I am looking for a list of accessories that are best in class that are machined regardless of materials.
Some things that come to mind are the Gadget, scope mounts, speed loaders, sling mounts, accessory rail mounts items from the ongoing Beretta 1301 thread Red dot mounting systems for pistols, etc etc. I am sure there are others I am missing but will come to mind as you read this thread.
Thanks in advance for your input. You are doing a solid for a really great guy.
ETA: Ok guys thanks for input so far and just to clarify this guy is a master level machinist/tool and die/ machine design. with his nose heavily into engineering. He is a Vet with a record of service and schools that anyone would be proud of . He is heavily into PPC air guns and long range shooting. He already has a slew of prototypes for the PPC group and is getting ready to purchase some machinery doing prototyping and some production level work. He is NOT looking to copy other people's work.
I'm just trying to find some innovative top shelf products as a means of helping him expand his horizons.
