New Benjy Summit Issues

[Hercule]

Got my Summit on 24th, put about 450 rounds through it. After playing with it for awhile, I noticed that when I broke the barrel down, and halfway through the pull, I felt like therr was dirt inside. There's that feeling you get when you have little dirt inside a wheel, or anything that turns. I got that, and after lubing the areas where the break barell rotates on, I still had that problem. Any way to take that sucker apart and clean ? Any advice ? I am very careful with it so I never put it in dirt, but there is something in there. Any help, or ideas as to what that might be would be great.

P.S.
Love the gun, it's my first air gun ever.

First just take the stock off. It may just be the cocking linkage inside has some debri. Try cleaning and lubing that but use the appropriate lube. If that doesnt help. Check the gun over a chrony to see your fps are in the right ballpark. You may have a broken spring. Unless it is a nitro piston then disregard. 

edit: sorry just looked it up. It is a NP. I would still take the stock off and lube the linkage.

Agree with crittahitta. Taking the stock off is a simple 3-screw removal. Nothing is exposed that will snap, sproing, or otherwise jump out at you. The cocking linkage is the long arm assembly that runs from the front of the air chamber (where the barrel hinge is located) back to the trigger assembly. You'll see that the linkage is in two main parts with a pin holding the two parts together about midway along the bottom of the air chamber - half way between the trigger assembly and the barrel hinge. Check this whole arm assembly out for any grit, debris, or rough bits that may be scraping along as you cock the gun. DON'T TRY COCKING THIS GUN WITHOUT THE STOCK ON! You won't necessarily break anything by trying to cock it this way but it is a total pain to do, and very unstable in the process. My Benji Summit (same as your rifle) cocks very smooth so I suspect it is a debris problem. Just be patient and use a good light to study the whole linkage. Having a thin probe or long, thin hex wrench might be useful if you need to tease a bit of loose junk out of the cocking path. When you put the stock back on be VERY, VERY careful not to cross-thread your stock screws on each side of the stock up toward the barrel hinge. Those screws go in at an angle and should screw in pretty smooth - any substantial resistance early in the seating process means you've not got the threads aligned improperly so back out the screw and try again! Ask me how I know this...

You said the assembly was the Front of the plastic area under the barrel, to the trigger assembly. I didn't know that was the stock and instinctively took the rubber padding out from the pack. This mean the threw screws are the two on the side, and the one on the trigger guard correct ? After that do I remove the whole bottom of the gun ?

There is 2 in the front (1 on each side) and 1 in the front trigger guard.

Update -- Took it apart like you told me and everything was clear nothing blocking anything. Still when I cocked it, I noticed a sound change (more rough) half way through my pull. Checked again, and nothing. I have no idea why this is happening as it did not happen when it was still new.
