Some
interesting advices that I have read about Remington 552 Speedmaster:
For all of you who have had
problems with misfire and ejection on Remington 552…
First, if a gun shop tells you that there is no hope for this beautiful rifle go find a real gunsmith fast. You can still order all of the parts for this rifle, enough to do a complete rebuild. Now keep in mind that these guns will probably fire more rounds than even a military rifle. This will cause some anticipated wear on certain parts. First stage of fixing will be to file and adjust the wear parts…the next stage will be to replace. Here are the parts to keep an eye on.
1. The
hammer (part # 40) gets flared at the head. This is due to not having a last-shot-bolt-hold and results in a dry fire every 15 rounds. Fix this with a file to take the flare out.
2. The
side of the bolt (part # 5) has two slide tracks that can build up some small nicks. Again a fine file will smooth these out.
3. Check the
carrier (part # 10, that pops up the next round) if the edges are ragged, smooth them out with the fine file.
4. There is a steal removable rail (
ejector) in the receiver part of the barrel (part # 20). Again with your file make sure that the rail is smooth where the bolt travels and the ramp that hits the spent shell is not rounded. This could be a cheap fix by just replacing with a new one.
5. As stated in an earlier post, check the
firing pin (part # 27) for wear and straightness. It will move back and forth freely when working correctly.
6. Check the notches in the
sear (part # 67) to hammer (part # 40) contact for wear. Best fix is to replace both.
7. Keep an eye on the
extractor (part # 23) for wear or sticking… keep it clean. They don’t tend to wear so much on these rifles, but can be a cheap fix by replacing with a new one (don’t forget a new spring -parts # 25 and 26- as well).
8. If you have an older gun and your barrel is in good shape ordering replacements for all of these wear parts will put you back into a nice working 552.

Also check part #69,
Sear Spring, to be sure it is strong enough to reset the sear after the bolt cycles.
Does the hammer reset when you manually cycle the bolt S-L-O-W-L-Y ?
Does the hammer NOT reset when you manually cycle the bolt as fast as you can?
If the answers to these two questions are both true, it may indicate a problem with the sear "reset" spring.

Pay particular attention part #20 described above and clean it exceptionally well when you clean your gun. In particular, pick out the carbon that builds up in the notch.
You'll need a very fine pick (I ground down a small screwdriver for a pick.)
After 100 rounds or so, you Will see carbon in this notch, and on the rails, and it WILL cause problems with cycling. Using DriLube sparingly helps ease the pain. Here you can see carbon on the rails after just 30 rounds:

To fix in a proper manner the barrel to the receiver improving accuracy in our Remington 552 Speedmaster, we have to buy and install a simple
receiver bushing (in Remington Parts cost $3.20, it is a part number #F16160 or V-50 in the part list numbers).
