Magpul MBUS knockoffs

I believe these function the same as MBUS but they have a nice QD feature for toolless removal or installation,  just depress the button on the side and they can slide on and off with ease.  Spring loaded for quick and easy deployment.

Painted the front iron sight white for better visibility. It is on a metal front sight post so easily removed with some alcohol or paint thinner.  

Shipping available.
