Advantage Arms Glock 20/21 Conversion Kit .22 LR 4.6" Barrel Range Bag

Quantity
Buy on Ammo Depot

The Advantage Arms Conversion Kit turns a Glock 20 or 21 pistol into a .22 LR platform, letting shooters train with the same frame, grip, and controls they already use. It fits Glock 20, 21, 20SF, and 21SF Gen 1-3 models and does not fit Gen 4. The 4.6-inch barrel and 10-round magazine support range sessions, and the adjustable sights and last-round lock-open feature keep the manual of arms familiar.

Installation takes about 30 seconds with no gunsmithing required, so the kit can be swapped in and out between range trips. A range bag is included for storage and transport, and the kit is backed by a 1-year factory direct warranty.
