Disappointed perhaps old stock rubberized cover dry rot right out of the box 1 of four - Vortex SPARC AR 1x22mm 2 MOA Red Dot Sight

I have ordered several of these SPARC for different picatinny rail carbine applications.
The mounting bracket is single point Torx tightened & outdated IMHO.
I would have preferred a QD (quick) double contact lever mount option
Used directly in conjunction with flip up Iron sights on Micro-Roni, Fab Defense Scout & 2 Ruger PC 9's
Sadly I missed the *Optics Planet return period
On this one in particular I noticed the attached lens caps (one piece unit body cover)
would not link together to stay open when in use.
They are extremely brittle.(Like a dry-rotted old tire but not cracking yet)
I am hoping Vortex customer service will replace this unit, the others I have from another vendor function flawlessly.
Perhaps this one was really old stock or a manufacturing issue. The optic seems to work okay,
although I have not compared it side by side with the others I have yet.
I also do not know if it is easy to remove this brittle cover without it tearing.
I will wait to see what customer service states I remain hopeful.
