Last year I updated my PTW CQBR to look like a MK18 Mod 1 and this year I’m going to upgrade my Systema M4A1 into a SOPMOD block 2. 🙂

I picked up a used black Madbull M4A1 RIS II for $85 and it comes with all the mounting hardware despite only the rail being pictured. On the way are new BUIS and a Madbull Daniel Defense gas block too, heh maybe then I’ll be more inclined to use the M4. Maggie just rolled her eyes when I told her the M4 will look like the MK18 Mod 1, just longer. It’s going to be a fun project and I can’t wait to get everything I need to finish it off.
