New mark 3 jams every few rounds..wtf?
 

Every few rounds the brand new gun jams, what is it the mag ammunition or gun?? New to firearms btw

Probably ammo. What ammo are you shootin through it?

Remington .22 lr that's all I know it is.....................zz

Get some CCI Mini-Mags. That gun is to good to be running Remington crap through.

Aaaaaand there's your problem. Remington can be good in certain guns, but is generally hit and miss.

Try Mini-Mags, or Fiocci ammo.

Try different ammo. Also you said your new to guns, did you clean it before use? Often companies put extra grease on new guns and this can cause jams if not cleaned.
If after cleaning and ammo switch there are still problems contact ruger. They have great CS.

Just cleaned it and ill be sure and use different ammo next time around, thanks guys!

My 22/45 will jam frequently when I use Winchester bulk. It does much better with Remington, but have had a couple of FTE's with that.
Some guns are just picky about what they are fed.

My local gun shop recomended CCI mini mags, so I got 300 rounds and will be trying them next.

The first cleaning from the factory is a must. But I don't clean my MK II often, it seems to like that.
