Lothar Walther ready to go for the AR/QBD

My intention is just to machine off the forward part of the bolt, drill and tap it, and make a larger front section carrying a larger O-ring and pellet probe....

Bob

Would you post a pictorial of how to do the probe, please Bob?

[rsterne]

Will do when I machine the bolt....

I also was thinking of making the pellet tray separate from the barrel.... I presume that is what you did?....

Bob

[Gippeto]

You got it Bob. :)

One modern adaption of the multi-screw breech is a British airgun (can't remember which one, but I saw a video) that uses 6 setscrews arranged in two groups of three, front and back.... Each group is at 120 degrees (one on top, others on lower sides, IIRC), allowing the barrel to be "steered" to align with the optical zero of the scope (at your intended zero).... Obviously the breech fit is intentionally SLOPPY to allow for that.... Apparently it works extremely well....
