Duality Arms HK G36 .22LR Mamba Trigger

The Duality Arms HK G36 .22LR Mamba Trigger brings the Mamba layout Duality built for the KRISS Vector onto a rimfire host. Duality sells it as an assisted-reset kit rather than a full fire-control replacement, and the gun stays semi-automatic at one round per trigger pull.

The operating layout is two positions, SAFE and ASSISTED RESET. Duality is explicit that the Mamba configuration removes the traditional semi-auto selector position, so this is not a kit you install and then run in a conventional semi position when you feel like it. The kit ships a dedicated reset module 3D-printed from Hyper PLA-CF along with a reduced-weight trigger spring chosen to match the system's reset behavior, and Duality links an installation video from the product page.

Fitment is narrow and worth stating plainly: Duality designed this for the G36 .22LR platform and specifies nothing else. It is not a 5.56 G36 part and it is not an HK SL8 part; those centerfire hosts run a different fire control and none of this kit crosses over. The rimfire framing is also the appeal, since a .22LR host makes assisted-reset shooting cheap per round. Assisted-reset and forced-reset device legality is state-specific and still moving, so confirm current federal, state, and local law before ordering.
