Ive spent countless hours reading on the fixes.
Mark IV Hunter is 2 weeks old.
1st range trip using federal automatch 200 rounds fired, multiple stovepipes every mag.
bought Valquartsen extractor and firing pin.
installed
2nd range trip using Minimags. Only about 6 stovepipes in 300 rounds. Thought I had it mostly worked out
3rd range trip tried Blazers, minimags, cci std velocity, norma tac-22, and Federal automatch
Over 300 rounds fired. Stovepipes are back.
minimags did the best(stovepipe about 1 each mag) but all others did it multiple times each mag.
pistol has been cleaned after each range trip.
after all the reading I’ve done it seems tuning the mags would be next(or send it to Ruger)?
most of what I have read on tuning the mags is due to FTF, i haven't had any issues feeding.
today after I got home I was manually cycling rounds and it appears the spent case is hitting the front of the rear feed-lips, knocking it off the extractor early, causing the jam/stovepipe.
ive seen info on adjusting the spacing of the feed-lips and on rounding the front of the rear feed-lips.
Im hesitant to remove any material from the magazines. It seems that if I adjusted the space between the feed-lips outward that would potentially let the spent case not hit the magazine.
But would adjusting the feed lips cause feeding issues? Im not having feed issues now.
also something else I noticed; the mag release assist at the bottom of the mag well pushes on the back of the magazine, tilting the mag forward toward the feedramp. Should I remove the spring loaded assist?
also thinking I should remove the mag release and check for any irregularities.
another note, the ejector appears to be in the right position, its riding the center of the bolt and almost hitting the bottom of the bolt.
one last thing, does this Valquartsen extractor appear to be shaped properly?
