Silencerco Ac4747 Charlie Direct Thread Mount M18X1 S/S Oxide Black

The SilencerCo AC4747 Charlie direct thread mount is a stainless steel adapter built for shooters who want to attach a suppressor directly to their firearm's muzzle without an intermediate brake or piston system. Designed for M18X1 threaded barrels, this oxide black finish mount integrates the suppressor as a single rigid unit—no moving parts, no added length from a brake. If your rifle or pistol barrel is threaded M18X1, this direct thread solution keeps your setup compact and straightforward.

Direct thread mounts appeal to hunters, precision shooters, and riflemen who prioritize simplicity and durability. Stainless steel construction resists corrosion, while the oxide black finish provides a clean, non-reflective look that works whether you're on the range or in the field. Because the suppressor threads directly onto the barrel, you get a rock-solid connection and the shortest overall length possible—a real advantage in tight hunting blinds or when carrying through heavy brush.

The AC4747 is compatible only with barrels that feature an M18X1 muzzle thread pattern, so verify your barrel's specifications before ordering. Once installed, the direct thread design makes for easy field cleaning and maintenance. If you're building a suppressor-ready rifle or upgrading an existing barrel, this mount gives you the mechanical simplicity and low-profile mounting that serious shooters demand.

Frequently Asked Questions

Will this mount work on my rifle?

The AC4747 fits only barrels with M18X1 muzzle threads. Measure or check your barrel's specifications to confirm before ordering. Direct thread mounts are not transferable between thread patterns.

Do I need a suppressor already, or does this come with one?

This is the mount adapter only. You will need to pair it with a compatible SilencerCo suppressor. The direct thread mount connects the suppressor to your M18X1 barrel.

What's the advantage of direct thread over a brake mount?

Direct thread eliminates the intermediate brake and keeps your setup as compact as possible. You get a shorter overall length, simpler mechanics, and a rigid one-piece connection with no extra components to maintain.

How do I maintain or clean this mount?

Because it's stainless steel, you can clean it with standard gun-cleaning procedures. The direct thread design makes it straightforward to remove and reattach your suppressor for field maintenance or barrel cleaning.
