Iron Sights (BUIS)

Back Up Iron Sight Selection from Operation Parts

Here you will find all of the backup iron sights (BUIS) that we carry for AR-15 / SR-25. View real-time inventory on M4 sights, M16 sights and a variety of AR 15 sights, which can either be used alone or in conjunction with a red dot scope. We carry both fixed and fold down/flip up versions that can be stored in the down position when only the red dot is required. They can quickly be deployed if the red dot were to go down. We carry AR15 iron sights made by A.R.M.S., GG&G, LMT-Lewis Machine & Tool, KAC-Knight's Armament, PRI-Precision Reflex, Troy Industries, Vltor, and YHM-Yankee Hill Machine.
