into the COM. I was really impressed with the Colt - right outa da box and zero zeroing with iron sights. But still considering a scope. No pics of the targets, so I could be "lying like a rug."
