Hammerli parts

1. Does the Trailside/Xesse magazines fit the Hammerli 208/215 ?
2. Are the fire-pins inter-changeable?
3. Does the Trailside/Xesse plastic magazine follower fit the 208/215's magazine?
4. I guess the scope mount for 208 will fit the  215?

From looking at the parts on Red Feather, I would say:
no
no
no
maybe  Saw one for sale and only listed as 208.208s
But feel free to correct me!

4. Depends on scope mount. I believe the one that Red Feather sells should fit both.

Larry's (red feather) mount fits the 215, I have a late model 215 (not an S) and it fits fine.

This might help?
