## Description

desertcart.com: HGAC JDAPT J-Arm Adapter for FLIR (Formerly Armasight) Optical Devices : Sports & Outdoors

Review: Works with MUM14 (should work with ANY NVG device with MiniRail)!! - With a file, some want to, and patience, this will work on a MUM14 mini rail. I have a MUM14 and the adapters are expensive and have a lot of inherent slop, so when I saw this plate I realized the opportunity I had. After buying it and messing with it, I realized that it was indeed exactly what I had been looking for. I had to open the dovetail in the adapter by filing off some material (off of the adapter plate, NOT off of the MiniRail on the expensive NVG device!), but after that I could use standard NVG JArms, Norotos DDA, or a Wilcox JArm to attach my MUM14 to the mount. It’s well made, and inexpensive (an utter rarity in the world of Night Vision). If you’ve been looking for a way to use better mounts with your MUM14 (or NVG with minirail), then this adapter is perfect for you.
Review: People are messing around with all kinds of gadgets and DIY crap, when all they have to do is pick ... - Ordered one of these for my new Armasight spark that is attached onto a mil-spec J-arm (used but in new condition). This is mounted on a ballistic-rated fast helmet. People are messing around with all kinds of gadgets and DIY crap, when all they have to do is pick up one of these and they will be 100% in business. Well made, looks great, 20 second install and you are good-to-go. Fits snuggly and tightly (the way you want it to), to standard J-Arm and helmet mount + and it aligns the spark PERFECTLY to your eye. This is a highly recommended Item to all Spark Core Owners, at a very reasonable price. I also received this SUPER-FAST (like in 1 day). 5 STARS +++AAA++ !!!

### ⭐⭐⭐⭐ A Good Piece of Kit
*by M***O on May 9, 2019*

I can only give 4 Stars because this is not THE perfect adapter plate. I was using it to mount an ATN NVM14-WPT and it would not fit on the mini-rail. I had to use a triangular needle file to remove about .010" from each side of the dovetail. A very minor amount, and this only took about 6mins of filing to achieve the perfect fit. I know this plate was not intended for the NVM14-WPT mounting, but it does work ans is very cost effective. I would not hesitate to recommend this to anyone trying to mount a non-PVS-14 device to a standard J-arm.
