They come up on ebay every now an again, I think a few of the airsoft/skirmish sites still list them for sale, I have one as it fits my NV rifle perfectly.Pity you can’t get a web-tex sniper bag now.
Had mine for years and it’s great.
I also have a ridgeline drag bag which is very well made, a shooterking backpack carrier and an erblestock, I have a double dragbag which can get very heavy depending on rifle combo.
The one I tend to use the most a ridge line mat/bag fitted with a z-aim sling, quite low profile and I always have an insulated and dry shooting position
