Things I liked:Totally solid. Perfectly balanced. Rubber grips. SA/DA. Trigger is very good. Compact. Accurate out of the box. Things I would have changed:Spring on magazine a little hard to grab and retract to load. Hide CO2 knob. What others should know:CO2/ BB magazine have rubber bottom like the grips and snaps firmly in place. No wobble. Drops free nicely.
Things I liked:This is great!! Easy to install. It puts the top point high up ( on the barrel ) where you need it for balance. Shoulder pad is very comfortable for heavy rifles. Holds in place well, I never feel like it is going to slip off. It does not get in the way when breaking the barrel. There are no metal swivel studs sticking out to jab you or hit on your case. Once set it does not loosen at all. Things I would have changed:The length is OK for me on a Hatsan 135 but if you were to wear a big coat or be really heavy the strap may not be long enough. For me it's perfect, a little extra strap to spare. I'm 6 ft 190 lb's. On the other hand if there were too much strap it would annoy me. It's just right. What others should know:In the rear it catch on the raised cheek piece, make sure your rifle has some sort of raised area. Doesn't take much.
