純正メカボックスの軸受け破損に伴い購入しまいした。＜良かった点＞①いわゆるポン付けで快調に動きました。②ギアノイズも少なく、初速も規定内で安定しています。③トリガースプリングが少し固め？　フルオートガンとしては、こちらの方が好きです。④軸受けがボールベアリングではないけど、インナーの軸がフリーで回るのでスムーズです。＜気になる点＞①M４のアッパーレシーバーを収める時、セレクタープレートとカットオフレバーの間のスプリングが引っかかって外れてしまいます。セレクタープレートのバネ部分のガード（盛り上がっている部分）が浅いようです。②M4/M16の固定ストックだとリヤ配線が短いようで、フューズボックスが外まで出ません。あと5㎝長ければグッド！③メカボを閉じるビスがトルクスのT8ですね。せめてT10かヘキサゴンにしてほしいです。全体的には良かったと思います。
