Dovetail V.S. Picatinny V.S. Weaver

[KK0605]

BKL makes a dovetail to weaver adapter. Its nice, with the 6 screws that hold it down. With hardly any picatinny adapters out, this might be a good 2nd option.

[thebookdoc]

It is $45 for the adapter and it is not adjustable... The 6 screws are attractive, but I think the Hawke will stand up fine -- and the whole setup with rings is $30. I forgot to take pictures last night. Hopefully tonight!

If I knew this would work I would get it. I don't need adjustable right now. And it is so low. It says 6 set screws, no gun smithing required. I could cut it down if it was too long. Price is ok for me.

The pictures do not make clear how that attaches. if you don't need any adjustable, looks like it'd be fine -- IF you can get it on.

I am guessing that the screws might push down a second piece that locks the base? I know I had trouble getting an 11mm dovetail rail to stay in place...

This could be a 'prettier' solution...

[KK0605]

I'm guessing that the screws go into Marlin specific holes that are drilled at the factory. Another let down!

[thebookdoc]

I am tempted to put together a design and see how much it would cost to create a prototype...

[KK0605]

That prototype on the video was perfect, if it had kept the dovetail base. It was picatinny, adjustable, and heavy duty. It could have been lower though.  If you made one, I would definitely buy one.

Marlin model 60's don't have drilled and tapped holes in their receivers. The mount slides on from the front of the receiver and then the screws push against the receiver to lock the mount to the receiver's dovetail rail. It would seem the mount can only be used in a application where at least one end of the dovetails is open to allow the mount to slide on rather than clamp on. Don't think this mount will work on a springer unless it has a seperate scope rail attached to the tube.

Check this adapter. It says Weaver, but looks like Picatinny.

Well, the TF89 has somewhat open dovetails. They allow the rail to slide on. Yes, that adapter is for weaver/picatinny. But, what does weaver/picatinny mean? picatinny or weaver? a mix would not be the right size for either.

Maybe that Marlin rail would work. I'll see if they offer returns if it doesn't work...

[thebookdoc]

I believe the Weaver/Picatinny type just means that it is Picatinny but they can also accept Weaver mounts -- they just have to go on Picatinny spacing.

Technical specifications

In order to provide a stable platform, the rail should not flex as the barrel heats and cools; this is the purpose of the spacing slots: they give the rail considerable room to expand and contract lengthwise without distorting its shape. The Picatinny locking slot width is 0.206 in (5.232 mm). The spacing of slot centers is 0.394 in (10.008 mm) and the slot depth is 0.118 in (2.997 mm).[1] The only differences between the Picatinny rail and the similar Weaver rail are the size of these slots and the fact that they are standardized. Weaver rails have a slot width of 0.180 in (4.572 mm), but are not necessarily consistent in the spacing of slot centers.[2] Because of this, accessories can be and are designed to fit on both Weaver rails and Picatinny rails; but most Picatinny devices will not always fit on Weaver rails.

[KK0605]

Yes, so I guess i should put some facts in order.....

1. Weaver/Picatinny COULD be a picatinny rail that fits Weaver also.
2. There are no Dovetail to Picatinny ONLY adjustable rails.
3. The Marlin rail fits the "tip-off"/dovetail rail that comes on Marlin's with drilling.

Here is something I found. http://www.leapers.com/production/prod_detail.php?mitem=Mounting%20Systems&level1=Airgun&level2=Rail%20Adaptor&itemno=MNT-DNTOWL&status=
Do RWS guns have there own style of dovetail???

[thebookdoc]

The rail on the RWS guns is raised rather than being a groved receiver. The lip on the end of the rail you show sets in front of the rail on the gun, and keeps the mount from sliding backwards.

[thebookdoc]

BTW -- a product I tried but could not get to stay nicely on grooved receiver....

Maybe some Loctite or the ever-popular Rubber Cement (if you can still find it)? One thing about the Gamo rail - it's aluminum and bases/rings with stop pins have been known to egg the holes on more powerful Gamo springers.
