***They're here!!!!*** Even stronger, more gooderer!
Building an AR that takes Glock magazines? Well here is your ticket! Like the DB1015, this block can be used for two different platforms. The Glock small frame (9mm/40cal) flip it over and build or work on your Glock large frame (45acp/10mm)! Tightest lockup of any block out there without having to "fit" it to work! Stop ruining your mags!!
