PLASTIC trigger and trigger housing. NO CHOKES INCLUDED for the Interchangeable choke system for versatility across shooting applications. The stock and forend are cheap, I took the stock and forend I removed from my Panzer Arms M4 and put them on the Century Arms A4. I was actually impressed they fit. I tried to put the Strike Industries forend on, but it doesn't come close to fitting . This does give a more Italian look to the A4. The hammer is not of quality metal and the forming of it is even worse! I expect this to break/deform within 50 rounds. The carrier seems to be one of the best part of the gun, silky smooth and shiny. I do like the tungsten color. If this will last shooting more than 500 rounds, I will upgrade from 1 to 3 or 4 due to cost. I wish photos could be added.
