I have a new Kreiger med wgt stainless barrel (short chambered) that I have bought to go into new JRA Receiver. I'm not trying to install it myself but I was test fitting some parts more for my own knowledge than anything else.

When I screw in the barrel till hand tight,it stops short of timing by 30 to 35 degrees.

1) Does the wrench pull it up (seems like a long way still to go)?
2) Is material machined from the receiver face?
3) Is the barrel machined back a little furthur on the face contacting the front of the receiver?

I assume the short chambering gives the clearance for some type of machining operation to complete the barrel timing.

Thanks

James

Yes it will time with tightening without turning the barrel. The chamber will then be reamed to proper head space after the barrel is installed.

You might need to turn the shoulder of the barrel a few thousandths as pre-150 JRA threads were off by 10 degrees. This was fixed at 151+. Rule of thumb is if you have modify a part to fit, modify the cheapest part, thus the barrel and not the receiver. Post some pics once you have it assembled.
