SOLD OUT, Those who got em will enjoy em!
Cost is $25 a pair, shipped.
The only part you'll need for installation is nuts.
Notice the spacer in the photos of my front pair installed. They are elevated about a half inch. But I like and use them WAY more often than the rear set.
Email me if you're interested in a set.
As far as I've found OEM rings are $20 a pair online and there are some military surplus ones that are slightly different but are pretty cheap. Something like 5 for $5 or something.
BUT THESE ARE BETTER!
