Gemtech Spacer for .22LR Longer Threaded Barrels – 1/2x28 Suppressor Alignment

Keep your suppressor safe and secure. The Gemtech Spacer for .22LR longer threaded barrels solves the common issue of extended thread length, ensuring your rimfire suppressor seats correctly and avoids dangerous baffle strikes. Precision-machined and built for 1/2x28 threaded barrels, this spacer guarantees proper alignment and flush mounting every time.

Product Overview

Some .22LR rifles and pistols come with threads longer than the rimfire industry standard. While this may not matter for other muzzle devices, it can prevent suppressors from seating properly, leading to gaps, misalignment, or even strikes inside the blast chamber.

The Gemtech Spacer corrects this issue by reducing excess thread length and creating a true shoulder for your suppressor. Compact, durable, and easy to install, it’s the simplest way to protect your gear and maintain accuracy.

Key Features

• Thread Pitch: Designed for 1/2x28 TPI rimfire barrels

• Compatibility: Works with .22LR suppressors and many rimfire hosts with extended threads

• Purpose-Built: Prevents baffle strikes caused by longer-than-standard threading

• Construction: Precision-machined steel for durability

• Finish: Black nitride coating for corrosion resistance

• Installation: Simple drop-in spacer between barrel shoulder and suppressor

Why Choose This Spacer?

Suppressor safety and performance depend on proper fit. Without a spacer, an extended threaded barrel can create dangerous misalignment, harming both your suppressor and your firearm. The Gemtech Spacer provides:

• Correct seating depth for suppressors on .22LR and rimfire barrels

• A flush fit that maintains consistent accuracy

• Reliable compatibility with most rimfire hosts threaded in 1/2x28

Whether you’re running a suppressed .22LR pistol, AR-style rimfire carbine, or custom build, this spacer ensures your setup works as intended.

FAQs

Q: Why do I need a spacer for my .22LR barrel?
Some barrels are threaded longer than the rimfire standard. A spacer corrects the length so suppressors seat properly.

Q: What thread spec does this spacer support?
It’s made for 1/2x28 TPI, the common standard for rimfire barrels.

Q: Will this prevent baffle strikes?
Yes. By ensuring proper suppressor seating, the spacer reduces the risk of misalignment and strikes.

Q: Can this spacer be used on other calibers?
It is optimized for .22LR and rimfire platforms. For centerfire calibers, use a spacer designed for that application.

Q: How do I know if I need a spacer?
If your suppressor doesn’t seat flush or if there’s extra barrel thread protruding inside the mount, you likely need a spacer.
