Why? The 5.7 is like a mini .223, only costing 2x-3x more for ammunition
with less potency. I can see maybe for a pistol, but too little bang-for-buck
for an ar15 rifle. Just my $.02

It could be done, and M1 carbine mags could be used.

Why?
Why not?

People use .22 lr, 9mm, etc. uppers.

it can be done, but its not economically right--ammo is too expensive and scarce; change the ammo availability, then some might bite

there are .22 lr b/c its cheap to shoot; there is 9mm cause its roughly the same price to shoot as .223 and its quieter and different, but not exotic

The idea is build a ultra short carbine (maybe 6 or7" barrel) and efective, (ala P90), the 5.7 works better than 5.56 in short barrels, with less recoil and flash.....

true, but ammo costs sure doesnt help

krink's idea is nice, but it would be best to have a SBR

I want a bolt gun in 5.7, that could make a nice rifle to fill the void from .22 and .223 for varmints
