I own one and used it without hardly any break in for hunting last year. We went all week and I didn't clean it because I wanted to know what it could do. We limited out every day, lots of shots, it did finally start to malfunction. Took me 5 minutes to open it up, wipe it with my tshirt put it back together and it worked just fine, no oil or anything. Russian knows how to make guns that are built tough, built to last, and RELIABLE, they don't care about prettiness as much but I find the gun actually looks quite nice. I just got a hold of some Carlsons chokes so I will try those out when the snow goes away. I did pattern several different brands of ammo through the factory chokes and actually find the cheaper federal steel shells to pattern pretty reasonably which works out very nicely at $20 for a box of 3.5". It will take some time before you can put the cheapest target load in and get it to cycle but it will happen. You CANNOT get a better performing and reliable gun for the money. I did a lot of reading before I bought this and there are countless stories I came across of this gun outperforming guns 2 or 3 times its price when out in the field hunting.
