Recieved this firearm from my DIL she did not know what features I wanted so I ended up with the muzzel not being crowned and standard trigger ! Is it possible to buy the accutrigger somewhere ? I think I could live with the muzzle not being crowned as these guns are very accurate ! I hunt usually at 50 yards with rimfire and would like to attain 3/4 inch groupings on a bench rest ! T Y for any input you can provide. MDT
