Airsoft Surgeon reinforced parts offer you spare replacement parts for your pistols made out of precision CNC machined aircraft grade Aluminium. Stock parts in many guns are designed for lower powered legal limits in Japan. Airsoft Surgeon tunes guns for full Top / Green / Propane gas pressure loads and even power upgraded power weapons so his custom reinforced parts are especially crafted for these reasons.
This particular part is not a replacement but rather an addition, an upgrade component. The original Tokyo Marui MEU design has a slide that sits on the rail and is held in place by a slide guide but the frame only supports this on the right side with nothing on the left. The lack of a left support can create wobble and instability. This little component installs on the the frame, just inside on the left side and creates a slide guide on the left side as well.
This additional guide ensure less wobble in the action, a more stable slide action cycle with a much narrower margin for sideways movement and rotation.
This product will fit Marui M1911, MEU and even Marui DT.45
