Reed,

Welcome, and thank you for posting; the information is interesting.

One design point catches my eye from a safety perspective.

From this photo of the bolt on the website, it looks like the extractor undercuts almost all of one lug, and there appears to be a hole drilled through the bolt for a pin or screw to hold the extractor in line with the lugs. This bolt design seems like weak from a safety perspective.

Any more information or explanation regarding this design?
