Nope..flat based

Flat on top only or flat on top and both sides?

Many airguns, today, are flat on top with a dovetail groove on each
side to take an airgun-style clamp-on scope/aimpoint/laser sight.
(The dovetail runs the length of the receiver instead of
perpendicular to the receiver.)

A short stop at a Wal-Mart will give you an idea of how these things
attach since they carry both airguns and airgun scopes/mounts.


Flat on top of the barrel. Im not a big fan of putting a optical
sight on top of something not firmly attached to the tube the
projectile comes out of.

Break action spring guns come to mind as one of the major cases.

That barrel gets even a bit wobbly, doesnt lock up to the receiver
each and every time the same way...that optical sight is worthless


And, yet, that's the normal attachment: the receiver instead of the
barrel.

That's why the grooving is on the receiver.

By using a standard mount, an airgun scope/aimpoint is easily mounted
and zeroed.

However, you might want to fabricate clamp-style mounts for a
long-eye- relief (pistol) scope by bending 4 strips of metal so that
the spacing is uniform, the bends match the OD of the scope barrel and
the rifle barrel, and use a machine screw/wingnut combination in the
middle.

That'd be the simplest way to get a mount that would meet your stated
requirement.

Not a bad idea. Though Id machine a clamp mount rather than use sheet
metal

You'll need to use a pistol-type long eye-relief scope if you go with a
barrel mount.

FWIW, on the site someone else supplied (an airgun sales site) they had a
clamp-on 3-track mount that may give you some ideas. grin

Of course, you might want to experiment with simply drilling and tapping
the flat on top of the barrel to enable use of standard Weaver or
Redfield bases. (You might have to grind/mill the basees' underside
flat.)
