Designed for left-handed FX Impact shooters in .22 caliber, the 701 Air A.I.R. Mag combines a press-fit ball bearing with a constant-tension spring for reliable feeding. The carousel accepts pellets and slugs and holds one additional round compared with standard FX stock magazines. Eight magnets retain the clear face plate and four rear magnets provide a place to hold it during loading. Left-hand use requires the 701 Air conversion kit; the magazine is intended for FX Impact M3 or M4 rifles.
