I had my SCAR out today for its first skirmish and I have to say the other players and myself were impressed with how it coped with the weather. We were playing in Dundee (the hill) with a fair cover of snow and with the temp possibly being as low as -5 celcius. Firing using co2 with a stock gun other than a RA-Tech NPAS.
One or two minor problems with the mags nothing that wasnt expected just trying to do quick changes of co2 and a little bit of leaking while setting up (two out of six mags) but this resolved itself having shot the the gas out.
Can't really comment on the accuracy over long range white bbs and snow (everyone was having a bit of trouble with their hops due to cold)
On the plus side the bolt cycled well on semi and even a bit of burst fire. full auto firing for the whole mag which we tried to see if it was possible, the result was that the mag froze a little making it more of a challenge to remove the cartridge once all the gas had ran out. The noise it makes well as you all know certainly draws attention and scares the opposition when you pop up from a hidden spot. I had mates on the opposite team who said they could hear it a fair distance away along with my team mates WA M4.
Considering the Stinger hop and some extra mags to make the best of the limited ammo capacity and for longer games.
