The EDgun Leshiy is an extremely flexible airgun. The caliber can be changed in less than a minute with a simple barrel swap between .177, .22, and .25. The regulator is fully adjustable, and then you have the ability to fine tune with micro hammer spring adjustments. With this flexibility, small size, and ultra quiet capabilities, the EDgun Leshiy is the PERFECT pest control and small game hunting airgun. Leshiy TV shows it in action using the ATN X Sight 4K Pro 3-14x scope. If you prefer, you can watch on YouTube directly.
