I bought a Remington 783, chambered in 308 approximately 6 years ago. I’ve had the same issue with the bolt multiple times. When shooting factory loads, essentially the extractor detent ball for lack of better terms “explodes” causing small amounts of powder like shrapnel to hit me and then it obviously won’t eject the spent cartridge. It’s been sent in for warranty multiple times for the same issue. My question is does anyone have leads on aftermarket bolts, better parts to rebuild the bolt head myself, or even OEM bolts? I’ve tried to look myself and haven’t come up with much of anything so I’m expanding and asking others, I appreciate any knowledge or info the community has.
