Daisy 880 Project

I’ve decided to go cheap and traditional with my latest airgun – a Daisy 880. One of the new ones, made from wonderful plastic. Daisy has been making the 880 and many variants since 1972. For many teens, this was their first air rifle. I guess I’m a late bloomer, as this is my first 880 I’ve ever owned.

The original air rifle had a metal receiver as did many of the .22 variants. Today, there are no .22 variants, and the metal receiver is now plastic. This comes as a disappointment to many, but there is still plenty of metal  where it counts, including the trigger.

I’m not going to test BBs in this rifle, as I want to keep the barrel intact for pellet shooting. Speaking of which, I tested many of the pellets I had on hand to set a benchmark prior to modifying the rifle:

Not too bad, definitely lower than the advertised velocity, as the lightest pellet didn’t touch 700 fps. We’re going to change that. First things first, though. It doesn’t matter how fast your air rifle shoots if you can’t hit your target. The Daisy 880 comes with a trigger creepier than that weird uncle you don’t want to be left alone with. While this will never be a match grade trigger, a bit of file and polishing work will make it a good hunting grade trigger. Take a look at this picture to see what’s involved:

To reduce the creep in the trigger to a minimum, grind down the nub on the trigger pointed out in the picture. Go a little at a time, keeping the angles square for a crisp release. Do not remove too much, as it will become unsafe.

Once you have the creep reduced, file smooth and polish the green areas. A set of needle files and sandpaper is all that is needed. This will smooth out the trigger.

To further reduce pull, I removed the flat spring found in the action block itself. For now, I’m going to leave the hammer spring alone. As I modify the pump and valve, the spring may end up getting replaced with a stronger one.

Lubricate all pivot points and reassemble. I’m very pleased with the results. In my next modification post, I’ll show how to tweak the pump for more power.

If you need some help in disassembly and reassembly of your 880, go to YouTube and check out the videos uploaded by user Joseph Lewis. I couldn’t do a better job explaining!

I've enjoyed shooting and hunting with airguns since my early teen years. For well over a decade, I have shared my passion for airguns on this website.
