Just got an Axis .223 this weeks, feeds 4 types of ammo I have tried flawlessly! Dang things feels like the bolt is on roller bearings and the trigger is just under #2 after a 10 minute modification. It will group 3 shots just touching with factory ammo, or slightly larger, and under 1/2 with 2 different handloads, both using match flat base bullets. I got this for bargain truck gun/lightweight callingand running and gunning rifle, ss, and put a dBurris 4x12 on it.
