HK 416 Bolt Head Complete - HKPARTS.NET
MR556 | Bolt - HKPARTS.NET
What exactly is the difference between a MR556 bolt head versus a 416 bolt head? From what I know the main difference between the MR and 416 in terms of BCG is the carrier itself due to the relief cut in the MR carrier to prevent the 416 BCG from being used in MR upper. The rest of the components should be equivalent in terms of quality/function from what I can see comparing both my BCGs. Is it just a "German" thing in terms of the price difference?
