Better than simunition

Review by LPD854

We bought 4 of these to conduct active shooter training. Unlike simunitons, you can use standard AR-15 magazines and upper receivers with these kits. All you have to do is replace the bolt carrier group and your ready to go. They feed very well and out of about 500 rounds, we only experienced 2 malfunctions which could have been contributed to operator error.
