Well...the Daniel Defense one can be bought here: https://danieldefense.com/mk18-risii-fde.html although it's a) expensive and b) ITAR restricted so they won't ship it to you. Plus it probably won't actually fit.
The Nuprol one on the other hand is out of stock pretty much everywhere.
Thanks mate its looking pretty hopeless then do you have any other suggestions for decent rail to go my we gbb m4 that would be compatible I dont like the 7inch ris rail on there

Powair6 has the Madbull licenced one in stock but shipping could be a pain because they're in France https://www.powair6.com/en/ris/1338-madbull-mk18-95-inch-daniel-defense-sopmod-ii-ris-ii-desert-tan.html
