Starting a purpose driven build

[WickedWillis]

I would pick up a TR24 from Trijicon for the optic. The illuminated triangle is excellent and is light weight. You can find them fairly cheap now used. I typically see them for $600 used with a mount on armslist or tacswap. I would look into a 16 and put some sort of hybrid flash hider compensator like the SureFire WarComp.

My only concern is the TR24 in low light to no light.
