The 701 Air A.I.R. Mag for FX Impact is designed for left-handed shooters in .177 caliber. Its carousel uses a press-fit ball bearing and constant-tension spring for smooth, consistent feeding. Precision-cut grooves accept pellets and slugs, the design adds one round over standard FX stock magazines, and magnetic retention secures the clear face plate. Left-hand use requires the 701 Air conversion kit; the magazine is intended for FX Impact M3 or M4 rifles.
