This is one of the three packs of Cliffton Vlodhammer's series of AR-15 animations - featuring M16A2 model from Firearms mod for Half-Life. As usual for CliffyV's packs, it is highly customisable, and features a large set of various hand models, Firearms sounds, sprites, and PeeWee and ammo models. Uploaded for archival puproses
I believe I remember first seeing this in Cleaner's Adventures and wondering where I could grab it.
Glad that's now been answered!
I think it was some other M16 model in Cleaner's Adventures. I believe it was Romka's, made out of HD pack M4 and modified to look like M16. I may have this model in my archives somewhere too
Ah, well. Consider me corrected! :)
It's been a while since I played CAd.
