Hi bonker. I had one for a years. I shot about 1000rds througt it. I liked it very much but fit and finish was not up to what i like. So i sold it. It is suggested only to shoot subsinic ammo through it. Some complaints of sear and bolt handle breackage when shooting hi and hyper vel ammo. I was shooting Winchester 40gr sub hp without a problem. Accuracy is good also is weight and balance. For my part, when it's time i will go with CZ 512. Chers
