    What to do with an MM ACII

    I have a nice little martini metford artillery carbine, nice except for its chamber is a trifle loose so hot or normal loads back out and jam the block, and itís foresight blade is mostly missing. Additionally it has a rather tight bore and groups surprisingly well....

    How would one go about replacing a foresight blade?

    Any thoughts on the chamber, it is fine with black powder but typically gets sticky with anything over a minimum load of smokeless, commercial ppu had it home in a vice being tapped open. It is marked D.P. I am guessing on the strength of its chamber, which Iíd say someone tried to polish some pitting out of.

    hi how does the brass go with just neck sizing after the first firing,another option is to set the barrel back one thread i had a smle years ago that was hell on brass set the barrel back one thread and did not have to put a reamer near it fixed all problems.
    i am all for preserving all these old firearms but when some of these oldys come your way that have had a butchering a little bit of tweaking can get them working again

    The shoulders move up quite a tad, and the brass is rather closer to a cylinder than the day one taper, but neck sized it is fine. The major issue is lack of a foresight. Has any one done any successful replacements on these?

    The sights are normally soldered on. A little heat applied with a propane torch will allow the old sight to be removed. Then buy or make a new one. Tin the bottom of the sight. Hold it in place with a metal clamp and apply heat. I did this to a swiss vetterli with a cut down barrel. I made the blade tall so I can file it to the height I need.

    I think that you will need a bit more heat than a propane torch. The front sight ramps are usually braised onto the barrel.

    The ramp will be sitting on a small flat cut into the barrel top surface.

    To replicate the original front sight you would need to be handy with a drill press or milling machine. But not difficult to make up a simple ramp with a flat base out of solid at the bench with hand tools. File up a bead or barley corn.

    One could even get clever and file a little dovetail to allow a driftable insert to be fitted. Soft solder the ramp into place on the flat with your propane torch.

    Not original spec, I know. But this one is adjusted to the Point of Aim. It is a touch taller than standard.

  10. Thank You to englishman_ca For This Useful Post:

    Ok, slap me down for blasphemy if you wish, but what are thought on gutting a dovetail into the existing block to accept a Lee Enfield for sight? And if so any one know the correct hight above centre of bore (or better still barrel outer surface) for the top of the foresight point?
