Just got my new .22lr upper last night. It's an 18" with XL handguard and I'm very impressed with the quality. It is 8 ozs lighter than my 3 gun upper, but other than that, they feel very similiar. It should provide for some cheap practice.
I ran about 300 rds of Federal bulk through it this weekend without a single hiccup. These things are friggin sweet! I just got it sighted in at 50 using a front bipod, but I'm thinking it will easily hold an inch at 50yds. My only complaint is the shot timer won't pick it up (CE Pocket Pro). Is there a timer out there that consistantly picks up 22lr? I know putting a comp on a 22lr upper is a little silly, but I wonder if it would add enough noise for the timer to pick up shots?
CED7000 will pick up even a suppressed .22
BTW: I know a guy who sells them
