Description
This is the full MARK 2.0 AMP kit from Unity Tactical, built specifically to marry the Ops-Core AMP communication headset to your lid. Because it comes with the Ops-Core hardware, you get the OEM AMP cradle clamp assemblies in the box, which means you can attach it to your headset and be running fast without hunting for extra parts. It mounts at the traditional 12 o'clock position and works even on helmets that don't have a rear rail, like the Crye Precision AirFrame, which is where a lot of the older factory mounts leave you stuck.
Why the MARK 2.0 AMP Runs Lower Than the Rest
Unity built this to be the most compact headset helmet mount out there, and it shows. Instead of the old pop-in, pop-out cups, the MARK 2.0 lets you pull the ear cups away and rotate them backward for stowage. The wire forms are aggressive on purpose, so when the cups are engaged they pull tight against your ears for a stronger, more consistent seal and a better noise reduction rating. It's molded from impact-resistant polymer and holds up to genuinely rough use.
Rails the MARK 2.0 AMP Kit Fits
This kit ships with all the hardware for Ops-Core ARC rails and similar copies, plus Team Wendy EXFIL Gen 2 and Gen 3 rails. That covers the Ops-Core FAST series, Crye AirFrame, Galvion Caiman and Viper rails, and most ARC-style setups. The 2.0 also runs wider ARC backer plates than the previous version, so it plays nicer with non-standard rails that used to be a headache. If you're running an MTEK or Hard Head Veterans helmet, Unity offers an M-LOK adapter kit separately.
One thing worth knowing up front: this version is made to work only with the Ops-Core AMP headset. The AMP wire forms are a different length and crimp direction than the legacy MARK 2.0 forms, so they aren't cross-compatible. If you're running Peltor or Sordin ear pro instead, Unity makes a separate MARK 2.0 kit for those.

Frequently Asked Questions
Does the MARK 2.0 AMP kit come with the cradle clamps I need?
Yes. This is the full kit with Ops-Core hardware, so the OEM AMP cradle clamp assemblies are included in the box. That means you can attach it straight to your AMP headset and mount up without sourcing extra parts, unlike the MARK-only version that leaves the clamps to you.
Will the MARK 2.0 AMP work with Peltor or Sordin headsets?
No, this version is built to run exclusively with the Ops-Core AMP headset. The AMP wire forms use a different length and crimp direction than the legacy forms, so they aren't cross-compatible with other ear pro. Unity makes a separate MARK 2.0 kit designed for Peltor and Sordin/MSA style headsets.
What helmet rails does this kit fit?
It ships with hardware for Ops-Core ARC rails and similar copies, plus Team Wendy EXFIL Gen 2 and Gen 3 rails. That covers Ops-Core FAST helmets, Crye AirFrame, and Galvion Caiman and Viper rails. For MTEK or Hard Head Veterans helmets, you'll want the M-LOK adapter kit, which is sold separately.
Can I use the MARK 2.0 AMP on a helmet with no rear rail?
That's actually one of its strengths. It mounts at the 12 o'clock position, so it lets you run an AMP headset on helmets that lack a rear rail, like the Crye Precision AirFrame. That's a spot where the standard OEM AMP mount, which attaches from the rear of the rail, can leave you without a good option.
