If you change the Bolt length, you can get a Demon 150gr!
I installed it on my GPX Demon150GR by changing the length of Bolt.
The bolt that came with SSK product was M6 Cap Bolt 55mm Silver color, but I changed it to POSH Stainless cap bolt M6×45mm Black color. Demon150GR has few variations of parts, so if you can't find your favorite design or color, it might be a good idea to use it. If you can't find your favorite design or color, you can use it. It's a great idea to have the Bolt in Black for a more parenthesis look.
