I was hoping to accomplish two objectives with this project - 1) to make the markings on the AO ring readable from the shooting position, instead of having to shuffle the rifle around to look at the top of the tube, and 2) to attempt to make the yardage markings a bit more legible, and spaced apart. Objective #2 was hampered somewhat by the close proximity of the focus ring to the compression chamber, but helps a bit.

Pic #1 shows the collar, installed, with the new swept forward pointer located on the left side of the scope bell. The yardage markings wil be made radially around the tapered section of the collar. The grooves in the collar makes for much smoother and easier turning of the AO.
Pic#2 shows the minimal clearance between the collar and the compression chamber of the FWB 300S.
Pic#3 shows the AO set to the 10 yard position, and the relationship of the swept forward pointer. From the "driver's seat", the gap is not noticeable.
Pic #4 shows the AO set at infinity. It can not be seen clearly in the pic, but the pointer is approximately 0.015" away from the face of the collar.
Pic #5 shows how things appear from the "driver's seat". The collar is set at the 25 yard position. Both the level and the ranging marks can easily be seen from the shooting position.
I still have to paint the pointer and it's mounting strap, and I have to apply some paper to the tapered section on the collar for the range markings.

Has anyone ever seen/considered a right-angle prism mounted to one side, with the marking tape in the standard position? Done properly, it would be very slick, compact and easy to read. Scribe a rule on the side facing the bell to eliminate parallax problems. Markings would have to be dual/mirrored...

That sounds cool, but a big objective here (get it, big objective!) is to increase the circumference of the 'wheel' thus increasing the distances between each yardage mark.

Thats why people with a side focus purchase the large 5 or 6 inch wheels.

For front focus scopes, your only solution is to mount the scope higher.

Supr, great job!

Objective collar for my FT scope.......

Very neat concept, but it'll never last on that springer. Send it to me, I've got the perfect gun to attach it to. . . . . :lol:

I presume you didn't index those flutes by eye, nicely done! :wink:
