What is a velocity lock for?

[Skyssx]

Yes, ha-ha, for locking down the velocity adjuster. I ask because the classic adjuster doesn't seem to need any 'locking down'. It's a small, smooth screw, with very little surface to get purchase on. Were they "just because" kinds of things, or would they still be required today if someone used a classic mag in a tournament? Why don't the RT and descendant valves use them? I know the RT velocity adjuster is larger in diameter.

the purpose of it was to be able to adjust your velocity without an 1/8 allen. easier. but for tourny's they wanted to make sure you couldnt do it on the field so they put a lock on it

So the velocity lock ring clamps to the velocity adjuster? The LAPCO adjuster would make more sense if that was the case.

true but when mags were popular everyone and their momma made a thumb adjust and everyone had to be different

Good old turney lock. From a time when tournaments were held in the woods. And people had time to cheat with FPS.
