Very robust - Midwest Industries Combat Rifle Offset Deployable Iron Sight

Very robustly built, very precise, and a good solution to not having a quick detach scope mount. They’re easily adjustable as much as a standard mil-spec m16/m4 iron sites, plus, you can replace front site post if wanted. They fold out quickly with nice friction, thus, hold retracted with sufficient friction. I’d definitely recommend anything from Midwest Industries—no I don’t get sponsored by them just a small time end user here.
