Airsoft Chay recently tested the APFG SIG MPX GBB and shared his impressions. This gas blowback (GBB) is based on the VFC system, featuring a realistic bolt mechanism. It is designed with a charging handle, a magazine release, and a bolt catcher that are accessible from both sides, enhancing its usability. The GBB is equipped with a 4.5-inch outer barrel that includes a tactical rail. It uses a 30-round 9mm style magazine and can achieve a velocity of 320 FPS using 0.2g 6mm BBs.
