Advanced Feed Tube Spacer


(3 customer reviews)

Extra support for the Hop-Up

Out of stock



Let us introduce you a small but important part for the Forged and New Billet series with the Advanced Feed Tube.

The Hop-Up in some cases needs extra support and thats what this spacer does. It prevents side to side wobble and aligns the feed tube hole with the Hop-Up chamber hole for improved feeding.

Due to the tolerances some MTWs need this some not but it is a nice addition to make sure everything is aligned.


Why is it good?

-Perfect alignment with the feed tube

-Prevents wobble in the system

-CNC aluminum with hard anodize

-Has set screws to minimize tolerances and wobble with specific chambers

-Improves feeding and accuracy



Why is this better than adding wings to the Hop-Up?

-You can use it with our Alpha, Stock, Forged and Phoenix Hop-Up so it is not Alpha specific, we wanted to make an universal solution. (Phoenix is a bit different than the other three so there is a possibility it won’t work as intended, in our case it works so Phoenix users, please buy with keeping this in mind!)

-The wings align the Hop-Up to the outer barrel not the feed tube, so if the outer is twisted, the chamber won’t be aligned with the feed tube.


What’s included?

-The CNC Spacer

-2 set screws



Simply put it onto the chamber when it is already in the MTW, you can’t add and screw it to the chamber, screws are just for minimizing tolerances and play! After adding it there simply install the feed tube.

  1. Marcos demilios

    Nicely built but leaves about a mm or two gap between this spacer and the upper receiver. Personally I experience no change in accuracy, grouping or range with this part

    • Silentadminzs

      The spacer is not supposed to touch the receiver as it centers the chamber to the Advanced Feed Tube.
      Range couldn’t be improved with this part as this is for improving feeding reliability.
      Thanks for the Feedback!

  2. Paul Cole (verified owner)

    Holds the hop unit in perfectly and removes the possibility of any sideways movement

  3. Chris Llewellyn (verified owner)

    Before installing this, my EPM1 magazines would not feed consistently. After installing this, they work flawlessly.

    *Disclaimer that I did pair this with the Silent Industries red MTW nozzle, so not sure which one fixed my issue or if it was a combination of the two.
