Well that was quick, on line Unertl's origional details.

Rear eyepiece is threaded for " most conventional arpeture" front of the tube open. It uses the rifles regular front which needs to be raised to suit tubes height.

That makes it very likely to be allowed in any iron sight match it's just a tube with adjustment to move mounted conventional rear arp's. Same scope mounts and adjustment as a conventional Unertl. 

J Hands idea mount the front on the tube instead of the gun sounds like a good one too. Avoids modifying the rifles regular front sight.

That's exactly what I did with my Unertl tube sight. The Parker Hale globe sight fit inside the front of the Unertl tube sight perfectly once I removed the dovetail on the sight and slightly polished the OD of the PH globe sight down. It's just a snug push fit, and the knurled collar that is tightened to keep apertures secured makes it easy to grasp and pull out when I change apertures from crosshair to peep.

Mounted couple of my external adjustment scopes on rifles yesterday looking at heights and possibilities. All would require a higher front sight to match a tubes height. Don't want to alter  the windage adjustment fronts of two CPA's each with two barrels. Closest to a height fit was a Unertl 3x small game on a Marlin 39a it showed a little bit of the original Marlin front Ramp Bead and sight hood. Not enough to work.

Seems to me Unertl tube with a slip in arp front is the solution. Have several Lyman 17 fronts, be easy to mill off the base and turn the sight nice and round. Then a turn a sleeve to fit in or around the Unertl's tube.

Thanks all, Looking for a Unertl tube now
