M203 PTW upper with surefire M952V and G&P TA31NSN
my "light fighter" upper, 11.5 in PTW barrel with troy mid-evil flash hider, Madbull 11in troy VTAC rail, G&P QD tango down VG, TM short zoom 1-4x in a King arms SPR-E mount, enforce WML and a Solomonensis AN/PEQ-15 w/ IR illum/laser and vis laser
i took the inspiration for the light upper from this image of a US special forces operators rifle
lower is pretty boring; magpul enlarged trigger guard, G&P tango down rifle grip and repo CQB service receiver sling plate.
