Dear Group: I am new to the group and haven't researched the archives for this topic yet. Sorry if it is a repeat--I will look for it.
Could someone describe the procedure for removing and re-attaching the front sight?

Thanks, 57Fordman

If you want to re-use the sight, it should be removed with a special block and a puller. Similar to pulling a gear off a shaft. You need a special plug to protect the muzzle also. If it’s a one time operation, it would probably be cheaper to send to someone already equipped.

If it has a pin, knock it out with a rock and a punch. Then clamp the front sight in a vice and turn the barrel with a 14" pipe wrench while pulling the barrel out of the sight. Touch up the marks with black paint.

OR

...sent it to PK, he won't leave marks on the barrel

If things don't work out exactly as you wish....I have a spare M1A1 ring sight that I'd sell for ten bucks + shipping.

I've always found an oxygen / actylene torch works well, but makes a helluva mess...

Picked up an unused (no hole drilled for the sight pin) Thompson front sight. Inside of sight is threaded. Will easily screw on a WWII G.I. smooth barrel, which is threaded for a compensator. No manufacturer's code. What do I have? How would a thompsonsmith know if the sight he is about to remove is threaded sight or pressed on sight?

Hawksnest,

I had seen, at one time, the sight you describe advertised. I believe it to be an after market part and although I have looked, I have not been able to find one. I don’t know who made them or when and also don’t think they are common at all. I finally gave up and made one.

An experienced eye will easily determine if the sight is threaded or pressed.

There is not a single gunsmithing problem that can't be solved with the appropriate application of a Dremel tool, JB Weld, and a black permanent marker (or so I've heard). wink.gif

Naw, ya just cut the section of the receiver away that the barrel attaches to with a cut off wheel, put new barrel on, fill voids with JB Weld, grind excess with grinding wheel, color JB Weld with permanent marker. Good as new! wink.gif
