Testing of a refurbished Umarex APX .177 air rifle. This is a starter level multi-pump pneumatic suitable for plinking and informal target shooting. The two examples of this rifle I own produced 5 fpe at the muzzle.

Filmed September 2015 This is the night vision infrared camera prototype (work in progress) I put together as an add-on to my day scope. It isn't pretty, but it gets the job done.
