SilencerCo® Charlie Direct Thread Mount – M13x0.75 RH Thread Pitch – Hardened Stainless Steel Core – Low-Profile Black Oxide Protective Finish – Compatible with Omega 36M, Hybrid 46M, Chimera 300, Saker ASR, & Velos LBP Series – AC4745
Product Description
The SilencerCo® Charlie Direct Thread Mount (AC4745) represents a premier mechanical benchmark in NFA silencer host harmonization, ultra-compact suppressor staging, and signature-reduction logistics, masterfully engineered and manufactured by SilencerCo in West Valley City, Utah, USA. Purpose-built to optimize the tracking profile and attachment footprint of SilencerCo's flagship Charlie-spec suppressor ecosystem, this specialized mounting module trades away unnecessary weight and bulk for clean, uncompromising mechanical efficiency. While multi-piece quick-attach mounts (such as standard active ASR collar arrays) provide rapid host-swapping speeds, they introduce additional mechanical joints, complex locking gates, and forward tolerance stack that inevitably increases the total length, weight, and muzzle-heavy bias of your weapon system. The AC4745 direct thread adapter systematically bypasses these operational bottlenecks, transforming your silencer into a sleek, streamlined, and lightweight extension of the barrel.
The foundational performance triumph of this direct thread block relies on its premium high-tensile hardened stainless steel construction bathed in a low-reflective matte black oxide protective barrier. Machined to absolute concentricity tolerances, the robust steel body handles the extreme thermal stress, intense pressure spikes, and corrosive gas scouring characteristic of high-volume centerfire rifle strings. This specific model features an uncommon, precision-cut M13x0.75 Right-Hand (RH) thread pattern, a specialized metric configuration natively engineered to match European-profile threaded host barrels, custom hunting rigs, and specialized precision platform barrels. By threading the suppressor body directly onto the barrel shoulder via this unyielding interface, you maximize the thread-engagement deck, drop overall length by nearly an inch compared to a standard QD assembly, and significantly mitigate backpressure waves inside the gas port tracking loop.
The true tactical victory of this American-machined hardware asset lies within its **broad cross-platform compatibility and absolute alignment uniformity**. Sourcing specialized interface adapters frequently exposes marksmen to point-of-impact (POI) horizontal drift, but this factory OEM Charlie component retains full native architecture threads to seat directly inside the rear housing of the Omega 36M, Hybrid 46M, Chimera 300, Saker ASR series, Saker 556K, and Velos LBP low-backpressure silencers. This rigid steel-to-steel lockup creates a perfectly parallel relationship between the barrel bore axis line and the internal baffle stack, maximizing long-range ballistic tracking while permanently insulating your setup against devastating baffle strikes. Weighing a mass-optimized 3.36 ounces, this premium AC4745 direct thread mount yields total structural, geometric, and technical command over your NFA defensive workspace.

*Administrative Armorer Staging, Concentricity Alignment & Torque Guidance: The SilencerCo AC4745 Charlie Direct Thread Mount is a Class 3 NFA suppressor accessory requiring correct mechanical timing. **CRUCIAL PLATFORM SEATING WARNING:** This mount is engineered exclusively to interface with the rear internal threads of SilencerCo Charlie-profile suppressors; it is 100% INCOMPATIBLE with smaller Alpha, Bravo (HUB), or Delta series silencer housings**. When installing the direct thread adapter into the back of your clean suppressor tube, utilize the factory-provided Charlie spanner wrenches to torque the module securely to 25-30 foot-pounds to prevent the mount from backing out during heat-cycling loops. **BAFFLE STRIKE PREVENTION MEMO:** Prior to launching live centerfire ammunition downrange, always insert a dedicated caliber-matched suppressor alignment rod through the muzzle to visually confirm the bore is perfectly concentric with the internal baffle apertures. Explicitly ensure your host firearm is fully unloaded, the magazine is removed, and the chamber is verified completely safe before initiating workbench adjustments.
Key Features
- Hardened Stainless Steel Monolith: CNC-machined from robust, premium grade stainless steel to completely resist structural yielding and thread degradation under extreme heat load cycles.
- Sleek Low-Profile Footprint: Drastically shortens the overall length and total system weight of your suppressor compared to bulky quick-detach ASR setups, shifting weight back toward the shooter.
- M13x0.75 RH Specialized Threads: Precision-milled thread profile engineered to directly match specialized European-profile threaded rifle barrels and custom tactical hosts.
- Concentric Alignment Security: Establishes a true, flat metal-to-shoulder lockup deck that minimizes point-of-impact shifts and guarantees perfect internal baffle clearance down the bore line.
- Factory OEM Charlie System Fit: Natively threads into SilencerCo Omega 36M, Hybrid 46M, Chimera 300, Saker ASR, and Velos LBP suppressors without requiring aftermarket adapters.
- Black Oxide Chemical Armor: Treated with a deep, non-reflective matte black oxide skin that resists abrasive field scraping, chemical solvents, carbon baking, and rust.
