Strike Industries® Strike Modular Chassis (SMC) Alpha MKII Full Aluminum Chassis System – For Sig Sauer® P320 Handguns – V2 Flex-Corrected Architecture – Anodized Black – SI-SMC-A-P320-S-V2-BK
Product Description
The Strike Industries® Strike Modular Chassis (SMC) Alpha MKII Full Aluminum Chassis System (SI-SMC-A-P320-S-V2-BK) represents an unmatched structural milestone in modular handgun logistics, micro-carbine transformation economics, and severe-duty tactical component staging, proudly designed and engineered in the USA. Specifically developed to exploit the latent multi-patented modularity of Sig Sauer’s standalone Fire Control Unit (FCU), this premium conversion system gives marksmen the power to instantly morph an ordinary striker-fired sidearm into a high-stiffness personal defense weapon (PDW) layout. While standard polymer frameworks flex under hard cyclic pressure and suffer from rapid muzzle rise—prolonging your split-second target-reacquisition loops—the SMC Alpha MKII establishes an ultra-rigid metal foundation. This overbuilt billet workspace (793811767650) yields complete administrative and tactical authority over your platform, adapting smoothly into personal protection roles, vehicle staging kits, and dynamic competition lines.
The core engineering triumph of this second-generation (V2) system relies on its monolithic 6061-T6 aircraft-grade billet aluminum construction and advanced structural revisions. Sourcing feedback from first-generation extreme deployment cycles, Strike's engineers fundamentally overhauled high-stress focus tracks to prevent component fatigue. The Alpha MKII features an up-armored, thicker multi-optic mounting deck that completely neutralizes lateral flexing under rapid fire, alongside a reinforced, heavy-duty ambidextrous extended side charging handle that will not crack under hard manual racking vectors. The frame's dust cover length is carefully cut to full-size standard parameters, sitting flush with a 4.7-inch factory slide assembly. For operators looking to run shorter compact slides, this rigid chassis serves as a native interface for direct-mount muzzle devices like the SMC Alpha Comps or heavy blast shields, which route high-pressure gases clean away from the frame without requiring a threaded barrel.
The true tactical victory of this American-engineered powerhouse lies within its **built-in dual payload capacity and comprehensive modular backstrap ecosystem**. Out of the box, the system ships completely configured with a **forward-mounted spare magazine holder with its own integrated, extended magazine release button**. This forward station serves dual mechanical purposes: it acts as a hyper-stable vertical thumb-rest anchor to manage recoil vectors while keeping an immediate 17- or 21-round secondary payload staged right at your fingertips. The rear receiver block includes both a streamlined Backstrap Lite and a heavy-duty **Picatinny Rail Backstrap block**, giving you a rigid 1913 interface to securely attach folding stocks or pistol stabilizing braces. Outfitted with multiple ambidextrous QD sling swivel sockets and an all-inclusive multi-optic footprint plate matching RMR, DPP, C-MORE, and Docter layouts, this 11.29-ounce conversion masterpiece gives you absolute operational control over your defensive shooting workspace.
Includes: (1) Authentic Strike Industries SMC Alpha MKII Full Aluminum Grip Module Chassis (Anodized Black, Dual-Sided Extended Magazine Releases Installed), (1) Picatinny Rail Backstrap Module with QD Sockets, (1) Backstrap Lite Overlay, (1) Multi-Optic Footprint Mounting Plate with Screw Set, (1) V2 Slide Cover Mount, (1) Extended Ambidextrous Side Charging Handle with Rubber Contact Pads, and (1) Spare P320 Magazine Holder Station, packed inside an Original Branded Factory Sealed Protection Box.
*Administrative Installation, Barrel Clearance & Local Regulation Guidance: The Strike Industries Alpha MKII is a bare modular conversion chassis; it **does NOT include the internal chassis Fire Control Unit (FCU) or slide components**, requiring you to drop in your own existing non-manual safety P320 trigger group to create a functional system. **CRUCIAL SLIDE AND MUZZLE BLAST WARNING:** This full-length frame's dust cover sits perfectly flush with a full-size 4.7" barrel and slide. If you install a compact 3.9" or sub-compact 3.6" slide, **you must install an SMC Alpha Comp or an extended threaded barrel with an aftermarket muzzle device to extend past the front frame gate; firing a short slide uncompensated inside the bare chassis will channel hyper-velocity muzzle blast directly inside the aluminum walls, causing permanent structural failure and voiding your warranty**. Always check local state and municipal regulations regarding pistol-to-carbine conversion modifications before final staging. Ensure your host handgun is completely unloaded, cleared, and safe before starting bench assembly loops.
Key Features
- Up-Armored Monolithic Aluminum Core: CNC-machined entirely from a solid billet of 6061-T6 aircraft-grade aluminum to permanently stop frame torque and structural deflection.
- V2 Flex-Corrected Optic Deck: Redesigned multi-optic footprint mount features a thicker, reinforced base plate to ensure zero dot distortion or twisting under automatic fire.
- Heavy-Duty Ambi Side Charger: Upgraded ambidextrous slide charging mechanism utilizes rubberized contact pads to optimize fast manual slide cycling from either hand.
- Dual Backstrap Modular Adaptability: Packages both a streamlined Backstrap Lite and a MIL-STD 1913 Picatinny Rail Backstrap block to mount folding stocks or braces instantly.
- Staged Spare Magazine Station: Includes a detachable forward mag holder with a dedicated extended mag button, doubling as a high-leverage forward grip stabilizer.
- Universal Optic Footprint Script: Pre-drilled steel retention posts drop down seamlessly to direct-mount Trijicon RMR, Leupold DPP, Docter, C-More, and Shield red dots without intermediate plates.
