This small, easy-to-use scope camera lets you record each of your shots with great image quality. The camera can be attached to any standard NATO/Picatinny rail that can be found on most guns. The Runcam 2 has a built-in battery, that will last you for 240 minutes with the highest resolution setup (1080P@60fps). Check out the Novritsch Video Creation Guide which teaches you how to make Airsoft gameplays like a professional and how to grow your audience. Compatible with micro SD cards up to 128GB. You can choose between these lenses: 3,6mm Lens – best for pistols & shotguns (CQB range) 25mm Lens – best for rifles & SMGs (Medium range) 40mm Lens – best for sniper rifles (Long range) note: the 40mm version doesn’t work with the NOVRITSCH scope and mount. It is too long. A better way is to mount it on the barrel.
