Advantage Arms Conversion Kit for LE20-21 – .22 LR Glock Conversion with Range Bag

The Advantage Arms conversion kit transforms your Glock 20 or 21 (.45 ACP / 10mm) into a .22 LR trainer without modifying the host pistol. This drop-in upper assembly allows shooters to practice fundamentals and increase trigger time at a fraction of centerfire ammunition costs. The LE (Law Enforcement) designation indicates compatibility with Gen3 Glock 20 and 21 frames.

Machined from 7075-T6 aluminum with a matte black finish, the conversion kit includes a complete .22 LR upper assembly, 10-round magazine, and a protective range bag for storage and transport. Installation requires no gunsmithing—simply remove your factory slide and drop the conversion upper onto your existing frame. Magazine springs may require a break-in period for reliable feeding. Always ensure your firearm is unloaded before installation or removal.
