Compact Prismatic

- 

When I see special forces soldiers or police firearm units on the television these days I often look at the weapons they carry to see what’s new, and all too often they’re carrying Colt M4 variants. These tend to wear what appear to be ultra-compact prismatic scopes that deliver superior accuracy compared to open sights or red-dot units. The most well known of these is the Trijicon ACOG, a design that has been copied by many other manufacturers.
