It's not tactical gear this time for the The Gear Locker, it's an airsoft gas blowback rifle... " The PTS Mega Arms MKM-AR15 is based off of your standard M4/AR Platform and operates using Green Gas instead of NiCad or Lipo style batteries. By using gas, the shooter gets the realistic recoil sensation as they pull the skeletonized trigger for each shot in 'semi', or flip the selector switch to 'auto' and feel the butt pad on the stock against your shoulder. When the last BB exits the magazine, the bolt on the MKM-AR15 locks back and you must insert a fresh magazine and hit your bolt release to allow it to shoot again.  The MKM-AR15 also has a functional forward assist and charging handle that, when engaged, opens to allow you to adjust the hop-up unit to fine tune your shots."
