I am not so sure about it, but could it be flex hose cut to size? http://www.bricklink.com/catalogItem.asp?P=78c02 You should probably ask the creator directly :)

You can see the cut hose technique in other MOCs in the series, especially [here](https://www.flickr.com/photos/legocy/16384530492/in/photostream/) and [here](https://www.flickr.com/photos/legocy/16197822918/in/photostream/)

<p>The bit held in the mech hand is a <a href="http://www.bricklink.com/catalogList.asp?q=ray%20gun" rel="noreferrer">Ray gun</a>.</p>

<p>The bit on the forearms is almost certainly a short bit of <a href="http://www.bricklink.com/catalogItem.asp?P=78c02" rel="noreferrer">Hose, Ribbed 7mm D. 2L</a> like zovits said.</p>

It is a [Tile 1 x 1 Round, with groove](https://www.bricklink.com/catalogItem.asp?P=98138)

Edit after clarification in the question:

The arms have something that looks like a bit of [Hose, Ribbed](http://www.bricklink.com/catalogItem.asp?P=78c02) cut to the required size.

The gun is, as username_2 pointed out, based on a standalone [ray gun piece](http://www.bricklink.com/catalogItemPic.asp?P=13608) that has the ribbed section molded in originally.

The bit held in the mech hand is a [Ray gun](http://www.bricklink.com/catalogList.asp?q=ray%20gun).

The bit on the forearms is almost certainly a short bit of [Hose, Ribbed 7mm D. 2L](http://www.bricklink.com/catalogItem.asp?P=78c02) like username_1 said.
