Burris fast fire red dot mount - Burris FastFire Reflex Red-Dot Sight Mounting Plates

I put this dovetail mount on my Ruger mkiii. Easy to install. Fits the contour of the gun perfectly. I placed my order March 1st. Started worrying after no more tracking updates after the fifth. Then, when I hit the tracking botton on the email, it kept saying "we don't know where this order is".I thought sure it had gotten lost. Then today, March 11, it just showed up in my mailbox,so it's all good.
