Quoted:
If your using different uppers and different ammo I would use neither. If you are the edge of smoothness with 5.56 then wolf 223 will not cycle, and your different uppers and calibers will all be different also. You can keep standard and xtra power buffer springs on hand, along with a variety of buffers and find the fit for each.
Complete weapons in different calibers
NO steel cased in 556 = No Wolf
I think you missed the point. The A5 will allow you to shoot almost any ammo. It just like a A2 Rifle Stock, with no jolt
like the CAR Stock
With the adjustable tube you don't need a bunch of parts for each ammo, no changing buffers and springs, so
just trying to see if the MGI tubes are any good and if they will work with the A5. Or should I just run the A5
and shit can any ammo that won't cycle
