MARKII jamming

[Chopperdoc]

Have a problem I am hoping one of you guys and help me solve.
The gun is a Mark II frame with a ten inch fluted Tac Sol upper. Ruger stainless mark II bolt. With the factory upper it ran flawless. Since the TAC SOL upper was added it will get a fail to extract every so often. Maybe one round in five mags or so.
I figured a new extractor would help so I tried both the VQ Exact Edge Extractor and the Ron Power unit. Both have the same problem. When you close the bolt on a full magazine the round gets jammed, on an angle. It doesn’t even get in to the chamber.
I don’t know how an extractor could cause this but it didn’t do this with the factory extractor. I am about to call Ruger and have them send me one but I figured I’d ask here first.

Thoughts?

Thanks

what ammo are you using? hollow points will cause feed problems

Same ammo that ran before, CCI 40 grain plated round nose.

Problem went away after I installed a factory extractor that I had left over from another pistol.

Don't understand it but I ran a couple of mags thru it without any issues.

May want to look at your magazines. There is a mod to make the bullet release earlier, preventing jams. The mod is a simple rounding of the ears.
