Indians For Guns

I have a Precihole NX 100 that is about 4 - 5 years old now.

About a year back, I faced a strange problem with it. I ordered a pack of Precipell pellets. As far as I recall this was my first time using Precipell pellets.

Oddly enough, the pellets seemed slightly larger than the barrel of the gun. I had to push the pellet in with a pencil tip (with the lead broken off) to get it to fit inside the barrel. If I didn't do this, firing the gun had no effect on the pellet, it just stayed stuck in the barrel where it was originally placed. The pellet had to be manually pushed inside the barrel to get it to fire.

Same problem with pellets from another box (but still Precipell).

This has been continuing for over a year now. Today, because it rained (in January) and the weather got colder than usual, even pushing the pellet into the barrel seems to have no effect. The rifle has to be fired 2-4 times to eject the pellet.

Without being too knowledgeable on the topic, I naively think the iron barrel might have shrunk somewhat. Or, the Nitro piston is losing its power (unlikely to be to such a large extent). Or I have been unlucky in repeatedly receiving bad batched of pellets.

What do you guys think? And how should I fix this?

Nitro has given up long back.
Get a new one.

It seems unlikely to be the Nitro. Because after it shoots, the pellets go the usual distance. It is only getting the pellet into the barrel that seems to be the problem.

What in your experience is the approx expected life of the Nitro piston? In years or number of shots fired?

In the absense of adequate pressure the said AR unable to eject pellet.
It happens & can happen when pressure goes down.
Barrels have some tolerances.But it can not be so narrow that it can not eject pellets.
All nitro pistons lose power/pressure with the passage of time.
Nitros are tested to deliver 20000 shots yet I have not come across any single users comment that nitro piston maintained same pressure or power from 1st to 19999 shots.
Mostly it gives up much early.

It seems to be a problem with the seal. I spoke to the company people and they said the lip seal needs to be changed and I should send it in for servicing.

I am making a new post to ask whether changing the lip seal by myself (assuming I am reasonably handy with repairs) is a good idea.

Once company has digonised the disease then you buy lip seal and change on your own.Why take trouble to send it back to factory subsequent exp.too.
Here are lot of guideines as to how to change the seal.Follow that.

Thank you for the motivation.

Yes with the right tools you can change it yourself.
