Well MB12 Sniper with Scope & Bipod
Some MB series sniper rifles are being released by Well this year, and WGC Shop now have the MB12 version in stock. This is a complete set with bipod and scope which will cost you a good US$123.00. The buttsock is adjustable and you can easily mount the scope with the short flat rail at the bolt area. It weighs 3.280 kg with a length of 1,140mm.
You may need to upgrade this air-cocking rifle as it fires at 240-260fps out of the box, which for an airsoft sniper rifle could really be underwhelming. The question is which parts to get for upgrades. If this is compatible with VSR-10 parts, then you're in luck.
