Phaseline - Weapon Core

The Colt M4A1 URG-I (Upper Receiver Group - Improved) as a fully modular rifle. Every part is its own inventory item you can swap in the field.

PARTS
- Daniel Defense 11.5 in and 14.5 in barrels (muzzle velocity follows barrel length)
- Geissele MK16 10.5 in and 13.5 in handguards (Black, Camo, FDE) with tactical wraps
- M4A1 upper and lower receivers (Black, Camo), Magpul CTR stock, Magpul MIAD A2 grip
- Geissele Airborne charging handle (Black, FDE)
- BCMGUNFIGHTER vertical grip (Black, FDE, Green) and BCM KAG angled grip (Black, FDE)
- SureFire SOCOM 3-prong flash hider and SureFire SOCOM556-RC2 suppressor (Black, Tan) that mounts over it
- EOTech EXPS3 on a Unity FAST mount (Black, FDE)
- Magpul PMAG 30 GEN M3 magazines (Black, Camo, Tan) with M855 Ball, M193 FMJ and M995 AP

MAGAZINES
The rifle has a standard STANAG 5.56 magazine well: it takes vanilla M16/M4 magazines, the other Phaseline rifles' magazines and other mods' STANAG magazines, and its own magazines fit any STANAG rifle. Every magazine seats in the well the same way.

OPTICS
The top rail takes any 1913 rail optic, seated on the rail. A dedicated canted slot behind it takes 45 degree canted red dots (Phaseline - Optics); switching sights rolls the rifle onto the canted dot.

LASERS AND LIGHTS (OPTIONAL)
With Phaseline - Weapon Effects loaded, the handguards take its rail lasers and lights, M-LOK rail adapters and MK16 light kits. Weapon Effects is not a dependency: without it these slots simply stay empty.

ARSENAL
The rifle and every part are in the US arsenal under "Phaseline | M4A1 URGI".

Dependencies: Phaseline - Weapon Core.
Optional companions: Phaseline - Optics, Phaseline - Weapon Effects.
License: Phaseline R&D Group Mod License v1.0 (license.txt in the mod). Dependent mods, reskins and prefab/config edits through a proper dependency with visible credit are allowed; reuploads, repacks, extraction and monetization are not.
