Luth-AR Gunsmith Extractor O' Ring Black, 10 Pack

If you're running a short-barreled AR or dealing with extractor reliability issues, the Luth-AR Gunsmith Extractor O' Ring 10-pack gives you a practical solution without breaking the bank. These black o-rings fit over the extractor spring on .223/5.56 AR platforms and are designed to improve extractor function—especially useful on shorter barrel builds where gas tube pressure can be inconsistent. You get ten rings per pack, so you'll have spares on hand for maintenance or to outfit multiple uppers.

Luth-AR engineered these o-rings from durable, high-quality material built to handle the cycling demands of centerfire rifle use. Installation is straightforward: they simply slide over the extractor spring during bolt assembly. Whether you're troubleshooting a reliability problem, replacing a worn ring, or standardizing your parts inventory, having a fresh set in your toolbox is smart planning.

This is the kind of small-parts insurance that separates a tuned rifle from one that leaves brass on the range. Stock a 10-pack and you're covered for repairs, maintenance, or multiple builds without hunting down replacements when you need them.
