Nothing like that has been suggested or confirmed from Stag directly. One post indicated Stag was going to start offering M4 feedramps in new production rifles from a member not StagArms themselves. Nothing at all from Stag indicating they were going to do any M4 ramps for 'existing' customers either. I think Stag is only just beginning to come around.
I am optimistic about Stag incorporating M4 feed ramps and that move would put them as one of the better production 6.8 products in the market. I would suggest waiting to see what they do if anything first as we have had good news turn the other way before.
Stag did express an interest in correcting the mismarked barrels that were marked 1:11 twist, but actually had 1:10. This seems to be confined to the Model 5, not the 7 as member feedback has the M7 barrels are actually 1:11 as specified.
