| Brent,
What Dan mentioned about the mouthpiece and receiver is true. It would be best if you sent your mouthpiece to Roy, should you decide to order an LF-1, so that it could be custom fit to the receiver.
As to the bore-size question... please hold that thought... Roy is in the process of re-working the design, from that perspective. We will keep everyone posted, as soon as all of that has been worked out. *Note... the changes will not be huge. :wink:
Best always,
Bruce |
