Initially the HK416's were fitted with US made metal EPC's. After some time newer HK416's were fitted with a plastic ones made by HK or their sub for that. Primarily because it reduces supply issues and once the mold is made plastic ones are next to no cost to make. Over time HK has made many/most of the parts for these guns as there were supply issues and QA issues with other suppliers. You can best control such things by making all in house or with nearby subs.Ive seen some threads on here hit on the topic but never any oppions on which one members prefer.
Polymer or Metal...what would you chose and why ?
Would you replace the metal 416 ejection port cover with the mr556 polymer one ?
No issues with the covers, when it comes to durability.AGR notes that the 416Ns come with polymer. How have they held up in the cold and in the sandbox so far?
Only the early models came with metals ones. I don't know the date code cut-off, but yep, the all have polymer now. The oldest with plastic that I have seen so far is AH.The HK416 has a polymer ejection port cover.....at least ours do.
