This is why I love Polarstar... Can stick it in a ton of weapons, easy to customize FPS and RPS.
Instant trigger response, pretty sweet results with the right hopup rubber.
Sure it probably doesn't compete with a PTW, but it's not always an M4 or MP5 which blows it away in my books!
By all means, I get why they only produce the M4 and MP5 based on their targeted marketing.
