Full AR-15 Stock & Buffer Tube Assembly in One Package
Instead of hunting for separate parts, this ATI Outdoors kit gives you everything you need for a complete stock assembly:
This makes it an ideal choice for new builds, lower receiver upgrades, or replacing worn-out OEM hardware.
TactLite GEN2 Six-Position M4-Style Stock – Adjustable and Lightweight
The TactLite GEN2 stock is engineered to provide a comfortable, configurable shoulder mount while keeping weight to a minimum:
Six-position adjustable stock for personalized length of pull
M4-style profile with slim, compact lines
Weighs only about 6.10 ounces, making it one of the lighter tactical stocks in its class BattleHawk Armory+1
Whether you’re wearing body armor, heavy clothing, or shooting from different positions, the quick-adjust design helps you find the perfect fit in seconds.
TracLOCK GEN2 System – Rock-Solid, No-Wobble Lockup
Cheap collapsible stocks can rattle and shift. ATI solves this with their TracLOCK GEN2 system:
Provides smooth, secure stock adjustments
Eliminates horizontal and vertical movement of the stock on the buffer tube Buds Gun Shop+1
Locks down firm with a single lever – no need for extra locking mechanisms
Designed to avoid interference with the charging handle and to eliminate snag points on gear Buds Gun Shop+1
The result is an adjustable stock that feels more like a solid fixed stock once locked—boosting confidence and consistency on every shot.
X Series Thin Butt-Pad – Comfortable, Non-Slip Shoulder Contact
At the rear, the TactLite GEN2 uses ATI’s X Series thin butt-pad:
Non-slip pad helps keep the rifle planted in your shoulder
Thin profile maintains a sleek, compact feel
Removable design allows you to upgrade to an X1 or X2 recoil-reducing pad for even less felt recoil and additional length of pull Buds Gun Shop+1
This makes the stock adaptable to your preference—run it thin for a short, close-quarters setup, or upgrade pads for more comfort and control.
6061-T6 Aluminum Mil-Spec Buffer Tube – Strong and Precise
The included buffer tube is built from military-grade 6061-T6 aluminum and finished in Type III hard anodize: BattleHawk Armory+1
Mil-spec diameter for maximum compatibility with mil-spec AR-15 stocks
Type III hard anodized for abrasion and corrosion resistance
Precisely machined for smooth stock adjustment and long-term durability
If you’ve ever dealt with out-of-spec tubes that bind or wobble, the ATI mil-spec tube is a welcome upgrade.
Sling-Ready: QD and Tactical Sling Attachment Points
This buttstock assembly is built for real-world use with modern sling setups:
Dual-sided QD attachment points allow quick-detach sling swivels on either side of the stock Ammunition Depot+1
Integrated slot for tactical sling attachment works with traditional web slings or two-point tactical slings Shooting Surplus+1
These options make it easy to configure the rifle for patrol, defensive, or competition use with your preferred sling style.
Weatherproof Construction for Harsh Conditions
From the buffer tube and castle nut to the stock body and butt pad, the entire package is:
Designed to be weatherproof for outdoor use in rain, snow, or humidity Shooting Surplus+1
Built to resist rust, corrosion, and environmental wear
Tough enough for duty rifles, truck guns, and hard-use training carbines
If your AR-15 sees real-world field time instead of sitting in a safe, this stock and tube combo is up to the task.
