I slapped a spare Weaver 2.5-8x on top after taking off the rear sight. Realistically, a 2-6x would be a better fit, but this one had rings on it already so I didn't need to find a pair. After sighting in at ~15 yards I moved the target back to the 50 yard mark. I was only able to get four groups in before running out of daylight. The groups were decent, 1.5-2", but I had a problem with horizontal stringing. It took me a while, but I figured out I wasn't pulling the trigger straight back. It seems like the Buster has longer-than-expected lock time, exacerbating the problem. That being said, it's not the gun, it's the shooter. Overall, the trigger is decent. I don't really feel the need to adjust it. There is minimal creep and it's not overly heavy. An overtravel stop might improve the consistency, but I don't think it's necessary. One more annoying thing: I wasn't able to get the thread protector off in time to test my Buckmark moderator. I'm going to need something like a strap wrench to get a grip on it. As-is, it's not .22lr loud, but if I had neighbors nearby I would be concerned.
If I get a wild hair I'll do an in-depth review after testing all my pellets, but overall I'm relatively pleased. For ~$250 it seems worth it. I still might get a Notos to compare, but I'm not particularly interested in a pistol/carbine hybrid.
