If so what were the results?
I am talking in a manner to shortening the stroke of an Uzi, with a buffer. On my Uzi I found, it of course speeds up the rate of fire, but that rate increase also smooths out the feel of the Uzi.

I was wondering if someone here has tried something similar on a 76...

I’ve stacked 2 buffers in mine but it my gun ain’t running 100% yet. I’ll report back, when I get some parts in mine and I’ll (hopefully) be able to say add more input then.

People have put a D-cell battery in a Swedish K to speed it up. I don’t know if the tube on an M76 is the same ID as a K though.

Never thought about speeding up my SW76, seem it has a nice rate of fire.
I have seen others with different MGs, lighten the bolts, use stronger recoil springs and like stated, stack buffers.
Not sure I would want to use a D cell battery. Maybe make a spacer out of aluminum. Good luck.

why speed it up? Are you just wanting a bullet hose? Slowing it down like a Swed K would be better (in my opinion). MK760 at 720 RPM vs Swed K at 550-600RPM. Most think hands down the slower rate is more controllable.

I added a couple pieces of old conveyor belt that i cut to fit the tube on my burgess 76, shortened the stroke about 3/4" went up to about 800 rpm which was noticeably faster, was pretty cool, took the pieces out and dont risk the gun "beating itself to death". standard ROF is fine, but yes its doable and yes it works.

I can certainly understand the urge to experiment. That said the S&W/MK series of guns tend to be problematic in terms of reliability. I would think speeding up the cyclic rate would only decrease the reliability. I think this gun needs time for the bolt to be blown back to let the expended round to leave the gun.
