Nerf/Hasbro has said that the reason they don't make more accessories for blasters is because of plastic costs. This is why they don't release them outside being packaged with blasters. There is demand from fans for the separate release of things like shoulder stocks or foregrips, or the creation of useful accessories like tactical rail ammunition or clip holders, but Hasbro's not interested in following up with them because of money reasons.

That's why 3D printing and fan companies like SlyDev are great for the community.
