Make a new one yourself, Brad, out of 4140 and heat treat it. Just heat red hot in pliers or in a thin
wire hook and drop into a tuna can of oil. It will be strong as heck, nicely blacked and you'll not have that problem
again. I have never seen one of the real Bo-Mars break anything, and there were dozens of them in my
club and I own a couple on 1911s that have shot in the 70-80K rds each, are fine. The various clones seem
to all have some issues. Cutting the notches on the outside will be a bit if a hassle, though.
An indexing head will move it, if you have one. then either just a couple passes with a file or find
a V type pointed mill cutter. The key design point is a good transition radius from the head to the
shank. If that is a sharp corner....the head will pop off.
What is the thread?
There is a Kimber clone, and a friend has had that break twice, sigh blade broke off of the
round part which slides laterally in the windage thread. There are a number of clones, hard to
know if they are all the same supplier. If you could find a real, old-stock Bo-Mar, grab it. They are
almost literally bullet proof. Certainly 1911 slide proof.
Al - I ran two Gold Cups in competition for a long time, many tens of thousands of rounds. Broke one
cross pin, replaced it with 1/16th piano wire with a slight bend to keep it from moving, no more problems.
And eventually broke the cross slide threaded adjuster. Got a new sight. As much grief as the
Elliason's get thrown at them, they really aren't that bad. Not 100% but not junk either. Pretty
durable for as small as they are.
