It may jam the barrel or it may fall out but either way it's not the smartest thing to try. (NOT RECOMMENDED)
The 880 has an 11 mm dovetail mount. This BB/pellet rifle is fairly inexpensive and it works fine with a simple 4x10 scope, to put a more powerful scope would cost more than the rifle's base price. Daisy makes a 4x10 scope that works fine with this rifle
Your question is unclear.. but i will do my best to answer you the best possible. There are two possible interpretations of what i THINK your asking me."Can you pump a Daisy Powerline 880 40 times?"or"Should you pump a Daisy Powerline 880 40 times?"Yes, you CAN pump it 40 times... but it causes severe internal damage to the gun's firing mechanism. It can cause the gun to malfunction and not work properly.
It may work but it is not normally recommended because the shock from a pellet rifle is different from a regular firearm and it been known to jar loose the glass in a rimfire scope mounted on a pellet rifle.
No- and it would be very dangerous to try. Pellet guns and airsoft are two very different things.
They work any where there is a powerline. So they can work on the utility poles in your neighborhood, in the sewers of cities, or in the tall towers going across the less populated areas.
I understand it is one of the hardest models to work on. I suggest you contact Daisy at the link below and ask for a diagram if they have one.
the rifle has a dovetail mount for a scope built into the design.
All pellet guns use compressed air or gas. 1. Spring piston: Cocking the barrel of the rifle compresses the spring and piston inside the rifle or gun that is located in an air cylinder. When you pull the trigger it releases the spring and as the spring shoots forward, it pushes compressed air ahead if it that forces the pellet out the barrel. 2. Co2: A Co2 bottle it inserted into the gun or rifle, and it is full of compressed Co2. When you pull the trigger a burst of Co2 gas is released and the gas pushes the pellet out the barrel. This same idea is used for the larger PCP rifles only they use a much higher pressure bottle. 3. Pump: When you pump the forearm of the rifle it stores air in an air chamber. When you pull the trigger all the air is released behind the pellet forcing it out the barrel. BB guns work the same way.
This is a Daisy Model 1894 made for Sears. I understand it is one of the hardest models to work on. I suggest you contact Daisy customer service at the link below and ask for a diagram if they have one.
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.
If you are asking how much is it worth? Then in order for me to answer you I need to know what physical condition it is in and is it still working. All this determines the current value. Rate it something like Poor, Fair, Good, Very good or Excellent. Then I will have something to work with. Or you can contact "Daisy" directly and ask them. They offer a free service to evaluate the value of older Daisy air rifles and it's free. See the link below for Daisy
