PLEASE READ the entire AR-15 rifle specs needed for this ammunition to shoot and cycle properly in your AR-15 rifle.
Now Available! After almost 3 years of testing and experimenting, we are now producing cycling subsonic ammunition for the AR-15 platform. The ammunition is loaded with a full custom 112 grain HP bullet, new brass cases and our proprietary load for a cycling subsonic round in the AR-15 platform. We will be making runs of 10,000 rounds at a time and we have 50,000 bullets available to load currently. We will be loading ammo as fast as possible, and will be shipping ammo orders in the order they are received. Depending on when an order is placed, please allow for 1-2 weeks for delivery. Priced per 50 rounds.
Priced per 50 rounds.
The AR-15 rifle specs MUST have:
- Carbine or pistol length gas system (not intended to cycle in mid-length or rifle length gas system)
- MUST have 1:7″ twist barrel or faster (1:6.5, 1:6″). This will NOT stabilize in a 1:8″, 1:9″, 1:10″ twist barrel or slower!
- Must be shot suppressed! (we recommend shooting un-suppressed first to confirm bullet stability in your rifle)
- 16″ barrel or shorter!
- MUST have standard or light weight buffer and spring. If you have an H1, H2, H3, or H4 buffer/spring set up, it will not cycle. These have too much spring tension and too much added weight to cycle the bolt when shooting lower pressure subsonic ammunition. We will be offering a reduced spring and standard buffer for purchase if you have the H1, H2, H3, or H4 buffer/spring set up. (please contact us for ordering the light weight spring and buffer)
If you have the H1, H2, H3, or H4 set up, please order the Yellow Spring and standard 3.0 oz buffer (below) to install into the lower for proper cycling.

Make sure you do not have any added weights to your bolt carrier. I have used my standard 16″ carbine AR-15 (pictured below in the video) with 1:7″ twist barrel, and a 10.5″ pistol for my testing. Both have performed very well with this ammo. Priced per 50 rounds.
If you are unsure of your rifles’ specifications, consult your gunsmith or rifle manufacture for specifications on your rifle.
