I've got a Vortex Strike Eagle 5-25x50 on it, and the best part is that it feeds from 10/22 mags. Pics later when I get to my phone.

S&B Club sub-MOA at 100 yards? Consistently?
Didn't do so well in this test. Note: These were 5 consecutive 5-shot strings, fired through a $10,000 Bleiker single shot .22LR with hand-lapped Lilja barrel (tuner equipped), with two stage trigger to try to eliminate as many non-ammo confounding factors as possible. I don't know the trigger weight setting for those tests. That action/barrel combo is considered to be perhaps the most accurate .22LR "off the shelf" available at any price and is the top choice of most international competition shooters. The scope was a Leupold 8.5-25x50 LR target scope with sunshade, set at 25x.
I can see MOA at 50 yards. Christiansen guarantees that, but 100 yard MOA is daunting with the best equipment and ammo. Maybe S&B Club could luck into it occasionally, but consistently?
I agree that some.22LR barrels have clear ammo preferences, but S&B Club almost always groups close to 2MOA at 100 yards from multiple comparison tests. It seems to group well at 50 yards, within 1MOA in good rifles, but as distance increases, the groups start falling apart.
I guess you just got an exceptionally good lot.
The tests were performed under controlled benchrest conditions at an indoor ammo test facility.
