Photo of barrel mandrel and partially completed barrel:

So far, barrel diameter has been modified to a straight tube design, and the barrel hood and lower lugs have been reduced enough to allow complete assembly. It still needs work, and a lot of tests and measurements need to be made, but it cycles manually with no interference.
The color is due to Dicropan T-4 cold blue that I tested out on the straight portion.
