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, main one from L4D2, and the optional one by Navaro.
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.
A replacement for Insurgency Weapons Pack M16A1 was planned, but it was not included due to time constraints. It may be released as a separate skin someday in the future.
As a trivia, the correct classification would be Colt Model 720 aka XM4: a prototype of M4 carbine, based on M16A2 with 3-round burst trigger. I used "Colt Model 727" name because this name is more familiar to HL fans for being the name of the assault rifle from Gearbox HD pack, and because late versions of M720 look identical to M727.
