Along with the factory SL8 parts, the basic parts required for a SL8 to G36 conversion are:

  • G36 rear section at least 3.5 inches long or TBT rear section
  • G36 buffer plate
  • G36 push pin
  • G36 lower
  • G36 Magwell
  • G36 bolt head
  • G36 stock (of your choice, there are several options)
  • G36 stock axle pin

This conversion also requires a firearm to be 922R compliant.. On this platform, 5 parts are required, 6 if you use a German muzzle device. The most popular compliance parts start with the G36 P-mag, which counts as three parts. Boltheads, triggers, sears, gas pistons, barrels, are all available as well. HKparts.net is the best source for G36 parts. However, there are some available on this site.

There are three basic G36 models: the G36C 8 inch barrel SBR tax stamp required, G36K 12.79 inch barrel SBR tax stamp required, G36E 18.3 inch barrel. The required barrel length for title 1 on the G36 platform is 16.5 inches to keep the overall length at 26 inches. While the conversion makes a great collectors piece, You can typically buy 2 of our US made TG36 variants for the cost of the SL8, parts and labor. In todays market parts are tough to find and over priced, Parts kits are generally well past their service life so you have to be careful buying a trade in kit, we have seen many kits with shot out barrels and lowers that are so worn its less expensie to buy a new one than it is to restore it.
