s-boy, that rifle doesn't see much use, so "no", no Alumina caps for this one, just a bikini cover.
However, all my primary CF varmint and BG rigs wear Alumina caps. One nice feature they have is that the objective cover folds flat, thereby not obscuring your vision downrange.
They seal out dust very well, seal with o-rings and rare earth magnets....very well made:
They really do "finish off" a nice rifle and sure are functional:
Only problem is that once you get your first set, you'll want them on all your scopes. ($=
