I didn't see where anyone stated the W3 is a "lite" version. What I stated is that it is not a fair comparison to compare the Magpul with the lightest or the heaviest stocks in the same class. Just as you said it is 25% lighter, I could say the magpul is also 25% lighter than a JAE chassis. Its very easy to point out major differences when the single example used is on the extreme end of a single feature.
You have to compare the average weight across the chassis systems in which it directly competes. The poster above you was attempting to compare the Magpul to systems intentionally designed to be lighter weight systems. He said it was a boat anchor compared to an MPA lite.......no shit, its not a
"Magpul Lite." This would be the equivalent to saying "well shit, my MTU barrel sucks because it's not as light as my sporter barrel."
You then put up the W3 as an single example (the W3 is in the same class as the Magpul) and failed to mention that it is equally as heavy as many other chassis and also lighter than many other chassis systems.
I'm merely pointing out that when compared to the overall weight of chassis in the same class, the Magpul is of average weight.
And as far as "put to rest," I have no clue where you are coming up with that. As the Magpul allows the user to configure their trigger finger "length of pull" by adjusting the distance of the grip from the trigger guard. This alone put it in an entirely new class of adjustability. So, It's not just the swapping of left/right (which is also a huge difference).
Just adding those two additions to the list of adjustments typically found on some other stocks currently puts the Magpul into a class of its own.
