In my opinion there is nothing innovative or radically new about this.
If you look at what the aftermarket has done with the existing parts one can easily create a lighter 308 totally compatible with exiting lowers.
Fluted and lightened carriers, fluted and lightened upper recievers, flutes/cuts for the lowers, medium and light barrel profiles with proper gas
setup and patterns.
I have one of them to hunt in 7.6lbs dry and it can be made even lighter. The lowers can be lightened w/o compromising their structural integrity and preserving
all contact dimensions. If you look at the AR15performance upper the whole idea lightening the entire upper makes a lot more sense and if one wants to reuse the
smaller brother tubes /handguards that is not a huge thing for me anyway.
They all feel and shoot as the AR15 (except recoil) as they observe pretty similar external dimensions. Also assures compatibility with existing platforms including the ones already
in service.
I feel this is where DPMS or anyone should be concentrating right now as it is demonstrated to work and is becoming the standard and this way people would have more
lither parts assortment, more affordable and w/o having to send anything to a mill.
DPMS/Remigton and Bushmaster are all from the same group and they have been doing the spaghetti approach for a while, you know throw it to the wall and see
if sticks. We cannot blame it others are doing the same thing. But if they only listened to their enthusiasts and worked with them and the experts and shooting
community they would be having more successes.
