My model 6660 (same as model 60) will not feed. It's the old style with the split feed ramp. I would like to update it to the newest version feed ramp and spring ejector but can't find the kit anywhere. I guess I could buy a whole action assembly on eBay but I'd rather just buy the update kit with the feed ramp, lifter and spring. Anyone know where I can find that kit? I've tried Brownells, Numrich, Midway, and McCarbo. No luck.
