Things I liked:This is probably the best air rifle I ever bought. Extremely light, and extremely accurate! I fitted it with an Anschütz diopter and 2.8mm glass aperture insert, and made it into a training weapon for 10m match practise, with which I score similar results as with the club's Feinwerkbau 300. And that for a price of less than $100! This gun never ceases to provide a broad grin on my face every time I hold it in my hands! Things I would have changed:The rear sight notch blade has to be unscrewed for adjusting windage. It would have been nice if it had a knob for that to do. What others should know:Give it a lube tune before firing your first shot. The preservation lubricants Baikal uses have a tendency of being a bit dried up. Other than that, there's just one thing any airgunner should know: BUY IT!!! Accuracy and fun guaranteed for life!
