What have you made?

The real legend that is @Anonymoose came through me again yesterday; (what should be) the last custom part required for the Geissele AEG.

The selector is a combo of a real G$ lever, the internal cam disc from a basic/standard ICS AR selector, and then a very complex little adapter piece inbetween machined from ali. Tolerances are spot on, no wobble in it, zero slop, takes a firm press to change between modes.

Well I bought a new helmet. It's an FMA clone of the Team Wendy Exfil and it has, what looks like, one of the better liners/suspension systems i've seen rather than just using blocks of foam. The problem is that my eye protection is attached to my current helmet via the arc rails and the mount that came with my ESS goggles - the Exfil does not use Arc rails, rather it uses T-slot rails and some picatinny.

I assumed that, surely, someone sells a simple mounting solution for the T-slot rails... right? Well yes, Team Wendy do the specific mount I need - for $80 and they wont sell directly to the UK. Any UK/EU retailers I found with them in stock are 80/90 euros... for two weld nuts, two thumbscrews and the ESS mount. I decided to tackle it myself because i'm cheap and how hard could it be?

I measured the width and depth of the T-shaped channel to see what I needed. There were no actual weld nuts that met the sizes I needed so I eventually settled on some M4 12mm x 10mm x 3mm T-nuts that I found on ebay. They were the closest thing I could get to the correct size but they were a little too small and a little too thin so I 3D printed a piece for them to sit in. It doesn't look like a lot but it removes 99% of the movement it had inside the rail.





After this I went on Amazon and found a variety box of thumbscrews that had a few different lengths of M4 thumbscrews and ended up using a M4x12mm one. My next issue is designing the part to take the place of the ESS mount that the goggles actually secure onto. I couldn't just drill a hole right through the original mount as it would damage the nub that allows the block to secure into the Arc rail mounts and I don't want to damage these just yet. This step probably took me the longest to do as I had to make a couple of different version to get it right.







I could probably clean the design up by finding thumbscrews that have a slot on top so I can recess them further into the mount to clean up the look of it but, for now, it works. All in I spent about £17 - £13 for the box of thumbscrews and £4 for the T-nuts and a negligible cost for the 3D print. I printed the mounts in PLA+ but will reprint them in something more weather resistant like PETG should I decide to stick with the 3D printed version.

I did all this to then find that WileyX also make a similar mount for their Spear and Nerve goggles all for £43 (including £15 postage by the way) but I have no idea if the sizes are compatible with the ESS goggles - it's something I may look into in the future.
