Other than price, any significant difference between the two? Looking to build a rifle inside a Foundation Stock (MG2).
Thanks!
Both are functionally good to go.
Technically the KMW Mk1 , SENTINEL and Surgeon DBMs are more robust parts because their inlet is larger than the M5.
This may be of little significance to most since most but not all of the thinner walls of an M5 style inlet are protected within the stock.
Why a cost difference?
The KMW design chose to include a good bit more chamfering and sculpting. More chamfers = less sharp edges against your hands in and outside the trigger guard. The increased wall thickness of the KMW hardware also allows a good bit more "flare" to the entrance of the magazine well.
In addition to pillars of the correct length, HoloKrome stock bolts cut the exact length needed are included.
When a DBM is installed correctly, the stock bolt lengths will always be a fixed dimension. Providing the stock bolts pre-cut does away with another sometimes tedious job usually required after purchase.
Choosing to go with this design and these features means more machine time and higher cost. That decision was made on purpose to offer the best evolution of DBM that I could.
Both will give you excellent service.
Excellent choice on the Foundation btw....
Be safe and stay healthy.
