What’s the difference between the 584 vs 583 series?
The Mini gas system has a little bushing in it. Clamped between the barrel and gas block, guarantees positive alignment, and its internal diameter is in effect the actual gas port. I wonder if it could be replaced with one with a smaller hole, if, in fact, too much gas was acting on the slide.
That's exactly how I fixed my overgassed minis before they made their way out of my collection. The bushing kits were easy to find back then. The maker no longer mails them to Canadian addresses these day unfortunately.
First time with a 583 Mini-14 on the range yesterday, fed well with .223 Remington FMJ. Is it normal for spent brass to fly 30+ feet away?
edit: some online research later suggests the answer is yes! Looks like I'll be machining a new gas bushing.
