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.\u003c\/p\u003e\u003cp\u003eMachined 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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e .22 LR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Conversion Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Lower:\u003c\/strong\u003e Glock 20 \/ Glock 21 (Gen3)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 7075-T6 Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Matte Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Complete .22 LR upper assembly, 10-round magazine, range bag\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-in, no gunsmithing required\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Advantage Arms","offers":[{"title":"Default Title","offer_id":47943420313855,"sku":"AACLE20-21","price":271.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1239474.jpg?v=1766573085","url":"https:\/\/doublestackstore.com\/products\/adv-arms-conv-kit-for-le20-21-w-bag","provider":"Double Stack Store","version":"1.0","type":"link"}
