Basically you got a NULA as the prototype had the lighter stock. For production runs I think they changed something in the lay up. Still light but it sounds slightly different than the NULA stock.

I do plenty of tail chasing in load work up. Can't stop too fast or the inversion could happen.

"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
