FS: Rear Picatinny Red Dot Mount.

Post by Fred » Thu Oct 17, 2019 5:26 pm

So I made a couple of these picatinny bases for our Model 8 or 81 autoloading rifles. It should be a reversible modification primarily for the addition of a red-dot or reflex sight. You should be able to use your factory nut-plate and rear sight screws to install it.

I'm asking $30 shipped. If you think that's unreasonable, feel free to make an offer instead.

I prefer USPS money orders but if you're in a hurry I can do paypal if you pick up the fees.

More details:

These are 5 slots long but I can make them a little longer if you need. It's just that there's two little factory screws 5/8" apart holding everything on so I don't recommend going overboard. These bases are 6061 aluminum and partially anodized except where I machined them.

For me, using a 3-MOA Burris Fastfire III my sight picture is just were I need it for shooting off-hand on my M81. It should probably be lower for shooting prone. I could make the bases lower, but then you get into issues with the ~.270" long factory screws sticking up into the slots or the screws hitting the barrel inside the jacket. If the screws sticking up some into the slots is not an issue then I can make the bases shorter. I'm willing to work with you.

The bases' inside radius is a little smaller than .500" so its outside edges will ride the 1" diameter barrel jacket. While I don't think it's necessary, you can use some sand paper and a dowel (or a deep socket) to get the fit a little tighter or you can use a little bedding compound to fill the ~.007" gap. I do recommend a little blue loctite on the screws though.
