If you select the 15" on the drop-down menu, and then try to add to cart, it reloads the page with a message that it's out of stock. Thus, the website can still be trusted.
Obliged that you're helping keep an eye out, regardless.
We have a couple things coming up soon, but I may be snagging another type to hold me over till the NSR is back in stock. I'm pretty set on that as the eventual handguard for this build (Lothar-Walther 20" wylde-chambered barrel with LW-matched bolt, geissele, blippity blah etc.) but since no knowing when they'll be back, Imma need something on it in the meantime to sight in and get some prairie dog mist in the works.
