Inland, think it's been rebarreled, the crown has no finish to it...I replaced the wooden stock with a Ramline a long time ago to give it that evil black rifle look...
Loaded up all my 15 and 30 rd mags about 20 in all and spent 2.5 hours cleaning it real good. Got as much of the carbon as humanly possible off the gas piston, made the gas port wasn't clogged, and went to the range. The mags were loaded with Winchester Q3132 factory ammo.
First range session I went through about 1/2 the mags, every 3rd mag I'd get a failure to feed, a round would be 1/2 in the chamber and 1/2 in the mag. Figured I have weak mag springs or something.
Today about 3 weeks later, went through another 10 mags, every one had a jam, especially the 30 rd mags, I'd have multiple failures to feed. Once a round actually got chambered it would extracted ok, but the next round wouldn't chamber. I even wiped down the feed ramp a couple of times, didn't seem to help much.
I'm about ready to give up on this gun, it's causing more agravaation than enjoyment.
Any ideas of how to make this gun enjoyable again?
