Hi ,

I am recently moved Ontario, Richmond Hill city from India and i bought a very beautiful air rifle with which is a Nitro piston type rifle, i have been using it from lass 1 and half years and i really love the accuracy of the rifle.

Few days ago i was plinking with my rifle and suddenly got a call from my boss, i kept talking to him over the phone, in the mean while i packed my rifle inside the rifle case and put it in the closet. After about 3-4 days i reached out to my rifle for doing some target shooting which i usually do in every week i discovered that i had cocked my rifle in my last use and forgot to unload it the rifle stood cocked for around 100 + hours by that time, i tried to put a pellet inside the barrel and fire the air gun fired but the pellet didn't came out since then i have been trying have removed the pellet and tried firing the air rifle problem stayed same every time i cock the rifle and try to fire the pellets gets stuck, maybe be because of the low pressure or some thing i don't know.
Can anyone let me know which nitro piston to put as the replacement to that rifle to solve the issue i am attaching some reference image and model of the air gun india i bought here to for your ease kindly let me know where can i buy the piston or any air gun repair shop nearby me who is capable to fix it.

I know i can go buy some other air rifle which i will surly do in the future but i really don't want to let go of this air rifle since it was given to me by my father.

First off , welcome to the CAF . Next up , are there any pellets stuck in the barrel ? Last but not least ,that rifle appears to be a B18 clone of sorts . But the best way to get you the correct information would be to have measurements of the existing cylinder . If I were to take a guess I would say the gas ram from a Benjamin trail np ( first version) would fit . If you can please post some pics of the rifle with the stock removed .

My thoughts are the same.....if it was already cocked then it may have had a pellet in it. When you put the next pellet in it this would cause a jam. If you dont have a push rod pick one up, you will need it. Wooden dowel will work in a pinch.

Hi

Yes it is true 2 pellets got stuck inside because of my negligence i have removed them but now the piston is not performing well and not providing required power. So i think i still need to replace the piston, currently i am in a business trip to US but i had made a contact with a local gun smith in my area he said he will fix it by replacing it with other piston of the same size, i am goin to take my rifle to him in the coming week hope it gets fixed.

By the way i am attaching some images of the piston after disassembling the rifle i have measured the piston diameter which is 27.7mm,
i hope if you geeks can figure out a similar piston of the same size.
