G&P Airsoft TA31 ACOG Type 4x32 Scope
G&P's airsoft version of the ACOG is the nicest I have seen, with very good optical quality and a realistic reticule. Perfectly suited to outdoor/woodland skirmishing, will fit any airsoft rifle with a 20mm rail. Also the mount can be removed to alow fitting to a M4/M16 carry handle for that SWAT look.
Fiber optic on the top is a dummy replica - there is no illumination.
