GRADE B STOCK
These have a slight manufactuing flaw where the upper and lower parts of the sector gear aren't precisely aligned (this can also happen with some of the higher-end gears).  The gears are still perfectly usable.

Designed for the TM recoil / NGRS AEG's only, these are essentially an upgraded version of the original ZCI gears released 10 years ago.  These new gears have a hardened CNC machined sector gear.

*** Please note, will not work in standard AEG's, these are for TM NGRS only
