Why did H&AIDS discontinue them? They were one of their few modern civilian market offerings that actually seemed worthwhile as more than just a novelty or a base for an expensive aftermarket conversion job.
They're what the Ruger Mini and all the shitty overpriced M14 repros wish they were. They were more reliable, way more accurate and had way better build quality.
Bet they'd make bank off these in ban states if they were to bring them back in both the original and a slightly updated configuration with polymer furniture and Picatinny railz OOB.
