Not to hijack the thread or anything... I just want to clarify NY state laws on stocks... Can you have a collapsible stock pinned to make it legal or does the whole system have to be non-adjustable to begin with?
THe reason I ask is because I figured, rather than having it pinned (again, if allowed at all), you could take out the horizontal pin that allows the lever on the CTR to engage the spring for adjusting. I tried to figure it out as best I could and it appears to be more difficult to put it back in than to push out a pin to prevent adjustment. Whether or not it's legal for states that require adjustable stock pinning is an entirely different thing.
Just a thought that popped into my mind.
