The G&P WOC is one of the core type of gas blowback rifles with full operating bolt action groups. Magpul PTS has gone from tactical upgrades to common Airsoft benchmark options / fashion upgrade. This model combines both; the full venerable operating system of the WOC with the full set of Magpul PTS furniture to give you a gas blowback MOE carbine.
Feeding from the 50 round gas PMAG (metal body), it achieves about 370 FPS out of the box with a reasonable rate of fire. Of course, once you start investing in aftermarket upgrades, the skies the limit. NPAS for adjustable power, burst trigger groups, tightbore inner barrels, harder or lighter bolt kits, the list goes on and on.
With a fixed front sight and MBUS rear, the top rail of the Magpul PTS body will take standard rail attach after market optics. The MOE front system will take Mapul PTS MOE accessories which includes the option of MOE mount rails for the attachment of standard rail attach accessories like flashlights, lasers and grenade launchers. The benefit of the MOE system is that you do not need the added bulk, weight and rust factor of metal rails unless you really need them; Magpul PTS offering basic accessories for direct attachment to MOE front systems.
This combination of parts was possible before, but considering this is a G&P gas blowback M4 with full set of Magpul PTS parts, metal body, gas PMAG and rear MBUS sight this is quite a bargain package for those looking to modify in this direction anyway.
