Anyone know of any rebuildable, anodizable, low-profile detents other than the RPG Re-tent? I say "other than" only because I seem to have a hard time actually buying a set of re-tents.

What I'm looking for in a detent is something that just works without being noticed, and longevity. Hence, the request that it be able to be anodized to blend in, and rebuildable so that it can be maintained instead of thrown away if something happens.
