HK SL8 t0 G36 Conversion


The SL8 to G36 conversion is a very exclusive and very unique firearm for collectors and HK enthusiasts. Although rare and hard to come by, we can help you obtain your dream G36 configuration. These guns are expensive and otherwise unattainable on the US civilian market!

The stock SL8 is not as versatile and not nearly as ergonomic. What you gain by doing the G36 conversion is not only looks and authenticity, but also a better feeling and better handling gun. The feel of the grip itself is much better and the folding stock option is a big improvement over the fixed, thumb hole SL8 stock. The factory SL8 stock is ok for bench shooting but we have noticed that it tends to irritate your hand after a bit of use… If you are in a state that does not allow the folding stock, it is still worth it just for the better feel of the G36 grip housing. These changes greatly improve the shoot-ability, ergonomics and feel of the SL8.

If you’ve always wanted a civilian semi-auto version of the G36, this is your best, most authentic option!

What to Expect

  • NO FOREIGN MATERIALS USED when welding or plastic fusing
  • NO FILLERS or putty, only melted nylon from the actual HK polymer
  • Bondo/body fillers, epoxy and other “quick fix” materials will crack, flake and compromise overall finish/durability. You will not find this in our work!
  • No waves! Smooth flat even surfaces ( Straighter than the factory since most mold waviness is removed during the process )
  • No pinholes in final finish
  • DuraCoat Firearms Finish w/ slight texturing, NO SPRAY PAINT!
  • Masked engravings to prevent texturing grit from obstructing markings
  • No rough edges or internal blemishing, bolt will slide perfectly, just like factory
  • No cracking, splitting or other weld failures, guaranteed ( 100% track record to date )
  • No rushed work/assembly line procedures or “unskilled help”
  • Hours of special attention to detail will be spent on YOUR project…
