Troy Front Folding Sight HK Style

Easy to install and to deploy, with no levers or springs to fumble with, these sights position apertures at exact factory height. A stainless steel cross-locking system ensures sights remain upright and zeroed under extreme combat conditions. A push of a button folds the sights securely out of the way until you need them again (they fold to a profile of just 0.460). Troy BattleSights feature a zero-canting attachment system for use on all military and aftermarket receivers. No tools required for adjustment. Each click adjusts .50 MOA. Note: Will not work on railed front gas block mounted lower than receiver height.
