The Lonex 200 Round Mid-Cap M4 Magazine is a solid magazine offering from the ever-reliable company, Lonex. The magazine externally features a polymer shell that has a waffle design on the outside, and a 200 round track on the inside. Unlike some other magazines on the market that advertise a high capacity and have feeding issues, these Lonex Mid-caps are a perfect 200 round capacity, and feed very well in rifles the magazine fits in. Compatibility is generally with rifles that use the "classic" M4 magazine well cut, and will not fit in the HK416 platform. Specific rifle model fitment cannot be guaranteed  Specifications: Manufacturer: Lonex Model: Polymer M4 / M16 AEG Mid Capacity Magazine Magazine Capacity: 200 rds Color: Blue Package Includes: Magazine Features: - Polymer Construction - Waffle Pattern Design - 200rd Capacity
