Burris fastfire 4

Selling an excellent condition burris fast fire 4 reflex sight. Just needs a battery (CR1632) and it's good to go. I left the sight on and it died. It was mounted on shot gun for one range visit. And they are awesome.  

I have another burris 4 on my beretta 1301 tac and it handles wicked. I love it! But I don't need 2 I took this one on trade.

Asking $425.00 shipped
