im new to airsoft: Cleaning advice.

[brandon toner]

Hello everyone, im just getting back into airsoft.

i bought a KWA M4 RIS about 3 years ago and haven't touched it for past two years.

should i disassemble and re lube everything before i start playing?

how often should i lube the gears and o rings if i play a couple times a month?

Should i replace all the o rings since i haven't played in so long?

Thanks everyone!
