just for fun a little bit of physics :

a normal .50 cal bullet can weight up to 50g

this weapon weighs 9kg

with the formula U = (m1*v1 + m2*v2) / (m1 + m2)    (U = recoil speed, m1 = bullet weight = 0.05 kg, v1 = bullet speed = 100,000 m/s, m2 = weapon weight = 9 kg, v2 = speed of the weapon = 0 m/s)

we can get the recoil speed.

(0.05*100,000) / (9.05) = 552 m/s

552 meter per second recoil O.o dafuq NK?
