Understanding the Importance of the O Ring
When I first started using my Remington 1100, I quickly learned that the O ring plays a crucial role in the firearm’s performance. This small but vital component helps create a seal that ensures gas operates the action efficiently. Without a properly functioning O ring, I noticed issues with cycling and reliability.
