OSU, Yea, it was worth a look.
https://matchgrademachine.com/product/build-a-custom-barrel/Checking out the MGM situation: You can go upto 13" barrel for $250 and get choice of almost any caliber
and barrel contour. It is a good deal given you can spec out exactly what is wanted. Longer barrel, more dollars.
That is a plain barrel, everything else is extra charge.
It can get a bit pricey when you figure good iron sights. Which I would like in some calibers such as rimfire. A weaver
style base is another $50 and should cover most applications.
On the extreme end you can push $700 for a 500 S&W class round with big bore muzzle brake and iron sights. (sights purchased and supplied by you) You can go higher with polished stainless. It all adds up fast.
The little extras you take for granted really run up the price on a custom.
