Luth-AR Part Bolt Gas Rings 30 pack BT-01-30P UPC 859992007968
Product Description
The Luth-AR Bolt Gas Rings 30-Pack (BT-01-30P) is a bulk contractor-quantity replacement parts package engineered for armorers, gunsmiths, and high-volume AR-15 builders. Designed to restore critical gas pressure sealing inside Mil-Spec bolt carrier group (BCG) expansion chambers, this 30-pack provides enough gas rings to re-ring up to 10 individual AR-15 bolt tail assemblies.
Precision CNC-machined from heat-treated steel to strict Mil-Spec dimensions, the BT-01-30P gas rings fit standard 5.56 NATO, .223 Rem, 300 Blackout, and 6.5 Grendel bolt tails. Over time and high round counts, gas rings experience wear, erosion, and tension loss—leading to gas blow-by, short-stroking, and cycling failures. Keeping fresh gas rings on your armorer bench ensures immediate restoration of factory gas efficiency and bolt carrier velocity.
Finished in a protective Mil-Spec black phosphate coating for maximum corrosion resistance and oil retention, Luth-AR bulk gas rings deliver clean sealing, consistent spring tension, and long-term durability across all hard-use defensive, competition, and duty rifle setups.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits standard Mil-Spec AR-15 bolts (5.56 NATO, .223 Rem, 300 AAC Blackout, 6.5 Grendel, .204 Ruger). (Note: Provides 30 individual rings, suitable for completely servicing 10 AR-15 bolt assemblies).
- Perform a complete firearm safety check: drop the magazine, lock the bolt rearward, and visually inspect the chamber to verify zero live rounds are present.
- Disassemble the upper receiver, remove the Bolt Carrier Group (BCG), and strip the firing pin, cam pin, and bolt from the carrier.
- Using a fine pick tool, carefully strip the three worn gas rings from the tail of the bolt body.
- Thoroughly clean carbon deposits from the bolt tail channels and the interior expansion chamber of the bolt carrier.
- Stagger-install three new LBE/Luth-AR gas rings into the bolt channel, ensuring the gaps on each ring are offset from one another (do not align gaps).
- Perform the standard armorer gas ring test: fully assemble the bolt into the carrier and extend it forward. Stand the BCG vertically on the bolt head—if the carrier collapses under its own weight, the gas rings require replacement. Fresh rings will hold the carrier extended.
