The 80% lower market has just gotten a little more diverse. Ghostguns.com (not to be confused with Defense Distributed’s Ghost Gunner) just announced they’re developing an 80% insert for the SIG P320. Why is this a big deal?

Simple. The P320 is fully modular, a big reason the US Army fell in love with it. The only part of a SIG P320 that’s legally considered a “firearm” is the serialized internal frame. You can have any other part from barrel to slide to trigger to grip delivered directly to your home via the big brown truck.

Now, thanks to ghostguns.com, you can avoid all the paperwork and the transfer fee that’s involved with that with internal metal frame. All you have to do is a little grinding and drilling on your own using the tools and jigs ghostguns.com just to happens to conveniently sell, too (same as the 80% lowers sold for AR’s).

We don’t have any information on pricing yet but we’ve reached out to ghostguns.com and are efforting that now. Stay tuned.
