When you get what you paid for...! - Crimson Trace MVF-515 Modular Vertical Foregrip Laser Sight For AR-15 Rifles

The construction of the grip and "light" elements are sturdy and machined to fit tight. Simple instructions to follow if its not intuitive..This purchase has not diappointed my expectations.
Pros: It is what they claim it is, from all aspects.... it's built right
Cons: ...haven't discovered any to date.
