This is an OEM mil-spec snap ring to hold the delta ring + weld spring combo in place. This part has special contours and thus is not recommended to be replaced with an off-the-shelf snap ring from your local hardware store.
- Mil-spec blackened spring steel
- Specially designed for the AR-15/M16 platform
- Weight: 5g
- Dimensions: Ø40 × 1.4mm (diameter × thickness)
- One snap ring for your hand guard
- Mil-spec barrel nut
Tools required: Snap ring pliers would be super useful
Installation notes: This can be done with a flat screwdriver if you are a patient gunnie but really snap ring pliers would prevent a lot of swearing

Invest in Those Split Ring Pliers
Definitely a snug fit. Have the pliers on hand so you don't have to go for a drive to the Hardware Store out of frustration like I did!
