Questions & Answers 9
-
Is your AT3 16-inch 22lr complete upper compatible on a radical firearms lower receiver?
Daniel · Dec 11, 2025AT3 Support Team — Yes, the AT3™ 16″ .22LR Complete Assembled Upper is fully compatible with a Radical Firearms lower receiver. It's designed for any standard mil-spec AR-15 lower, and Radical Firearms uses mil-spec dimensions, so it drops right on with no fitment issues.
-
Will this take the CMMG conversion Kit magazines?
Ken · Nov 14, 2025AT3 Support Team — Thanks for reaching out No it will not
-
Which 22lr magazines do you recommend for your 22AR upper?
Mike Hakala · Nov 12, 2025AT3 Support Team — Thanks for reaching out Yes we recommend the blackdog magazines
-
With this BCG and a Black Dog Machine magazine, is there Last Round Bolt Hold Open function?
Scott L. · Nov 4, 2025AT3 Support Team — It does not inherently have a true Last Round Bolt Hold Open (LRBHO) function on its own because standard .22LR AR-15 uppers typically operate by blowback and do not engage the bolt hold open mechanism like centerfire AR-15s.
