I believe the Grendel uses a bolt for the 7.62X39 round.
The comparison on the pepper poppers is not quite fair as the M-4 hits were lower that the other two calibers. Low hits equal less leverage to knock down the popper.
The comparison to the saw was earlier in that episode, something about soldiers (AHEM) and Marines! getting the round belt caught and dettached. So theyre equiping them with the Grendel which has the same stopping power as the saw. Also less over heating so less chance of rounds going off accidently. I just wasnt sure if its the same one you guys have on this forum. I think that Seal was commissioned by colt to sell some AR-15's, so he messed up the shots.
