YouTube gun design entrepreneur and kluger Royal Nonesuch is at it again, this time with a bolt-action shotgun. Claimed to be 90% complete, it features parts from a variety of sources. Mr. Nonesuch uses an HK lower receiver and parts group, Saiga magazine, AK-47 under-folder, and an AR-15 stock riser used as a fore-end.
Kudos on the engineering. With this kind of creativity, I forsee many creative and equally crazy designs in his future.
