With the likelihood of new 6.8mm SPC barrels emerging in the months ahead, does it make much difference of getting the M4 ramp style? Is it actually stronger? Or is it just more reliable for slightly heavier bullets? The cost appears much more than a standard rifle extension, and it also requires a special receiver, so understanding the difference would be appreciated. Any thoughts?

The only pro I had with no ramps is the S.state ammo with the flat nose would not feed very well. I have cut ramps in both upper and barrel ext. and now they feed fine.;)
