I was gifted a Remington model 552 and was told Its your's
See if you can fix it!
That was back in the spring of 2016 that The Jam-o-matic came into my life.
I knew the fellow that brought the gun over, a local gun tinker and gun trader (think horse trader) it seems this particular .22 had spent most of its life Out at Camp (I live on the Arctic Coast part of NW Alaska)
So he got the .22 in trade and refinished it with plans to sell it for a profit.
Except the Devil Gun had other plans.
I loaded it and tried shooting it.
It jammed, it failed to fire cartridges, and some times itd fire the odd shot.
Lots of On-line suggestions.
Gun-scrubber, burrs,different ammo.
It kept jamming and intermittantly firing.
I had live rounds with 3 light fireing pin strikes, fired cases with a single deep firing pin impression.
The first time I cleaned it, it was really clean inside.
Just some powder residue and some greenish metallic crumbies from Remington Golden Bullet.
I looked for burrs and gounf plenty, especially along the ejector grooves on the Left side of the Bolt.
Still it jamms and intermitrantly fires, Id load the mag full and it might fire the first round or not with lots of double feed jams.then I noticed a part was missing off the Disconnector arm, some time before Id gotten it the arm had broke,the nose part removed!
Do ordered a new disconnector arm, more Google time of Remington 552 troubles, 6-7 Youtube videos, a vouple different fourms.
After the disconnector was replaced, I foolishly thought it was fixed, it fired the first test shot just fine, then click, checked to find an empty chamber,
at that outing it fired 6 times just like a semiautomatic should.
After a couple years and little attention I started looking again at this rifle.
And replaced the magazine spring (old spring was 14" shorter than the new) and replaced the bolt return spring (old was 3" longer than the new)
Thinking a longer return spring and weak magazine spring were issues, I tested it again.
The Devil Gun fired the first shot, second was a dry click, then a jam as a fresh round was trying to load (double feed)
Out of the whole magazine 2/3 the rounds had a slightly off firing pin mark that was debaitable as having struck hard enough to fire the cartridge.
It looked like the firing pin was striking more of the center of the cartridge than solidly striking the rim.
After looking at the cartridges I thought it might be a good Idea to check the bolt and firing pin.
I found the fireing pin was Bent!
I need to order a new one.
I did try to straighten the old one using a flat metal plate to straighten out that wierd sprew shaped bend in the firing pin (Google image search of Remington 552 firing pin) was a Big help.
