I picked up this little baby for $20 on Craigslist today. I have NO idea what it is other than it is cheap, and chinese. The only markings I can find on it are "Made in China" and 'R' on the compression chamber. It has a barrel lockup lever, a direct sear trigger, hooded front sight, elevation adjustable rear sight, 0.22 cal. Anyone have a guess?

It has a few issues that need to be sorted, the first of which is a wobbly front sight. Any thought on how to correct that? JBWeld? Gorilla Glue? I would prefer something less ugly, but if that is what I have to do, it's not like it cost me much.

I assume this has a leather piston seal. Can I use my 30W non-detergent oil for that, or do I need to get some synthetic stuff? Also, I think it has a leather breech seal as well. And it looks ROUGH. Any chance I will be able to replace it with an oring?

I took one shot with it from about 10 ft. just to see if it would shoot at all. It SPRAYED brown gunk all over my target paper. So, I am guessing I am gonna need to tear it down and clean it up a bit. It smelled like fried food after the shot, that good old chinese grease smell. Now I guess I need to figure out how to get the thing apart.

Shoot it some before doing anything to it, if it spit brown oil then it's still lubed from the factory. Non Deterg oil will work for lube, add a drop to the breech seal and let it soak in then wipe excess off. You can make a new breech seal from plastic tubing but if the oe is working I'd leave it alone.

I have this exact model. Not overly powerful, but pretty accurate at 25 yds. and capable of knocking sparrows and grackles off the bird feeder. Trigger on mine is very smooth and consistent. For $15 at a yard sale, I couldn't resist.

Thanks Mike. I should have known you would pop in with some input. Should I clean the barrel with a brush and patches, or just shoot it clean?

Any suggestions on shimming the front sight? I plan on popping it out to see if the dovetail is in good shape, and I heard some people shim it with aluminum. I'm not sure it has THAT much play. Should I try to break it in before I mess with the sights? Obviously it will bother my aim point a bit, but I'm not expecting 0.5" groups anyway.

Remove the front sight, use a centerpunch, and make several punch marks on the bottom flat of the dovetail notch. It'll tighten right up and still not be too tight to move as needed. I've used this method on PB's many times with good results.

20 strokes and then patches until they come out dry and clean or dry and grey...

except mine has a pressed on hooded front sight and a click adj rear disk for ele. When I received it a couple of years ago, the trigger was so heavy that when I fired the rifle it pulled way off target. So, I took it apart to see what I could do to make it better. I put in a new leather seal, cleaned the piston,whipped out the cylinder smoothed out the sear engagement points.Molyed and lubed where needed and used graphite on the trigger. Adjusted the barrel lock and breech block and low and behold....it is one of my favorite rifles! It is a .22 cal and it hits as hard as my .22 QB-78 (high 500's with Crosman field points)I can keep a .5 in c-t-c at 15 yards with open sights all day long. It has well over 1000 rounds through it and has smoothed out nicely. Get a QS-2 rebuild kit and turn it into a shooter!

Do I need to get a brass punch to remove the front sight, or should I use a wood dowel or something else soft? I assume I don't want to use a carbon-steel punch (which are what I have).
