Description
Cross-threaded the mount on your Erector 22? It happens more than anyone likes to admit, especially with a modular can that gets taken apart and reconfigured as often as this one does. This is the factory replacement mount from Q, threaded 1/2-28 to fit the vast majority of rimfire barrels and muzzle devices out there. Spin off the damaged or worn original, thread this one on, and your Erector is back in business.
Why Keep a Spare Erector 22 Mount Around
The Erector is one of the most modular rimfire suppressors ever made, and all that assembly and disassembly means the mount sees more handling than a typical fixed-mount can. Threads take abuse over time, small parts wander off during cleaning sessions, and a mount left in the solvent tank at home does you no good at the range. Having a spare tucked away means a fumbled part never cuts a shooting day short. It weighs next to nothing, so there's no downside to stashing one with your cleaning kit.
Built to Match the Original
This is a genuine Q part, not an aftermarket knockoff, so fit and thread engagement are exactly what your Erector 22 was designed around. The clear hardcoat anodized finish stands up to repeated mounting, carbon fouling, and the lead-heavy grime that rimfire cans are famous for collecting. Since it matches the factory spec, there's no guesswork about alignment or compatibility with the rest of your baffle stack.
Simple Install, Standard Threads
Installation is as straightforward as it gets: the mount replaces the original directly and threads onto any 1/2-28 muzzle. That covers most .22 LR pistols and rifles with threaded barrels, from a Ruger 10/22 with an aftermarket barrel to a threaded Mark IV. If you run your Erector across multiple rimfire hosts, this little part is the piece doing the connecting, so it's worth having a fresh one on hand.

Frequently Asked Questions
Will this mount fit suppressors other than the Q Erector 22?
No, this is a dedicated replacement part designed specifically for the Erector 22 rimfire suppressor. It is not intended for the ERECT9R or other cans from Q or any other manufacturer. If you own a different suppressor, look for the mount made for that specific model.
What barrels will the 1/2-28 thread pitch work with?
1/2-28 is the standard thread pitch for the vast majority of .22 LR threaded barrels, including popular hosts like the Ruger 10/22, Mark series pistols, and most rimfire uppers. If your barrel is threaded 1/2-28, this mount will screw right on. Always confirm your barrel's thread pitch before mounting any suppressor.
Why would I need a replacement Erector 22 mount?
The most common reasons are cross-threading the original during reassembly, worn threads from frequent takedown, or simply losing the part during cleaning. Since the Erector comes apart into a lot of small pieces for maintenance and length changes, a spare mount is cheap insurance. Plenty of Erector owners keep one in the range bag just in case.
Is this a genuine Q factory part?
Yes, this is an original replacement mount made by Q LLC, the same company that builds the Erector 22 suppressor. It matches the factory specs and clear hardcoat anodized finish of the mount that shipped with your can, so fit and function are identical to the original.
