Description
ENTERS PRODUCTION 5/1
ESTIMATED DROP LATE JUNE
A fully self-contained drop-in cassette trigger unit built on our ARC-Fire technology. Designed from the ground up for HK roller-delayed platforms.
The ARHK installs directly into factory OEM polymer housings with no modifications required. Ejector comes pre-installed, no additional trips, buffers, or auxiliary parts needed in the host.
Three-position selector. Safe / Semi / Active Reset. Aligned with Navy-style housing markings (SEF to follow soon). Semi mode is fully disengaged with no active reset, giving you a standard trigger pull in the second position. Flip to the third position to engage the ARC-Fire clutch for active reset.
Platform compatibility:
MP5 · MP5K · AP53 · G3/91 · HK21 · HK31 · HK11 clones and other variants. Not recommended for use with CETME
Works with all bolt carrier types. Full-auto carriers are not required, but full compatibility is maintained if your host runs one.
