Hi I’m loe from Holland I have a new Chinese 880.
I love the dammned thing.
I did most of the improvements.
Filled the hole in the pumhead.
Removed the flat spring.
Filed some of the sear.
And polished it.
Did the trigger shim mod.
The new gun has a snug fit in the plastic sight in front so I didn’t have to do the barrel shim.
Filed the stock with silicone putty.
First I was shooting at 10 meters.
And it was verry presice.
Now I’m shooting at 18 meters, and come to the conclusion it becomes pellet picky.
Still trying to find the one s it’s like.
Important thing to keep your seals in good shape.
Store away with one or two pumps.
OK that’s it.
I’m waiting on a chrony so I can do some more modding.
Opening transfer port some more. If needed. And most important replace or grind the pellet probe.
It’s half a mm. 0.5 wider than my artemis pr900w probe.
So some improvement can be made there. Hopes. 😉
