We have a few different versions of this classic ARMS sight. This is by far the most desirable. It has the bayonet lug, and is permanently pinned in-place by a competent gunsmith. This is not a do-it-yourself-er. This is one of my favorite front sights. I use this on the SAM-R, because I am not spending $1,600 of your money for a KAC front sight, when this one is better, and looks very similar.
New, in factory packaging.
This item requires gunsmith installation. This needs to be drilled and pinned by a qualified gunsmith. It does not come with taper pins.
