Using PMII 3-20x50 on TRG 22 and SP10 with QDP-4602 – viable plan?

[Filip]

Currently running a Schmidt & Bender PMII 3-20x50 on my Sako TRG 22 (6.5 Creedmoor) using a Spuhr ST-4701 (35 mm height, 7 MIL cant, direct to dovetail).

I recently bought a Seekins SP10 in .308 (18” barrel) and I’d like to run the same scope on both rifles.

I’m considering switching to a Spuhr QDP-4602 (34 mm tubering, 38 mm height, 6 MIL cant) and installing a low-profile 0 MOA Picatinny rail on the TRG.

That would let me swap the PMII between the two rifles using QD, and use marked zero offsets.

My questions:

1. Do you think this is a solid plan or would you recommend running two separate optics instead?

2. Is there any practical downside to the increased scope height on the TRG (from 35 mm to 43 mm centerline)?

3. Any experience with RTZ performance using QDP mounts across bolt and gas guns?

Appreciate any thoughts or feedback!

Really, you can make anything work with enough effort - or money. I guess if you're alright verifying your zero every time that you swap it, it would work, but why not just hit the easy button and get another scope?

Yeah, totally get what you’re saying — getting a second scope would definitely be the easiest way.

For me, it mostly comes down to budget. A second PMII (or anything close) is a big investment, and right now I’d rather put that money toward ammo, training, or maybe another optic later on.

If the QDP setup holds zero well enough, it seems like a pretty reasonable compromise.
