I would be afraid the the length of pull would be too long. On my SPR I low mounted my scope and run a fixed tube with a CTR stock. I get a real tight cheek weld, right on par with an AR, and can still adjust LOP depending on clothes/vests. With the low scope mount, I can't run BUIS's but I don't on any of my other dedicated scope guns.
I've been running mine through sniper drills and it is shooting on par with my .308 and is quickly becoming my favorite precision gun.
If I can help you, let me know. These things make great SPR's.
