Luth-AR AR-15 Bolt Gas Rings Features The Luth-AR Bolt Gas Rings are built specifically for .223 Rem and 5.56mm AR-15 bolts sealing gas within the gas tube so pressure is directed where it belongs instead of leaking out around the bolt. Reliable gas sealing is critical to consistent cycling and worn or damaged rings are a common cause of short-stroking or failures to lock back. Made from durable high-quality materials these rings are designed to hold up to repeated firing cycles without losing their sealing properties. The silver finish matches factory bolt carrier group components for a clean consistent appearance. Each package includes 30 rings giving owners or armorers plenty of replacements on hand for routine maintenance or multiple builds. Installation is straightforward and compatible with most .223 caliber AR-15 rifle platforms making these rings a practical addition to any range bag or parts kit. Whether replacing tired factory rings or simply keeping spares ready for the next cleaning session Luth-AR s gas rings offer a reliable affordable way to maintain smooth rifle operation. They are a sensible upgrade for anyone who wants to avoid unexpected reliability issues at the range.
