MDT HNT Carbon Fiber Fixed Buttstock - Black Carbon Fiber Finish, XTN Interface Standard, Foam-Filled Carbon Fiber Composite Shell, Adjustable Cheek Riser & Length of Pull, Dual QD Sling Attachment Points, Titanium Hardware - 114409BCF / 990482725440
Product Description
Lightening a backcountry hunting rifle or building an ultralight competition setup requires a buttstock engineered to eliminate rear-end mass without sacrificing structural rigidity, adjustability, or shot-to-shot consistency. Standard metal or solid polymer buttstocks add unnecessary weight that creates rearward bias, making long mountain treks exhausting and balanced offhand shooting difficult on your bench. The **MDT® HNT Carbon Fiber Fixed Buttstock (114409BCF / 990482725440)** solves these weight and balance limitations, delivering a high-strength **non-folding carbon fiber buttstock** weighing just 13 ounces.
Proudly engineered and manufactured by MDT Sporting Goods, the 114409BCF is constructed around a high-density, **foam-filled carbon fiber composite shell** paired with lightweight titanium mounting hardware. The specialized foam core absorbs felt recoil impulse and deadens vibration, reducing metallic noise when gear contacts the stock during stalks in the field. Purpose-built for MDT's **XTN chassis interface**—such as the HNT26, LSS GEN3, ACC Elite, and ACC Premier GEN2—this fixed stock features a spacer-adjustable length of pull (LOP) and an integrated cheek riser with 1.0 inch of vertical adjustment. Complete with ambidextrous Quick Detach (QD) sling swivels, this turn-key upgrade provides custom ergonomics directly from your armorer bench.
Engineered to mount natively onto MDT XTN-interface chassis receivers, this factory-calibrated carbon fiber stock delivers exceptional weight savings and recoil damping directly from your workspace bench.
*Armorer Bench Notes & Real-World Ultralight Staging Guidance: The MDT 114409BCF HNT Fixed Buttstock package arrives workspace ready, containing the carbon fiber stock assembly, LOP adjustment spacers, titanium mounting bolts, set screws, and installation hardware. MDT XTN CHASSIS INTERFACE COMPATIBILITY MATRIX: This stock utilizes MDT's proprietary **XTN (E-X-Tended Nose) interface**. *Host Chassis Compatibility Checklist:* Fits natively onto **MDT HNT26, LSS GEN3, ACC Elite, and ACC Premier GEN2 chassis systems**. It will *not* install on standard AR-15 buffer tube threads or carbine receiver extensions without specific XTN adapter modules. Armorer Workbench Custom Staging Sequence: 1. Visually and physically confirm your host rifle is completely clear of live ammunition, the magazine is removed, and the bolt is removed or checked safe. 2. Clean the female XTN mounting socket on your chassis receiver using isopropyl alcohol and a shop towel to clear machining oils. 3. Select your desired Length of Pull (LOP) range by installing or removing the included polymer spacers between the recoil pad and stock body. 4. Align the stock's male XTN boss with the chassis receiver track and insert the included 3/8-24 titanium mounting screw. 5. Apply medium threadlocker (Blue Loctite) to the threads and torque to **35 to 40 inch-pounds** using a hex drive tool on your bench. 6. Loosen the cheek riser thumb screws, adjust the comb height to match your optic centerline, tighten securely, and attach QD sling swivels before rolling downrange.*
