• Spring pressure keeps sight erect, but allows for unobstructed folding under impact, etc.
• Sight clamps to most any MIL-STD-1913 Picatinny/STANAG 4694 railed hand guard
• Sight provides the same height-over-bore as standard A2 iron sights
• Protective wings shield the spring-locking A2 front sight post
