Moonlight is hosting atm, and I just went a bit crazy with the P90, M79 and a bit later with the Truvelo (replaced the M79). My Truvelo ran out of ammo so I had to switch to the P90. Now I was in a difficult situation, sitting on a small tower without the possibility of getting down alive, and just having the P90 and no wrench. The enemies knew where I am, and I basically had to return fire. So I tried it with the P90. I always thought the effective range for all SMG's in this pack is under 100m. But then I killed someone on around 240-250m. With less than one magazine. I think laying down and firing single rounds has a greater effect than I thought...
