I got the helmet in and it is nearly a perfect match, and the strapping to. I have the light attachment already. I didnt realize the strapping that came with the helmet was correct. I ended up spending on a seperate strapping so I have 2 now.
Amazon - Lancer Tactical Medium - Large Industrial ABS Plastic Constructed Maritime Helmet Adjustable Crown 20mm Side Rail Adapter
Amazon - Princeton Tec Switch MPLS LED Task Light
Bad news is the rails are not correct, so I had to order those.
Amazon - "Tbest Rail Mount Helmet Adapter Tactical Military Combat Helmet Side Rails with Lanyard Mounting Screw" are the correct ones.
The ear covers I got are not correct either. Still searching for the exact match but not finding ones yet.
EDIT - found the right ones and they cost ALOT. real tactical stuff.
Gentex - OPS-CORE SIDE ARMOR - FAST
EDIT 2 - the front night vision attachment has the Gentex logo, and they are not too bad on cost. So I dont have to buy a 1000$ helmet now!
