This older photo of a Delta force guy has some interesting stuff going on in it gun wise.
First off we have the redi-mag. Then the ubiquitous vertical foregrip that looks like an A2 pistol grip with surefire light common for that era on Delta guns. Then the optics.
I *think that is an ARMS riser with same brand rings with a Leupold scope I don’t quite recognize with a PVS14 mounted to the rear of the scope. BUID is the Knights 300 meter version.
The Colt M4 is old enough to have the CAR15 stock and the older grey looking anodizing.
I don’t know who this guy is. A retired Delta Force guy shared this photo yesterday among photos of other Delta operators who are all now deceased. So I’m assuming this fella is as well. RIP.
