Canadian eh!
Regular
Like I said before, the reason, and the only reason, people hold on to the magwell is that regular C7/M16 barrel is not free floated. The POI can change up to 6-8MOA if you force it with aggressive hold like what you said. That's why in an all military shoot like the CFSAC, everyone holds on the the magwell - and that practice has its root in the military where plain jane non-free floated C7/M16s had been used for aeons.
Know your weapon construction, figure out what you need to achieve, and pick the appropriate technique.
Starting service rifle next year as well. I am using a normal grip on the handguard currently, but my current setup is not free floated. Based on this info it looks like I am in the market for one
