This will NOT stabilize in a 1:8", 1:9" twist barrel or slower! Priced per 50 rounds.Ĭarbine or pistol length gas system (will not cycle in mid-length or rifle length gas system)ġ:7" twist barrel or faster (1:6.5, 1:6"). Rifle specifications to run this cycling 223/5.56 ammo!!! This ammo is designed for the AR-15 platform. (Also try our standard 55 grain SP SUBSONIC- $99.50 per 100 rounds, Website link for ordering: 55 grain SP SUBSONIC) (Website link for ordering: 223/ 5.56 cycling SUBSONIC, 112 grain Expanding) What you have to do to make the gun work with subs renders it unfit for normal ammo, and 5.56 subs offer very little if. The loudest sound is the action cycling!!! Priced per 50 rounds. The bullet is a 112 grain EXPANDING subsonic lead core, copper jacket projectile. I like having options and some safety net. But after finding out 2 other nicely made 300 BLK AR gas pistons would not cycle subsonic + unsuppressed I felt it worth asking. These subs will work in any AR-15 rifle (16" barrel or shorter) with a pistol or carbine length gas system and 1:7" twist or faster barrel. Most likely if shooting subsonic Ill be suppressed so I am not overly worried about that. After multiple range trips and testing, I got a great working load. After years of working on this project, I finally got a working SUBSONIC load in 223/5.56 for cycling an AR-15!! I worked closely with a bullet manufacturer to tweak the bullets, and worked with many different powder and powder charges.

We have 5000 more bullets back in stock for our AR-15, cycling subsonic ammo.
