This is Twinke Masta's M16A2 carbine Model 727, made by Acid Snake from combining various parts of Twinke Masta's M16A2, M4A1, and CAR-15, with some edits by me and SV BOY. The handguard has been cut in half and barrel has been shortened to be able to mount M203 grenade launcher, and to resemble the real Colt M727/M720 with 14-inch barrel as closely as possible. The pack includes three animations (IIopn's M4 from Black Mesa Animation Revamp, and Toadie's "M4 v2" and "Gothic Serpent"), 3 hands for each animation (standart SC, remappable SC, and OpFor hands), and custom sounds for each animation, as well as 3 texture options, PeeWees, grenade models from Half-Life Improvement Team: Content Upgrades pack, and new muzzleflash sprite. New firing sounds have also been made out of L4D2 M16A2 sound. Source files are also included, which includes the original M727 .smd, decompile of each animation, some unused animations and .smds, as well as original sounds and texture edits.
