AR-15 .223 / 5.56 Dryfire Plug - TRT Magazine Insert (3 Pack)

AR-15 .223 / 5.56 Dryfire Plug is a TRT training insert fitted directly into an empty magazine. It limits follower travel so the follower does not engage the bolt catch during dry-fire training.

With the insert installed, you can pull the charging handle fully rearward and release it without the bolt carrier being held open. Its profile lets the bolt carrier pass over the insert without feeding it from the magazine, making repeated manipulations and tap-rack drills easier.

Key features

• For the AR-15 platform: designed for .223 Rem / 5.56 NATO magazines.

• Full bolt carrier travel: allows a complete rearward movement without locking the action open.

• Repeatable dry fire: supports reload, malfunction-clearing and tap-rack drills.

• Magazine-mounted: stays inside the empty magazine and is not fed by the bolt carrier.

• 3-pack: lets you prepare several dedicated training magazines.

Training with Mantis

The Dryfire Plug is often used with training systems such as Mantis. It helps retain natural handling of the rifle and enables repeated drills without the bolt carrier locking open.

Safety notice: this product is a training aid and does not replace safe firearm handling practices. Before training, verify that the firearm and all magazines are unloaded and remove all live ammunition from the training area.
