MK 760 EXTRACTORS
I'm not opposed to making extractors specifically for the MK760 but I think that @RevolverJockey was offering to help with that one.
Personally (if I were to take on the project), I'd need access to one of these MK760s so I could reverse engineer and test fire. I'd insist on shooting at least a thousand rounds before I was ready to present anything to our community but the price of ammo is a financial hurdle these days too.
If someone here is willing, I recommend that an individual starts a separate post to see if we could gain enough support to justify the project. Please note that this is a labor of love for me and that I get really excited doing this but it's definitely not a real money maker either so I'd only take on the project if it helped a lot of people.
S&W 76 EXTRACTORS
Since I've already done so much work, I would very much appreciate it if the community would get together and coordinate a group-buy for one big order of S&W 76 extractors. Approximately 30 people bought a total of 50 extractors so far and I have to believe that there must be at least a few hundred guys with this particular sub-gun who still need these things. I'm not going to have the ability to do this forever so if there is a need than let's sort it now. Thank you, Sturmgewehr friends & family!
