The A1M Vader is one of the best gunstocks out there on the market. You're able to quickly reload without the controller hitting the gunstock and have a lot of adjustability that is easy to adjust on the fly.
I've tried gunstocks that have a V-shape where they're just two pvc pipes at an angle and those ones are not as great in my opinion.
Being able to detach the front segment from the stock magnetically is a game changer for switching to pistols on the fly or grabbing things in game.
I also have an A1Mbot front-end module and being able to switch between the A1M vader and A1Mbot pieces is easy and useful. The stable frontend of the A1M Vader is great for fps games where I don't need to pick up things off the ground and the A1Mbot is great for everything else.
There were a few games that I've played that do not have in-game gun positioning adjustments but I reached out to Simon and he was able to show me SteamVR's native offsetting for gun positioning. This was crucial in ensuring that the gun lined up with the stock perfectly and to avoid the magazine hitting the frame of the gun when not lined up.
The only thing I could recommend for the product is to have a module starting from the handguard position of the frame that allows for vertical adjustability from that point. That would allow the entire front grip portion to move physically and avoid having to utilize in-game adjustments entirely.
Amazing product and amazing customer service, I am excited to see what comes next from KobraVR.
