O. Schaefer from Sweden emailed me the pictures below of his newest airgun build.
Barrel is an ex Diana 35 barrel, .177cal. 470mm in length. 3000psi fill pressure, 280cc
of air. Stock made from glued together sheets of plywood. Total length of gun;
610mm. The mechanism is very much based on ideas from Mr. H.M. Buckley.
O. Schaefer has posted some video on his bullpup. Here are the two videos that I know of.
