Not being able to find the high arms for my chamber has driven me to do the TDC mod.

Has anyone done this to a PDI chamber? I wouldn't think it would be any different, except as you may know the PDI chamber has two arms.

Going back to stock chamber is not an option. Unless it's extremely recommended. I no longer have my stock chamber. Only crappy part is that I would have to buy the chamber, new barrel and bucking :/.

Just looking for a procedure.

Also, what I like about the PDI chamber is the ability to adjust left or right. Would it be possible to do the TDC mod and still retain this feature? Maybe use a smaller screw or grub screw in diameter for each arm? Or is this going to be too much work? I'm thinking I'd would either have to use very small screws or I'd have to make it so the screws came into contact with the arms at a slight angle so I was sure I had space for them on the outer barrel.

Thanks,

Shane

And those are 100% for sure for the VSR/BAR PDI chamber? The last set I bought was for the wrong gun....

Call them. they sell the chamber as well and the mechanic there has a great rep. I'd call them if you had questions before ordering

Read through the TDC guide in my sig and stickied in the general section. It's in the comments how to TDC the pdi chamber.
