Q Direct Mount Erector9 M13.5-1l

The Q Direct Mount Erector9 M13.5-1L is a direct-thread muzzle device adapter engineered for shooters who want to run their Q Erector9 suppressor on fixed-barrel firearms. If you've got a precision rifle, pistol, or other firearm with a permanently affixed barrel and an M13.5x1 left-hand threaded muzzle, this adapter lets you mount Q's modular Erector9 without permanent modification to your gun. It's straightforward: thread it on, attach your suppressor, and you're running one of the most versatile suppressor platforms available.

Built from 17-4 stainless steel and treated for durability, the Direct Mount Erector9 is light enough not to throw off your rifle's balance—it weighs just over an ounce—yet robust enough for serious use. Whether you're shooting subsonic loads for hunting, running a suppressed rifle at the range, or setting up a dedicated precision platform, this adapter gives you the flexibility to use Q's Erector9 ecosystem on barrels that would otherwise lock you into a different mounting solution.

Q's direct-thread approach keeps things simple: no barrel-mounted collars, no extra parts in your kit. If you're already familiar with Q suppressors or you're building a rig around one, the Direct Mount Erector9 is a no-fuss way to add compatibility to a fixed-barrel gun. Just confirm your barrel's thread pitch before ordering—this one is cut for M13.5x1 LH specifically.

Frequently Asked Questions

Will this work on my rifle?

Only if your barrel is threaded M13.5x1 left-hand. Check your barrel's thread pitch and rotation direction before purchase. If you're unsure, contact the rifle manufacturer or a gunsmith.

Does this come with the Erector9 suppressor?

No, this is the direct-mount adapter only. The Q Erector9 suppressor is sold separately.

Can I use this on a removable-barrel firearm?

This mount is designed for fixed barrels. If your barrel is removable and you want Q suppressor compatibility, you may want to explore other mounting options.

Is this left-hand thread only?

Yes, this adapter is cut for M13.5x1 left-hand thread. Q also makes right-hand versions if your barrel is threaded that way.
