NO! it's not good on the spring. Also NEVER dry fire an air rifle. It will ruin the chamber. When a pellet is fired the compressed air actually slows down the piston at the end of the cycle. If no pellet is in the chamber the piston slams against the tube and will eventually ruin it. If the spring is compressed too long it will loose all it strength over time so never leave it cocked.
When the rifle is cocked, a spring is compressed. Pulling the trigger releases the spring, which pushes a piston forward, The piston compresses air as it moves. The compressed air blows the BB or pellet out of the barrel.
The Underlever on an Air Rifle is a bar that runs just under the barrel and is hinged inside the stock. It is used to cock the spring in the rifle. Some air rifles use a sidelever but they also do the same thing as an underlever. The lever must be re-cocked after each shot.
Nitro has a few advantages over Spring. You can leave it cocked for a long period of time and not worry that it will loose it 's power. You have a more even release force with nitro ( A spring wobbles). There is not a spring to break or get soft over time. The power will always be consistent.
No. the Remington is a spring system air rifle. It requires that it only be cocked and then fired to work. No C02 is required.
They will last for years. If you take care of them. Never use regular oil on them, only use Crosman pellgun oil or RWS air gun oil to lubricate them. Never use regular gun cleaning agents on the rifle it will eat away the O-Rings. If it's a pellet gun / Rifle never force it to shoot BB's. Hard BB's will destroy the rifling in the barrel. Never leave it cocked over night, it will weaken the spring. Take care of it and it will list a lifetime.
Could be several different reasons. Are you using the same weight pellet. Different pellets create a slightly different sound. Also a new rifle has a break-in period, it takes about 100 to 200 shots for an air rifle to break in. The air chamber settles down over time. Or it could be just where you are standing. If you are close to a wall the sound bounces off the wall back to you. Also never dry-fire a pellet rifle this will damage the air cylinder and never leave an air rifle cocked for days on end, it will damage the spring.
First of all make sure it's empty and in SAFE Mode. If it's a springer and you leave it cocked the spring will loose it tension over time and not be effective. If it's a C02 then it will eventually leak and ruin the seals in the rifle. So never leave it loaded or cocked. I wipe mine down with a clean cloth. I only use Crosman pellgun oil to oil the joints. I use Cleaning pellets every 500 shots. They look like a pellet but are made out of Cotton. ( you fire them through the barrel.) You can find them on Pyramydair online. I take a soft rag and put a little Pellgun oil on it and wipe down the rifle if it's going to be stored for a long time. I have a rifle sock or rifle case that the rifle is stored in. Never use any firearms cleaning solutions on the rifle it will eat the seals and O-Rings. If there are children in the house put it where they can't get at it. Personally I have a rifle safe but I know most people don't have that option. Treat it like a firearm. Be safe and put a trigger lock on it.
A spring powered system uses a spring that is inside an air tube. The spring is attached to a piston. When the rifle is cocked the spring and piston are drawn back and locked at one end of the air tube. The other end of the air tube has a small hole that is directly behind the pellet and rifle barrel. When the trigger is pulled the spring is released and it pushes the piston down the air tube forcing all the air through the hole, and that fires the pellet down the barrel.
CZ air rifles have an automatic Safety. There is a pin at the rear of the barrel that must be pushed in before each shot. It will re-safety the next time the barrel is cocked.
It should stay cocked. The gun has problems. But, it's such a cheap pistol I wouldn't even try to fix it. Just buy a good C02 pistol, or something that will last you a long time.
An air RIFLE that shoots pellets through a rifled barrel will leave identifying marks on a fired pellet. A smoothbore air GUN that shoots BBs usually will not.
