The Greyman Complete Build Kit – Stealth includes the core external components you touch and use on every range trip:
15" Greyman M-LOK Handguard (free-float)
Greyman Oversized Ambidextrous Charging Handle
Greyman Forward Assist
Greyman Adjustable Billet Dust Cover
Greyman Oversized Trigger Guard
Greyman Ambidextrous Safety Selector
Greyman Magazine Release

This kit is designed as a top-to-bottom control and front-end upgrade, giving your rifle a unified Greyman look and feel.
Designed for the Gunfighter – Function First
Timber Creek built the Greyman series around real-world handling and durability:
The new charging handle uses smaller wings to stay more streamlined to the rifle, with rounded edges to prevent snagging on gear while still offering enhanced texture for positive grip.
The new handguard features the cross-hatch texture throughout, improving grip and control during manipulation, barricade work, or when your hands are wet or gloved.
Front QD sockets were removed, leaving a flat front profile that mounts great with cans, making it suppressor-friendly and less cluttered.
Every component in this kit is about smooth function, snag-free operation, and positive contact under stress.
Stealth Finish & Type III Hard Coat Durability
The Stealth colorway gives your AR-15 a modern, low-visibility look that pairs perfectly with black and earth-tone accessories:
Greyman components use Type III Hard Coat for superior wear and corrosion resistance.
The Stealth tone is a subdued, tactical shade designed to reduce visual signature while still standing out as a premium finish.
If you’re building a discreet, duty-style rifle or a sleek competition setup, the Stealth kit keeps everything visually consistent and tough enough for hard use.
Enhanced Controls – Ambidextrous, Oversized & Steel Where It Counts
The TCGKS kit upgrades the controls you rely on the most:
Oversized ambidextrous charging handle for easier, faster manipulation from either side.
Ambidextrous safety selector so both right- and left-handed shooters can run the gun efficiently.
Oversized trigger guard provides more room for gloved hands and a cleaner, more aggressive look.
Steel takedown pins and steel QD end plate give tighter lock-up and added durability compared to basic aluminum or soft parts.
These upgrades are ideal for defensive rifles, duty carbines, and high-round-count training builds where robust, predictable controls matter.
15" Free-Float M-LOK Handguard – Slim, Suppressor-Friendly, and Grippy
The included 15" M-LOK Greyman handguard is the visual and functional centerpiece of the kit:
Free-float design for improved accuracy and consistency.
Full-length M-LOK slots for mounting lights, grips, bipods, QD sling mounts, and other accessories.
Cross-hatch Greyman texture across the handguard for better control when driving the gun.
Flat front end (no front QD sockets) to play nicely with suppressors and large muzzle devices.
If you like modern, extended support-hand positions and plenty of mounting space, this handguard checks all the boxes.
Gas & Muzzle Components Included – Ready for Your Upper
Unlike basic cosmetic kits, the Greyman Complete Build Kit Stealth also includes essential front-end parts:
Low profile .750 gas block to pair with most AR-15 5.56/.223 barrels with .750 gas journal.
E muzzle brake (.223/5.56) to help reduce felt recoil and muzzle rise.
Buffer tube to complete the back end of your build when paired with your preferred stock (not included).
That makes TCGKS an excellent choice if you’re doing a full upper refresh and control upgrade at the same time.
AR-15 Compatibility & Ideal Use Cases
The Timber Creek Greyman Complete Build Kit TCGKS is designed to fit most mil-spec AR-15 rifle platforms in .223/5.56 with a .750 gas journal and standard upper/lower receiver dimensions. Always confirm compatibility with your specific barrel and receiver.
Ideal for:
New AR-15 builds where you want a matched, premium component set from day one
Upgrading a stock rifle into a more capable, ergonomic “fighting rifle”
Duty and defense carbines that benefit from improved controls and a robust front end
Competition and training rifles where grip texture, ambidextrous controls, and free-float accuracy are essential
If you’re tired of mixed-and-matched parts and want a cohesive, high-end upgrade kit, this Greyman package is built for you.
