Does anyone have any good pictures of sights for a parrott rifle? I have the AOP book with them in it, but the Stadia (round) style sight dosen't show how or where it is suposed to be mounted? The Stadia sight has the front sight mounted on the rim base. Also the AOP book dosen't show any front sights so pictures of those would be very healpfull.

Thanks for your help in this matter, Wes

I don't have the other information yet. The threaded part that the four bladed peep sight moves on has a thread pitch of 40, the same as a micrometer.

That is a four bladed peep site! I was having a ard time cyphering the plans. That page in the book was a bad copy.

Thanks for the photo, Wes

I don't know if your plans show it or not, but the knurled part next to the four bladed sight part is a jam nut that locks the bladed part in place after you make your adjustment. The advantage of this type of sight is that the rifling in the Parrott throws the projectile more and more to the right as the range increases. This way you can adjust the sight to compensate for the drift, something you can't do with a pendulum sight.

I thought rifling was suposed to make the boolet fly straight?

the rotation of the round will send it sideways after a long range. like a bowling ball that the lanes, travels sideways. i know ikonw rifling should make it fly strait but it is a slow rifling not a fast trist like modern gun. hell look at a russian mosin nagant that rifling is crazy i wish i could put it in a cannon.

The rifling is to stabelize the projectile making it more accurate. All guns with right hand rifling will throw the bullet (drift) to the the right Even in fast twist barrels. The latter US rifles all had sights wich rose at an angle to account for the drift starting with the 1884 Buffington rear sight, the 1902 kraig and the 03 seris.

According to Robert P. Parrott with an elevation of five degrees (2100-2200 yards) the round would drift four yards to the right. It would drift 10 yards at 10 degrees of elevation (3500-3800 yards). The lower distance is with shell and the other with solid shot. I assume the tests were with solid shot using a 100 pdr. Parrott.

Powder keg,
If you need help with the location of the mounting of the sight base let me know.I can supply you with dimensions. The photo Norm posted above is a sight I made.

I'll take your help Cannonsight. Thanks! I plan on building a sight for one of my Pack parrotts.

Sure thing. Drop me an email & I'll send you the drawing. For the pack Parrott I make a breech sight due the short sight radius and the timeframe that it was designed.-Fred

Thanks Fred! I sent you a PM with my Email at the bottom. Your Website button on your profile isn't working but I found it, Nice work and thank you very much for your offer to help. What do the breech sights locate on? The vent hole?

Later, Wes
