RRA says they have them in stock, and I have been wanting to get a hunting caliber upper for hogs. Just not wanting one that will blow a hole out the other side. But, a big bore is interesting for me in other uses.
No, they are not the same magazines, , there is a group of us wantiing MagPul to start making the special 10 round .458 SOCOM magazines so that after the mag limit goes into effect, we will still be able to buy them........
