Product Features

Our Full Top End Kits include everything you need to convert a Mil Spec AR-15 type rifle into a 9mm carbine. Only the best products in the industry have been selected for these kits.  These top ends were designed and tested using a MIL SPEC lower receiver with a Hahn 9mm Magazine Adapter and a Standard Hammer. Due to differences between manufacturers, we cannot  guarantee  they  will  work  on every lower receiver. Also available as a Top End only. Top End Only models do not include bolt buffer, Magazine block, or Magazine.

The use of this topend on an AR Pistol is legal, but the use of this topend on any AR15 rifle/carbine will qualify the firearm as an SBR and the firearm needs to be registered as such.
