any leads on an op rod for a G41??

If so I could use two or more
Thanks
Don

Theory always sounds perfect, but I am for trying the stuff. Although this is not the gun to modify and improve, I think such experiments worth to take place.

(Frankly, it sounds a bit like funemployment to us, but it takes all kinds to make a world). He has, in fact, already wrangled his first scratch-built metal part, a stainless-steel gas piston for a German G41(w) rifle, a rare and short-lived experimental weapon. The G41(w) was a milestone on the path to the much more successful and common G/K43 semiauto rifle. But rather than hear the story from us, get thee hence to a nunnery to GunLab and read it on his pages. […]

They serve to extract energy from the escaping gas and serve as a seal. That’s why hydraulic valve spools usually have similar grooves. A thread wouldn’t do as well since it would provide a continuous (though long)direct path for leakage.

My only ‘smithing experience comes from doing some careful tuning of my 1911’s, replacing the hammer components in a Ruger .45 Colt Single Action to get a more “Colt-like” function, and removing an internal lock from my .38 S&W 442 J Frame carry piece. All projects have worked out well; I took my time, used Jerry Kuhnhausen’s excellent Shop Manuals for the 1911 and S&W revolver. a good DVD for the Ruger work, and an excellent YouTube video for the internal safety removal. Also, and very important, a real set of gunsmithing screwdrivers!

You’re in my “gun and prep” folder of bookmarks now, and I’ll be checking in every few days to see progress. I’m currently active Army, on the MEB route, and once I’m done, I’ll be trying to use my GI Bill to either go to the CO school of trades or Murry state college for a gunsmithing program. Thanks for this interesting educational resource.

On a side note, is the commenter will cushman the gentleman who ran a gunsmithing blog a while back?

Re:the steels. Of course, metallurgy has evolved a good bit in the last 70 years. The metals used in WWII German weapons conformed to the then-current DIN norms and may or may not be a good match for today’s steels. In my experience with aluminum, there are alloys that are substitutable because they’re structurally similar, but they’re not the same.

Despite the evolution of metallurgy, plenty of metals and alloys that were useful many years ago are still useful and widely available.

Sure, it would be harder to make than simple grooves.
