the handle came off the toggle on mine,the only problem i had,glued itback on no problem. the rear site is a little clunky,not so clunky i would spend big bucks to replace it though. i cut a tape measure up and glued the pieces to the sight,which helped a lot. of course,the reason the sight is clunky,is these things were meant to take a lot of abuse. the take down pin for the toggle system,which is simpler than the anschutz,forms a stop for whatever sight you put on it,so the zero holds in my experience. very good adjustable trigger,along with the adjustable buttstock also.lots of accesories come with it. the biathlon loads that the russians use are not anymore accurate neccesarily than federal premium,but supposedly they are primed to fire in extreme cold.you can probably shoot reduced loads,but i reccomend running a patch thru every 15 to 25 rounds,or any time you think it got stuck in the barrel.big safety lever so easy to use with gloves.be sure to open the muzzle cover when using a scope.[no,i have not shot thru it,the air pressure may open it anyway,i don't want to find out.] obviously i like this rifle.very accurate.i would like to have some magazines that hold more than the regulation for competion 5. there are some 10 rds,but,for some reason are high and fairly rare,but i have'nt looked for any lately.i would also like to stain the stock,but i am in no hurry. i reccomend it,don't think you can go wrong.
