Let me try to download the drawing one more time. If it does not work it is because I am trying to download Microsoft Publisher to the FTF. I am trying a JPeg on this one. We will see if it works?

Around 10 years ago I fired my Colt New Service. I never experienced 2 rounds going off in a revolver when only pulling the trigger once. What happened was the recoil plate(donut) had fallen out without my knowledge and I didn't notice it when I swung open the cylinder to load.

Apparently when that recoil plate is missing the gas blowing back when the primer ignites has enough force to send the hammer back again and then the hammer fell forward discharging the next round. At this time the firing pin embedded itself into the primer and it had to be freed in order to open the cylinder again. This scared the crap out of me.

I happened to have a recoil plate from a SAA that was slightly larger that had to be fitted. That little donut also had to be staked to prevent it from happening again. But other than that incident my 90 year old Colt never gave me a problem.

Since you said you own a DPMS, odds are it is NOT staked adequately.

I had the same problem with my rifle. I just used a dremel and cut it off. Just make sure that you don't go all the way through so that you don't damage the buffer tube and then use an ar tool to break it the rest of the way. You will need to buy a new castle nut of course but they're cheap. Took me less then 5 minutes to do the whole thing so it's pretty easy.

You can reuse the castle nut if it's not damaged. You don't stake the CN, it's the end plate that's staked and of course Ruger said he's replacing it.

Well when I did it the nut got cut in the process. Wasn't bad enough that it couldn't have been reused but looked bad enough that buying a less than $5 nut was a better choice.

Still, it doesn't mean that he will need a new castle nut if resonable care is taken.

Man I am telling you, it sure looks like it is. The gas key is tight, after 3000 rounds. I do keep an eye out for loose stuff, as I am a cleaning freak.

Got off work early today, and popped the castle nut off, and viola, I have a new end plate with a sling ring. Forgot about the spring in the buffer hold pin. It flew out, but with my quick eye I saw it hit the wall, and found it and the spring. Whew, that was a close one.
