What do I need to put a Breach on my helmet?

Parts list and considerations for Helmet Mounted Thermal (HMT) using a FLIR Breach

There are two basic methods to mount a thermal monocular to a military style helmet: mounting HMT in conjunction with a NVD (night vision device), or mounting the thermal monocular by itself without consideration for use with a NVD.

Helmet mounting thermal in conjunction with a night vision device

Below are the components needed to bridge a FLIR Breach and a PVS-14 to enable the use of both simultaneously. Keep in mind you’ll most likely want to mount HMT over your non-dominant eye, leaving your PVS-14 over your dominant (aiming) eye so you can shoot passively with a NVD-compatible optic. If you aim solely using a weapon mounted infrared laser (PEQ, DBAL, etc.) or thermal weapon sight (TWS), then you can mount your thermal monocular over either eye based on your personal preference.

1. Helmet mount interface

• While most entry level users start out with the widely available and inexpensive Rhino or Rhino II bayonet style mounts, we prefer and recommend the Wilcox G24 ($495) dovetail mount. This mount is widely considered to be the gold standard in use today. It eliminates much of the slop common in the Rhino and Rhino II by using a more advanced dovetail design.

1. Bridge

• There are a number of solutions out there for bridge setups, but in our experience the two most common bridges in common use are made by KAC/KVC (Knight’s Armament/Knight’s Vision Company) and Mod Armory.

• Knights Armament Company Universal Bridge P/N 111793 $699

• In addition to the KAC bridge, you’ll also need the following accessories:

• K-Clip Shoe Set (P/N 111791) $149

• This will provide a dovetail attachment for a FLIR Breach which utilizes a MUM interface

• Obverse Shoe Set (P/N 111782) $249

• This will provide a dovetail attachment for a PVS-14 night vision monocular

• Mod Armory D-14 bridge (P/N DT 1-14/1-FB) $575

• This will come with everything you need to mount a PVS-14 and a FLIR Breach in one package. The Breach will not be quickly detachable with this setup. If you wish to have QD capability to swap back and forth between HMT and dual PVS-14s, you’ll need to purchase the following components instead:

• Mod Armory D-14 bridge (P/N D-14) $575

• This model will come set up to run dual PVS-14s, each having a quick detach dovetail socket

• MOD Armory D14 Dovetail Adapter (P/N D14 Dovetail Adapter) $89

• This will provide an attachment which is installed on your FLIR Breach, and integrates with the quick detach dovetail sockets on the D-14 bridge.

Helmet mounting thermal as a stand-alone solution (no night vision)

If you are solely using HMT for detection, and are not using an infrared aiming laser or NVD-compatible optic, then the mounting solution is different, and typically less expensive.

1. Helmet mount interface

• While most entry level users start out with the widely available and inexpensive Rhino or Rhino II bayonet style mounts, we prefer and recommend the Wilcox G24 ($495) dovetail mount. This mount is widely considered to be the gold standard in use today. It eliminates much of the slop common in the Rhino and Rhino II by using a more advanced dovetail design.

1. J-Arm interface

• Mod Armory makes what we consider to be the most cost effective, quality j-arms if you do not intend to run HMT in conjunction with a NVD.

• Dovetail interface

• MOD Armory J Arm Adapter for Flir Breach PTQ136 (P/N Flir Breach Arm) $174.99

• This will allow you to mount a FLIR Breach to your G24 dovetail mount. It will allow you to mount your Breach over left or right eye, depending on preference.

• Bayonet interface

• MOD Armory J Arm Adapter for Flir Breach PTQ136 (P/N Breach Bayonet) $174.99

• If you already have a Rhino/Rhino II helmet mount, and do not want to upgrade to a Wilcox G24, Mod Armory makes a bayonet compatible j-arm that will allow you to mount your FLIR Breach to your existing mount.
