Hi Mate, iv got a 177 tracker atm (on loan from a friend) with a 'AGS' scope & i dont think its 2 bad at all! i havn't had much chance 2 get it out & use it at a propper distance tho, only been plinking in the garden but seems 2 do the job pretty well. The only downside i would say is the noisy side arm cocking mech... i could see that spooking targets before u get them in ur sights!
