By The Numbers - Springfield - Saint B5 - 5.56 NATO

A mediocre trigger is the limiting factor here
Extremely reliable
AR-15 means near infinite customization, but the front sight block does make things a little more difficult
The B5 systems furniture feels great in the hand
While reliable and well-equipped, a full-length handguard and a better trigger would serve this gun well
