$3 gas rings.
They are what they are. Picked up an extra set in case I ever need them. I’ll always do business with Arms Unlimited since they shipped my standard mags during freedom week here in California.

Good Rings bus dissapointed with customer service
Ordered Gas Rings on Sunday, expected to receive them by the following Friday or Way earlier, since I'm in L.A. and Arms Unlimited is in Las Vegas. Didn't receive the rings until 1 week and a half after. There shipping department needs to pick up the pace. Otherwise, good selection of products

Colt M16/M4/AR15 Bolt Gas Rings
I like to keep spare parts. I've purchased many items from Arms Unlimited. AU is always my go-to source if they carry what I'm looking for. Their prices, fast delivery and service are second to none.
