**Title:** Firing a Pin Fire Gun in Slow Motion (implied, not explicitly stated)
**Summary:**
* Host Gavin, a former Army member, compares firing a massive 50 Cal rifle to a tiny Pin Fire Gun (not technically a firearm).
* The Pin Fire Gun is incredibly small, with a bullet smaller than a standard American quarter.
* Gavin struggles to fire the tiny gun due to its size and his sweaty hands.
* Despite initial misses, he successfully hits a target, showcasing the gun's surprising power in slow-motion footage.
* The team uses a macro lens to capture the gun's mechanics up close, highlighting its tiny scale.
* The video ends with reflections on the fun of firing the tiny gun, warnings about handling such devices safely, and promotions for their social media channels.
Here are the key facts extracted from the text, excluding opinions, with each fact numbered and presented in short sentences:
1. The host, Gavin, was in the Army for about seven years.
2. Before this video, they fired a 50 Cal rifle, which is 12.7mm in size.
3. The 50 Cal rifle is significantly larger than the pin fire gun used in this video (2mm).
4. The pin fire gun is technically not a firearm because it uses pin fire, not rimfire.
5. The pin fire gun is small enough to be worn as a keyring or necklace.
6. The gun's rounds are approximately 2mm in size, with about 20 rounds in a tiny bulb.
7. For size comparison, an American quarter is thicker than the distance between the gun's foresight and barrel edge (~1mm).
8. The pin fire gun does not have a safety mechanism.
9. To reload, the user must crack the barrel, use a push rod to eject the spent round, and then insert a new round.
10. Spent rounds have visible black carbon buildup.
11. New, unfired rounds have a distinct appearance with a small ball bullet on the end.
12. The host fired the pin fire gun at a target, achieving a hit from approximately 25 meters.
13. The gun's firing process was examined frame-by-frame using slow-motion footage.
14. A macro lens (Canon macro lens with a PL mount) was adapted for use with a Phantom camera to capture close-up shots.
15. The host had to be careful when handling the gun due to its small size and sensitivity to movement.
16. The video's editing process involved considering adding sounds from the 50 Cal video to the macro shots for contrast.
