Q built the Erect9r to be one of the most adaptable 9mm cans out there, and this direct mount is the piece that opens it up to a whole new group of hosts. The Erect9r ships set up with a booster for tilt barrel pistols, but that piston system has no business on a fixed barrel gun. That is exactly where this 1/2-28 direct thread mount comes in. Pull the booster, thread this on, and your Erect9r is ready to live on a pistol caliber carbine, 9mm AR, subgun, or any other fixed barrel host wearing 1/2×28 threads.
The build is simple and stout. Q machines this mount from 17-4 stainless steel and heat treats it, so it shrugs off the blast and heat right at the muzzle where a mount takes the most abuse. At 1.12 ounces, it also trims weight compared to running a full booster assembly, which keeps the whole setup lighter and better balanced on a carbine. Since 1/2×28 is the standard thread pattern for most 9mm barrels, this version covers the widest range of hosts in the Erect9r mount lineup.
Installation is about as straightforward as it gets. Remove the piston and booster from your Erect9r, install this mount in its place, and thread the suppressor onto your barrel. One thing worth repeating from Q themselves: if your host has a fixed barrel, do not run the Erect9r with the piston. The recoil booster exists to help tilt barrel pistols cycle, and a fixed barrel gun does not need it. Running the direct mount instead gives you a solid, repeatable connection with no moving parts to fuss with.
If you picked up an Erect9r and want to stretch it across more of your safe, this little chunk of stainless is a smart add. It is small, tough, and does exactly one job without complicating anything.
It lets you run the Q Erect9r 9mm suppressor on fixed barrel firearms with 1/2×28 muzzle threads, like pistol caliber carbines, 9mm ARs, and subguns. The Erect9r comes from the factory with a booster assembly for tilt barrel pistols, and this mount replaces that setup for fixed barrel use.
No, and Q is very clear on this point. The recoil booster is designed for tilt barrel pistols that need help cycling, and running the piston on a fixed barrel host can cause problems. Swap in this direct mount whenever the suppressor is going on a fixed barrel firearm.
If your 9mm barrel is threaded 1/2×28, which is the most common pattern for 9mm hosts in the US, this is the right version. Q also makes the Erect9r mount in M13.5×1 LH for guns like certain imported pistols, plus a tri-lug option, so double check your muzzle threads before ordering.
The direct mount comes in at just 1.12 ounces of heat treated 17-4 stainless steel. That is lighter and simpler than a full piston and booster assembly, which helps keep an already light suppressor like the Erect9r from throwing off the balance of your carbine.
