Polymer80
American manufacturer of firearm parts kits

Polymer80, Inc. was an American manufacturer of firearms parts kits that included unfinished receivers (also known as "80 percent" receivers) used for making privately made firearms. The company was founded in 2013 by Loran Kelley Jr. and David Borges and was headquartered in Dayton, Nevada. Polymer80 received press attention for the frequent use of its products in crimes involving so-called "ghost guns", which in specific cases resulted in lawsuits being brought against the company. In July 2024, Polymer80 ceased operations and began liquidating its assets.
Background
Since 1968, U.S. persons involved in the business of the manufacture or distribution of firearms must have a Federal Firearms License and serialize their products. However, the creation and possession of unserialized firearms for non-commercial purposes (i.e. personal use) is generally legal and unregulated under federal law. Typically, only a single, finished part of a weapon is considered to be a "firearm" according to the Gun Control Act, and this is most often the weapon's frame or receiver.

Why this record matters
The phrase “american manufacturer of firearm parts kits” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Oct 13, 2025. The linked authority identifier is Q86728341. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2013, 2024 and 1968.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
