Firearm Specs

Firearm Specs reads the specs of firearms and ammunition from product titles and shows them on your site. Give it "Glock 19 Gen 5 MOS 9mm 4.02in 15rd Pistol" and it shows the model (Glock 19 Gen 5 MOS), the caliber (9×19mm Parabellum), the capacity (15 rounds) and the barrel length (4.02 in). For ammunition it reads the round count and shows the cost per round: "Federal American Eagle 5.56x45mm 55gr FMJ 1000 Rounds" at $449.99 is $0.45 per round.

It is built on the open source title parser of GunsNPrices, a price comparison site for guns and ammunition that uses it to match the same product across 40+ US stores. The parser knows 293 calibers with their retailer spellings and the models of 50 brands, and it runs on your server: the module never sends titles anywhere.

Features

• Firearm specs field formatter: a list of the specs found in a text field (type, brand, model, caliber, caliber type, capacity, barrel length, rounds per box).
• Firearm spec (single value) formatter: one spec, for Views table columns.
• Cost per round formatter for number fields: "$0.45 per round", "$0.45/rd" or "$449.99 ($0.45 per round)". The round count comes from the title, another text field or a number field.
• Firearm Specs for Commerce submodule: the same formatter for Drupal Commerce price fields, with the round count from the variation or product title.
• Barrel lengths in inches, centimeters or millimeters; optional links from caliber names to their price comparison pages (off by default).
• A firearm_specs() Twig function and a firearm_specs.parser service.
• A settings page where you can try the parser on any title.

Requirements

Drupal 10.3 or 11, PHP 8.1+. The gunsnprices/gunsnprices library (MIT, data CC BY 4.0) is installed by Composer:

composer require drupal/firearm_specs

The Commerce submodule needs Drupal Commerce 3.
