I was going to suggest something as small and light as possible. with as small a rear ocular bell as possible. I have a leupold fxii 2.5x20 on my suppressed marlin, and a burris timberline 2-7x26 on the 30/30. You will want to mount the scope as low as possible because the stock really has too much drop in the comb to run optics well (kind of like the m1a) Complicating things is the hammer. you will want the spur unless you can get away with mounting the scope forward of the hammer. It just so happened for me that the long eye relief of the fxii was enough to get the scope forward of the hammer.
I have a leupold 1-4x20 vx freedom on an sbr upper for my AR, and a primary arms 1-6x30 illuminated on another. The primary arms is significantly larger and heavier than the leupold. You might find the extra 8oz and 1.25" length of the strike eagle is too much for that little carbine. I don't actually like leupold scopes much, at least the low end stuff I can afford, but they sure are nice and small for my carbines.....
for what it's worth, I'm using the leupold vertical split rings and a warne base on my scoped marlins. the warne bases sit about 1/8" lower than the competition, and the vertical splits seem sleeker to me.
