Have either your local Stihl shop id it or put up a few pics and someone here will give you the correct part number to use for reference.

The 52mm OEM #1115 030 2001 is a domed (barely) piston, and I recommend going back with OEM.

If you put a flat top aftermarket AM piston in it, the compression will be lowered, and so will the power.
There's four or five different 52mm AM ones that I have seen, one of them even has a windowed design like yours.

Post a picture of the flat tops you found...

Definitely a flat top you show there, & no I wouldn't run it because of the compression loss.

Like I said keep looking for an OEM, post a "want to buy" thread on the Tradin' Post under the Equipment Forums.

There's a lot of parts hoarders or "whoreders" that read those....

I was thinking the same about the the compression value with the dome would be lot better thanks hotshot
