Only have had Leupold's on my Kimber's.
On 84M's I've had:
6x36
2-7x33
2.5-8x36
On 84L's I've had:
6x36
2.5-8x36
3-9x40
3.5-10x40
For both my favorite is the 6x36 or 2.5-8x36.
For 84M only, the 2-7x33 is very nice too.
For 84L only, the 3-9x40 or 3.5-10X40 are fine. But I'm still prejudiced (some would say irrationally) to big scopes on light rifles.
