Impact resistant polymer construction provides light weight and resists operational abuse.
Same plane small and large apartures.
Lightweight reinforced polymer construction.
Spring-loaded flip up sight easily activated from either side or by pressing the top.
Detent and spring pressure keeps sight erect but allows for unobstructed folding under impact, etc.
