Since I always hear that "Springers don't work with Bi-pods" I decided to try the NP2 with Bi-Pods.
Using the bipods from a Black Ops here's what I got.
Now the target shows groups from both no Bi-pod and with Bi-pods.
Except I was shooting a pellet I don't normally shoot? I'd say the NP2 works nicely with the Bi-pods.
