How to mount an OPSIN on a helmet

 

Here is some information about putting an OPSIN on a helmet.

 

6 things fit together:

  Helmet

  Mounting Shroud – most helmets come with this already

  Mount

  Swing Arm / Adaptor for Dovetail or Bayonet

  OPSIN

  Battery & cable & pouch

 

There are 2 basic types of helmets:  Bump and Ballistic

 

Bump helmets are lighter, cheaper, and protect your head from bumps, like a bicycle helmet does.

Ballistic helmets are much heavier, expensive, and are made to stop/deflect bullets.

For most civilian purposes, the bump helmet will be cheaper, and less effort to wear for long periods of time.

Do I buy this separately?   Yes

 

Most helmets already come with them.  See highlighted in picture below.

Most are 3-hole type, which is what you want for the OPSIN.

Do I buy this separately?   Not likely, most helmets come with one.

 

 

 

There are 2 common types:  Bayonet and Dovetail

 

There are different makers for Mounts, but we recommend the Cadex Mount.  This works seamlessly with our Swing arm.  We offer these on our website, but you can find them elsewhere.

Another maker of a dovetail Mount is Wilcox.  We recommend the Wilcox G24 Mount.  Search Google, or visit the

 Wilcox website G24 page for a list of dealers.  NOTE:  Wilcox makes both bayonet and dovetail mounts so be sure you read the site closely.

 

Do I need to buy a Mount separately?  Yes

 

       

 

 

 

The connecting piece from the monocular to the hinged Mount.   There are 2 common Swing Arm types:   Bayonet and Dovetail.  

Do I need to buy this separately?    A Dovetail adaptor comes included with the OPSIN.  If you have a Dovetail mount, No, you do not need buy this separately.  If you have a Bayonet mount, Yes, you will need to buy an adaptor to fit the Bayonet mount.  We sell these on our website, or you can google them to find them elsewhere.

 

This has a mini-rail attachment built into it that attaches to the Swing Arm included in the OPSIN box.

 

Cable connection from the OSPIN to the battery.   The battery sits in a battery pouch that velcros to the back of the helmet.

Do I need to buy these separately?  No, the battery, cable and pouch come included with the OPSIN.

 

 

Here is a good 3rd party video to see how they all connect up together.
