416 Users

Hello everyone, 

I'm new to the forum, but I am trying to gain some information from HK416 (Upper) users.

I recently acquired a AF Date code 10.4 416 upper. In most of my reading I am hearing that the system beats itself to death with use with a suppressor, especially the KAC NT4, which kind of surprises me.

To my question, can anyone here shed some light on what they did to mitigate the large amount of back pressure this setup is supposed to create. I wont be able to get out to the range for a bit, so i'm trying to be proactive in the mean time.

I have already ordered a Vltor A5 Tube, Spring-co Green Spring and a A5H3 buffer. I gained that information from here in an older post. 

Sorry to be long winded, but if has anything to add, Id love to hear it. 

Thanks

Well you might find more info over on HKPRO? I have a 10.4 upper with the 10" non adjustable GB & a 14.5" A5 upper with adjustable GB, while I don't run suppressed I still use the standard HK spring, which in my understanding can handle suppressed fire? having said that, I have read that some guns with the non adjustable GB may not run suppressed, however that could be an ammo or suppressor issue? 

Good luck , Cheers
