Hey Mikepsu. The only adjustment options you have with my LOL Sight are (1) changing the front sight height to move the point of impact up or down, and (2) making an extra rear sight "nut" with the mounting hole drilled a little off center to adjust windage. That's OK for my purposes with the Zouave. I'll be shooting only patched round balls with one load of powder (still working on the most accurate load). Once I decide what load I'll be shooting I'll fix the sight to match that loadfor dead on at 100 yards,and stick with the selected load. One option for windage would be to weld or solder the "nut" to a dovetail base that could be drifted right or left.

I have a newGreat Plains .54 flintlock that I haven't even shot yet (Merry Christmas To Me). I'm modifying the adjustable rear sight in somewhat the same way as the Zouave sight, but it will be a lot more streamlined and will be able to use the elevation adjustment feature of the factory sight. I'm replacing the sight notch part of the factory sightwith a 3/8" modified nut that will take three different apertures. I'll post results when I've got it done, and have had a chance to try it out. That won't likely be until after hunting season (ends 28 Jan 08).

The big difference between my set-up and a true aperture sight is that mine is located forward on the barrel where a regular iron sight would be, whereas a true aperture sight is typically mounted on the tang close to the eye. I'm sure mine loses something with respect to accuracy potential. But, for a muzzle loader, I like its looks.

Try this to see if you like it. Take a 1/2" by 3" piece of cardboard and punch a 1/4" hole near one end. Bend in into an "L" and tape it to your barrel near the iron sight so that the hole is just above the sight. Shoulder the gun andtake a sight picture through it. If your eyes are like mine, you will be able to see the front sight much better, and will automatically center the top of the front sight in the hole. Take it outside at dusk and take a sight picture on something fifty yards away - then rip it off and do the same with your regular sight. You'll be surprised at the difference.
