From airsoftpark.com, though I had to get the silencer re threaded as it didn't fit my gun

not sure how to make the image bigger…suggestions?

My WE HK416 current mods: RA Tech trigger group RA Tech steel bolt and nozzle G&P 552 Red Dot G7P front grip VFC PeqBox Vltor charging handle Magpul sling attachments (front and rear) Magpul CTR stock (RS) …still to come: Firefly hopup & Angry Gun TB

There are afew guides On YouTube It's pretty easy

Use the m4 open bolt kit. I did in my 416 and it works fine
