Sticky bolt action on Marauder

Hi, guys. I have a 2nd gen Marauder .22 cal. that functions very well and has great accuracy with the right pellet. My brother was so impressed that he purchased one for himself. The PROBLEM is that my brother is crazy unlucky in just about everything he does, so he ended up with a lemon. I've tried 20 different pellets with varying degrees of poor accuracy. The best group I could achieve was about a 2 inch group at 35 yards. Mine makes a ragged hole at that distance. Anyway, that is a different thread. The other problem that I really need help with is that the gun is so darn hard to cock. The bolt action is super sticky and sometimes I can't even work it. I have to yank it back with all of my strength to get it to set. Sometimes its easier than other times. Mine is smooth and easy. I tried greasing the bolt but to no avail. I tried adjusting the hammer spring tension with maybe a little success, but its still a bugger. Any help? Thanks!
 
+1!
That's definitely what I'd do. There's things you can do to fix it like cleaning up the stamped out openings in the air tube then honing and polishing it's insides but if it's a new gun, send it back! I agree that Crosman IS excellent about replacing a defective gun. Been there done that and had a new rifle in a week's time. If you do send it back politely ask for something to compensate you for the hassle & shipping charges. They included a couple tins of their copper pellets when they sent the new rifle back. Good luck!

"Check the cap screw that cocks the hammer to see if it has backed out. It is visible in the slot on the left side of the action when the bolt handle is down. It sounds like that’s what has happened. Apply a drop of blue loctite to the thread and snug the cap screw up. That should fix it."

Someone correct me if I'm wrong but I believe ONLY the Gen1 marauder has the lug sticking out the side, on Gen2 it is not visible and under the receiver and always for sitching from left to right side cocking, my 1720T was like that.
Just so a newbie who might come along knows they are different.
Crosman's warranty is rock solid ( and transferable , at least when I called to buy parts for a used one- told them I purchased used- and they asked for the serial number and just said "we'll replace the rifle" ).

IF you don't care/want warranty de-gas it pop the receiver off ( easy ! ) and have a looksee. Something is:
binding
or out of place
slots on cocking slot rough - you should feel this ? -
But you also say groups poorly!
Bent pellet probe & just not sealing or shoving pellets in a bit sideways?

if new or under 1 year I'd likely send that one back even though I can rebuild one.

And come back & keep us posted.

I called Crossman Support and they suggested dry graphite lube (a powdery pencil dust substance, *don't inhale any or get in your eyes) for a similar problem I was having with my PCPs. It worked very well for me.

After wiping the parts involved with a clean rag and q-tips, I puffed a bit of the stuff on all sliding parts of the action and worked it several times and puffed at the parts I felt seemed to be sticking as I saw fit. It really didn't take much, so this small tube should last a very long time.

Bonus tip- The graphite can be messy, you may wish to do this on top of old newspaper and clean the whole thing up before throwing away everything all at once. Also you may wish to discharge air to puff any dust in an intentional direction before bringing it up to your face.

You also may want to check to see if the screw on the rail underneath the rear sight that is intergrated with the bolt action isn't over tightened...

 
I don't know what your mechanical abilities are so forgive me if this seems an obvious question.

On the top of the breech block at the back, there is a slotted screw there. That is not meant to be tight. Just try giving that screw a 1/4 turn out and see if that loosens things up. It should.
Otherwise, there are a couple things it could be. But with a new gun, I would send it back.
