For the discriminating Bullpup'er: A 6.5mm Grendel-chambered Desert Tech MDR

[SHORT-N-SASSY]

Personally, with the Grendel, I'd op for using the .308 pmags if feasible.

[SIZE="3"]I think I know where you're going with that: (http://forum.snipershide.com/snipers-hid...ost2904640).

Then, there's the K&M Arms M17S, with beefy 3-lug triangular Bolt and planned 6.5mm Grendel chambering: (http://bullpupforum.com/index.php?topic=...4#msg45534).
