The sale of these rifles has nothing to do with Heckler and Koch aside from the initial production of the G36 parts whenever that occurred. These are not HK-assembled and proof-tested G36 rifles (note the lack of Proof-Marks), but rather they are "parts guns", assembled from non-controlled parts kits that were easily acquired from numerous EU arms sellers and surplus companies. The only "controlled parts" in a G36 prior to September 2018 were the barrel and Bolt, the remainder was just "parts". So companies like Tactical Imports bought up non-controlled G36 parts kits, and in the past they sourced genuine HK Barrels and Bolts out of the US through HK Parts.net to complete the Non-Restricted "E" model G36 withn18.6" Barrel. The supply of parts kits is apparently plentiful, as 200 were purchased by at least one Canadian company prior to September last year when the EU export laws changed to become more restrictive. However, the supply of genuine HK Cold-Hammer-Forged G36E Barrels and Bolts has now dried up, necessitating the production of after-market parts such as Walther-Lothar button-rifled "match" Barrels and US-made Bolts. The reßult is these "mixmaster" G36 rifles built with parts from various sources and no HK pedigree aside from the production of most parts (along with B+T rails, Walther USA Barrels and GSG-9/HKParts.net Bolts). Hence the lower $7K price for rifles likely costing the importer/assembler around $4K landed complete.
