Oh boy, where to begin...
Started off as a STAG-15 RIS.
First went the outer barrel, replaced with a Madbull Noveske 14.5" and a DBoys MK16 flash hider (which looks good on every gun ever), and the front sight replaced with a VLTOR knock-off.
Next went the grip, I hate the finger shelf on AR-15 grips. Replaced with a UTG ergo-grip.
Then I got a Madbull PWS aluminum body, which was a pain to install. But it looks nice.
Accessories: Thermold mag, AFG.
The gun is still a work-in-progress, it's not suited to CQB (basically all I play anymore) so it's gathering dust. Pity.
