This gas powered M700 sniper rifle at Gunner Airsoft is based on Remington model 700 Police is simply re-stocked Remington model 700 VS and is a clone of either the Tanaka M700 or the KJ Works M700.  Since the magazines of the Tanaka and KJ Works versions are not interchangeable, we recommend that you get the Bell magazines for this since you may just waste money buying any M700 magazine coming from these two, they may not fit too.
