Fierce Firearms Chassis Kit — Black | Fits AR-15 Long-Action* | Model LACHSBL | UPC 853418803950 Upgrade your rifle with a foundation built for precision. The Fierce Firearms Chassis Kit in Black (LACHSBL) delivers the rigidity, adjustability, and modular mounting serious shooters demand—transforming your build into a repeatably accurate, bag-friendly, and accessory-ready platform. With expansive M-LOK® coverage, a tunable buttstock section, and a rock-solid bedding interface, this chassis helps you lock in natural eye alignment, control recoil movement, and shrink groups—from field hunts to long-range steel. Model/SKU: LACHSBL UPC: 853418803950 Finish/Color: Black (low-glare, abrasion-resistant) Fitment: AR-15 long-action* pattern (see important compatibility notes below) *“Long-action” here follows the manufacturer’s receiver/bolt-length standard. Traditional AR-15 receivers are typically “short” pattern; verify your upper/lower interface, cartridge COAL, bolt and magazine spec, buffer system, and mounting points before purchase. Why Choose the Fierce Chassis (Black) for Your Long-Action Build Rigid accuracy foundation: The monolithic chassis minimizes flex and bedding shift so your zero stays stable through heat, rough travel, and seasonal swings. Shooter-first ergonomics: Adjustable cheek riser and length of pull let you set a relaxed, repeatable head position for faster target acquisition and reduced parallax error. M-LOK® everywhere you need it: Add bipods, ARCA plates, barricade stops, QD sling cups, and internal/external weights exactly where performance demands—without excess bulk. Low-glare Black finish: Professional aesthetics with real-world durability against scuffs, rain, dust, and range abuse. Better balance & tracking: Flat, bag-friendly buttstock geometry and weight-tuning options promote straight recoil and quicker sight return for faster corrections. Future-proof modularity: Update optics, supports, and accessories over time without replacing your core chassis. Key Features at a Glance Platform: Manufacturer-defined AR-15 “long-action” receiver spec (verify your interface) Adjustability: Micro-adjust cheek height & length of pull (tool or tool-less varies by package—confirm contents) Forend: M-LOK® slots at multiple clock positions; ARCA compatibility via M-LOK® adapters Buttstock Section: Flat underside for consistent rear-bag tracking; integrated QD sling points (check inclusion) Grip Interface: Accepts standard AR-style pistol grips (choose your preferred angle/texture) Finish: Low-glare Black, abrasion-resistant coating Model: LACHSBL | UPC: 853418803950 In-the-box items may vary. Confirm included mounting hardware, spacers, QD cups, and any ARCA/weight-kit compatibility with your retailer. Real-World Performance Benefits Repeatable precision: Rigid bedding and a consistent action interface deliver predictable cold-bore impacts and tight vertical through strings. Natural eye alignment: Fine cheek/LOP adjustments reduce neck strain and parallax—vital for long days on glass. Positional stability: Forend and butt geometry integrate cleanly with barricades, tripods, and rear bags for PRS-style practice and field use. Weatherproof confidence: Non-warping chassis construction resists moisture and temperature shifts better than traditional stocks. Ideal Use Cases Predator & varmint hunting: Pair with a compact bipod and rear bag for steady, low-recoil strings across open country. Long-range/steel training: Build a forgiving positional rifle with tuned balance and repeatable ergonomics. General precision carbine: Combine with a quality barrel and optic for a versatile rig that handles near-to-far engagements. Compatibility & Fit Notes Receiver interface: Built for the manufacturer’s AR-15 “long-action” specification. Verify your upper/lower geometry, bolt face, magazine standard, and recoil/buffer system before purchase. Barrel & gas system clearance: Confirm barrel contour, gas-block size, and forend clearance if adding full-length ARCA or weight systems. Grips & accessories: Accepts most AR-style pistol grips and M-LOK® accessories. Magazine system: Ensure your cartridge and magazines match the chassis’ cut and latch geometry. Suggested Setup (Pro Tips) Optic: 3–15x or 4–16x with a zero stop and dependable tracking—mount low, then set cheek height to align your eye perfectly. Support: A cant/lock bipod, a small rear bag, and a low-profile barricade stop up front. Trigger: Quality single- or two-stage trigger to capitalize on the chassis’ stability advantage. Balance: Add M-LOK® weights or an ARCA plate to tune center of gravity for your positional style. Sling: Two-point QD sling for hike-in carry and quick loop-up shooting support. Installation (Quick Guide) Unload & clear your firearm. Separate upper/lower; remove existing stock/handguard/furniture as required. Seat & torque the receiver into the chassis per manufacturer specs; use thread prep where directed. Adjust cheek riser and LOP to match your optic height and posture; lock settings. Verify function: Magazine insertion/ejection, safety, trigger, and bolt travel. Zero & confirm: Re-check torque after the first range session and validate zero. New to chassis installs? A qualified armorer can ensure correct torque, thread prep, and mag fitment. Care & Maintenance Wipe down with a damp cloth; avoid harsh solvents on coated surfaces. Re-torque action screws and forend accessories seasonally or after travel. Inspect M-LOK® fasteners/QD points; use thread prep per accessory maker. Protect exposed fasteners with a light corrosion inhibitor in humid/salty environments.
