Troy SSIGFBSFHFT Battle Sight Front Folding Flat Dark Earth

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.
