Where I play:
Terrain: Mountainous (Little valley with some woods and a strean, it's fairly devoid of trees.)
Teams: 3 Vs 3
Guns:
A. Rifles/Shotguns
1. AEGS:
ECHO 1 G36C, I use this in serious matches.
2. Springers:
No-Brand M2000 Shotgun (OK, but Hop-Up sucks.)
Cybergun Spring FA-MAS (Broken Spring)
No-Brand M4 (Didn't ever work, and stock broke COMPLETELY OFF in a week.)
B. SMGs/Pistols
1. Electric:
No-Brand P99, craptastic hopup and low rate of fire.
2. Springers:
Unmarked Brand UZI: Surprisingly good for a no-brand Chinese pistol.
KWC Tanfoglio Witness: Great.
