Ryohin Buhin Aluminum Frame for M4/M16 Series Electric Guns (Unmarked) & Exterior Parts Set (Metal Receiver Upper/Lower)

[Compatible Airsoft Guns] ■ Compatible with standard electric guns, M4/M16 series. [Installation Difficulty] ★★☆☆☆ - ★★★☆☆ | Installation requires complete removal and transplantation of internal frame parts. The gearbox is compatible with Ver. 2, but depending on the manufacturer, adjustments such as grinding down interfering parts may be necessary. This is an aluminum metal frame "unmarked model" compatible with standard type electric guns (Tokyo Marui and overseas-made AEGs). The engraving around the magwell has been omitted, allowing you to add your own original engraving or markings! This is a luxurious conversion kit that includes frame parts such as upper and lower frames, charging handle, dummy bolt, port cover, bolt stop, and magazine catch! Compared to plastic frames, the rigidity and texture are significantly improved, making it effective not only for realistic customization but also for improving accuracy.
