Thanks WorldExclusive and others for the tip on the M16. For some reason, I never used the gun (other than first few ranks as Assault) and never realized its power. For some reason I had been running L85A1 which seems to have been nerfed a bit in the CQ patch.
M16A3 + RDS + Foregrip + Heavy barrel = raping people's faces at close and mid range, very accurate gun.
What are people running for engy and support? I've been trying the M27 IAR for the first time on CQ because of the faster firing rate, but keep coming back to my trusty PKP (RDS + foregip + heavy). Engy I don't know what I like, been using SG553, PP19 and shotguns.. DAO12 feels weak now (buckshot).
I use the M4 mostly for the engineer. Works reasonably well for everything. The 553 is also nice but I like the M4 a bit better. For support it kinda depends. The MG36 is pretty good all around. Kinda an "assault rifle replacement". The PKP is good for run and gun at close range, slow but very powerful.
