As IR filters go, this one is top notch. Very well constructed,. stout housing, no light leakage at all even when aggressively working the action or firing. Seats well, does not lock back when not deployed.
Pros: Solid Construction, flips open easily and stays open
Cons: no detent to keeep top flipped open, cost
