The LaRue Tactical RAT™ Stock (LT800-BLK) is an adjustable buttstock engineered for AR-15 and M4 platform rifles, chassis setups, and compatible Australian platforms equipped with standard Mil-Spec carbine receiver extensions. Constructed from an impact-resistant, glass-filled polymer frame with CNC-machined internal metal components, it delivers positive lockup without requiring secondary external friction locks. The stock incorporates a proprietary two-stage trigger mechanism for rapid length of pull adjustments, internal compartments for small gear or cleaning tools, and integrated sling attachment points for active field and range use.

Key Features

• CNC-Machined 2-Stage Trigger Release: Operates an internal adjustment mechanism that allows rapid length of pull repositioning along the buffer tube.
• Snug Mil-Spec Fit: Engineered for secure, rattle-free lockup on standard Mil-Spec carbine receiver extensions without supplementary friction clamps.
• Internal Storage Compartment: Features a sliding, locking rear butt-plate designed to store sectional cleaning rods, brushes, spare parts, or batteries.
• Integrated Sling Attachment: Equipped with ambidextrous 1/4-inch quick-detach (QD) swivel sockets alongside 1-inch web sling slots.
• Durable Frame Construction: Built from all-weather, impact-resistant glass-filled polymer reinforced with CNC-machined internal metal hardware.

Who is the LaRue Tactical RAT Stock for?

• Tactical carbine shooters — Requires a compact AR-15 adjustable buttstock with an overall length of 6.990 in (~17.75 cm) to maintain maneuverability while utilising internal storage for spare parts or batteries.
• Practical rifle competitors — Benefits from an adjustable buttstock offering a stable 5.30 in (~13.46 cm) height profile and a CNC-machined two-stage trigger mechanism that enables rapid length of pull adjustments between stages.
• Duty and hunting rifle builders — Requires a glass-filled polymer buttstock measuring 6.990 in (~17.75 cm) in length that locks securely onto Mil-Spec buffer tubes without external friction levers across harsh field conditions.

Less suitable for: Firearm builds utilising commercial-spec buffer tubes or fixed A2-style rifle receiver extensions; these configurations require fixed rifle stocks or commercial-diameter adjustable stocks designed specifically for larger tube profiles.
