Full range length of pull for those of us who like a solidly shouldered weapon
None, this is a full step ahead of other stocks on the market
The characteristics of this stock complete the milsim marker, giving it true rifle/carbine size, feel, and balance. All other products I have seen or used still keep the marker as a speedball type set up with overly short stocks that are designed to be more used aesthetically it seems, then functionally. The Stock uses frictino instead of a spring to hold it in place (eliminating my finger mashing issue with the G36 stock) and balances out the barrel and foregrip nicely, the full size the item isn't heavy or awkward in any way shape or form.
It's a superbly made product, and does as it's supposed to do in providing a full stock for the X7 marker. Not for people looking to keep their markers tiny, but very much an enhancement for those who like a stock in their shoulders when putting paint down range
