First Factory Tokyo Marui M4A1 MWS Lightweight Bolt Carrier End - Black

This lightweight polymer bolt carrier end is compatible with Tokyo Marui M4 MWS and TM MWS spec GBB Airsoft rifle series. It's made using strong, abrasion-resistant, and self-lubricating POM polymer resin, contributing to improved blowback speed and gas efficiency. In addition, three small POM polymer resin rollers significantly reduce drag and resistance when the bolt carrier comes into contact with the buffer tube, resulting in a more stable cyclic action. Both the body and roller are machined to a high-degree of precision. It is a simple drop-in installation and does not require modifications to ensure proper fitment.
