Martini Henry rifle clamp-on front sight holder w/ adjustable front sight inserts

thingiverse

My Martini Henry shoots way high and a little to the left at 100 metres/yards, so I designed this front sight post that clamps on the barrel and slips over the existing front sight. You will need two M3x12 screws and two M3 nuts, the holder just slips on and is then clamped in place, with no damage to the finish or any modification to your valuable antique firearm. It is designed around the front sight of my MkIV pattern A type rifle, so may not fit yours or require some modification after printing, Front sight inserts are dovetailed for windage adjustment and are available in heights from 2.6mm to 5.0mm in 0.2mm increments to account for different elevation settings. I printed mine in PETG and had no issues with temperature stability even after 30 shot strings. I have also attached a muzzle protector that slips over your cleaning rod and barrel to protect your muzzle from damage when inserting the jag and rod.
