Will it work with a suppressor?

A

Answered by Jesse Sando, member, from OH, United States, on January 23, 2026

They work just fine in suppressed rifles, just make sure you buy the correct weight for your particular rifle. Probably an H2 or H3 weight depending on the gas system length (H2 for carbine/mid and H3 for carbine/pistol depending on how the rifle is gassed and dwell time)
