Easy to install, one-piece insert machined from solid aluminum bar stock rests on top of factory magazine follower to allow single shot loading of long cartridges with heavy varmint bullets. Prevents bullet or case damage caused by normal feeding from magazine. Perfect for precision target competition or varmint hunting. Fits Brownells 20- and 30-round magazines and similar USGI-type mags. No need to disassemble magazine to install because follower slides in from the top. Locks bolt open after the shot. Clear anodized to resist wear; silver color contrasts with plastic factory follower to give you instant visual recognition that the insert is installed.
SPECS: Aluminum, anodized, natural silver finish. Fits USGI-style metal magazines.
