The CMMG Zeroed Adjustable Gas Block Kit is a maintenance and rebuild solution for shooters running CMMG's Zeroed adjustable gas block system. Whether you've logged thousands of rounds and want to service your block, or you've had a detent spring take a walk downrange (it happens), this kit puts you back in the fight without replacing the entire assembly. It's a smart way to keep your adjustable gas system running reliably without the downtime or expense of a full replacement.
Adjustable gas blocks are workhorses on modern AR platforms, letting you tune your system for different loads, suppressors, and shooting conditions. The Zeroed design is known for its straightforward operation, but like any mechanical component under pressure, internal parts wear or get lost. This kit includes every internal component you need to restore your gas block to factory spec, making it an essential spare for serious shooters who demand consistency.
Keep this kit in your range bag or shop drawer. It's light, compact, and saves you time when a quick rebuild is all that stands between you and getting back on target. For AR builders and shooters committed to their Zeroed system, having replacement internals on hand means zero excuses for downtime.

Frequently Asked Questions
Will this kit fit my CMMG Zeroed adjustable gas block?
Yes, this is the official CMMG maintenance kit designed specifically for Zeroed adjustable gas block bodies. It includes all internal components that go into the Zeroed system.
What's included in this kit?
The kit contains an adjustment screw, detent, detent spring, and a gas tube roll pin (.078 x .313 diameter). These are all the internal parts necessary to fully service or rebuild your gas block.
Do I need to replace my entire gas block, or can I just use this kit?
This kit is designed for gas block bodies that are still in good condition. If your block body is damaged, you'll need a full replacement. But if you've lost or damaged internal components, this kit lets you keep your existing body and restore full function.
What if I've lost a spring or screw downrange?
That's exactly what this kit is for. The detent spring and adjustment screw are common casualties during range sessions. Having this kit on hand means you can get back to shooting without waiting for replacements.
