Grendel hybrid

[A5BLASTER]

The Six8 mags still have limited COL, but are fatter so that they could make a magazine out of polymer that would stack the 6.8 cases correctly and feed, rather than trying to fit 30rd mags in the AR15 receiver set with steel mags.

That requires a new, fatter Magwell receiver set for the Six8, but there aren't any real COL advantages with the Six8 PMAGs. They allow up to 2.295" COL before they start to seize up with case taper stacking/COL considerations for a box mag.

2.400"-2.500" COL is what the Grendel needs if you want a long-throat wildcat shooting longer bullets.

Problem with Grendel and the longer, heavier pills is drop, which is why the 6mm AR and the new developments with the .257" bore make more sense for me personally.

Yes sir I understand that.

What I'm saying is I seen a pic of the two recovers next too each other and the 68 lower is indeed longer in the interior room.

So if you was to window the mag I belive a longer coal then in a ar15 lower could be used.

Now if someone was to make metal mags for that 68 lower then it would be something worth chasing I'm sure.
