You may be asking about a Daisy Model 1700 (Copy of a Glock) It was dark Grey in color and made between 1991-1996
Remove the grip on the left side of the pistol and insert a C02 bottle. Load BB's through the door at the rear of the pistol. Tip it forward and push the lever ( It's in front of the trigger) to allow the BB to load. Aim and fire
I would suggest contacting Daisy air gun directly through their Customer Service. See the link below
On the back of the pistol you will find a long lever, slide it to one side and load in your BBs. Under the barrel you will find a thumb loader to load each shot into the firing chamber between each shot.
No it's a spring piston system
I suggest you go to the Daisy web page and fill out the form to get the parts you need. See the link below.
The disposable aluminum CO2 cartridges used for airguns are standardised, and should be compatible.
I have researched this model and can not find any Daisy m2001 powerline. They did make a model 2003 that fired 35 rounds. it was made between 1995 and 2001. It was semi automatic. But it was a pistol not a rifle. If this is your pistol I suggest that you contact Daisy directly (800) 713-2479 and ask for an owners manual.
The earliest that I know of is the model 100 made in 1962
The BB magazine is on the top of the barrel. Put the gun on Safety, Slide the clip toward the front of the barrel, beyond the BB opening. drop in the BB's and let the slide push them together. Load the C02 cylinder into the left side of the grip under the let grip. Screw in the nut at the bottom. Aim the gun remove the safety and fire. The Daisy home page still had owners manual available for this model. All you have to do is download them.
Most daisy bb guns are made in China, with a few exceptions. Their Avanti line is built in Rogers, AR, and most of their CO2 pistols are made in Japan.
To propel BB's from their Crossman or Daisy CO2 powered air rifle. There is no method of drug delivery that used carbon dioxide cartridges. this guy chainsaw is a moron and knows nothing the guy is mistaking the nitro containers for whip cream and daisy bb gun cartridges
