Keep your Stealth Recoil Spring in Check with Replacement O-Rings

The Armaspec Stealth Recoil Spring uses a rubber O-Ring to reduce metal-on-metal contact with the buffer weight and the rear face of your AR15’s bolt carrier.  If the O-ring wears down faster than expected, or you anticipate heavy use, this 3-pack of O-rings will ensure your bolt carrier will not wear excessively against the buffer weight.

Prop 65 Warning: This product can expose you to chemicals including lead, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to

Backup Rings

Read on a previous review that a user had these rings chewed up faster than he anticipated; ounce of prevention mindset had me buy these, but with the excellent quality of the basic product, these rings would be the ONLY part of the whole assembly that you would have to worry about, if at all.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase. Cheers!
