The M42A2 DMR is a bullpup long barrel weapon in the same family as the M41A Pulse Rifle from the movie Aliens.
When I redesigned the M41A I envisioned it as a part of a modular family of weapons sharing common components. The core receiver component can be combined with various barrels, lower receivers and attachments to perform different roles. The M42A2 shown here has a longer barrel with integrated under barrel smart scope and would be intended as a longer ranged alternative to the M41A. There's no integrated display for the scope as the image would be displayed wirelessly on a helmet mounted display.
The inspiration for this were the L85 rifles used as set dressing on the Sulaco in Aliens. It was a fun challenge to try and adapt the design language of the original Pulse Rifle to a bullpup design. The original has a certain funky 80's quality to it that's hard to capture, but I'm really happy with the end result here.
