I have an SA 1903 it is very clean and a well done sport model (not NRA)with peep sight on the back and blade in front. barrel is marked SA with a bomb and 2-20.
I am thinking of putting it back in mill spec. so the main thing is how hard is the rear sight collar to install?
Thanks
RJM
not that hard, if you have the tool i make that drives it on, without destroying the sight base,
a pin at the rear, and from right to left holds in place.
What is this tool, how dose it work, how do I get it, and how much dose it cost?
RJM
you can contact me via email, and ill be happy to fill you in.
I have one of Chuck's tools, and it is great! It is well worth the price, and simplifies an aggravating job.

I did one recently, and just wet or dry'd the inside of the collar so that it would slip on without too much force, and then soft soldered it into position, lining up the marks while she's hot. Can't see any visible solder, and even put the pin in.
base should not be heated, welded, glued or otherwise.
it is a press fit, on an orginal 03 barrel.
it simply presses on from the muzzle end, and held fast with 2 pins.
i dont recomend modification of an A3 barrel to fit the 03 sight base..
unless its done right it will have play, and will likely move.
if it had to be heated, or soldered, it wasnt done right..
Chuck,
Sending you a message regarding this issue with my rifle.

Another thing about '03 RSB's that nobody's mentioned is that you need to find the correct one. There appaers to be several types. O ne has the alignment pin on the left side, another has it on the right and the third is universal having pin holes on both sides. Just look at the knox form to see which side the pin slot is on. They are also found with or without lightening cuts. And last but not least measure the distance on your barrel from the shoulder to the cross pin slot. I have one i took off a scrap barrel for a restoration project that has the cross pin located 3/32'' further back towards the reciever. I've never seen another like it.
