S.T. Action Pro 223 Cal / 5.56 MM Dummy Rounds – Orange Safety Trainer Dummy Rounds, Reusable Dry Fire Training Ammunition (5-Pack) for Gun Owners - Veteran-Owned, Assembled in the USA

Good for practicing reloading and for learning how to recover from gun jamming.

These little things come in handy when I'm in the house and want to turn my bedroom into a gun range without my wife killing me lol. They cycle great and due to the orange tip I cant mistake them for live rounds. On the other hand if a blind person can shoot they'd definitely mistake these things because the weight and shell feel exactly the same. These are dummy rounds though and not snap caps so as you can see I've taken a hot glue gun and filled the primer hole turning these into snap caps. They run perfectly, I suggest you guys give it a try. As for durability I cant speak on that just yet because I just got them today and only cycled them a few time. I love them though!!!

Fits and cycles good. So far seems solid.

works good, only reason i have it 4 start is becusae it doesnt eject out as I expected even though its made with brass casing, the size to a 5.56 ammo is a bit off seems like due to the plastic pieces. So it doesnt grab as good when you pull out the charge handle. overall good item for training to reload, dry fire, etc.

I liked the fact that these are probably really close to the real ammo. specs. If you ever wanted to see what real rifle bullet is, you can see for yourself. You can also leave on of these inside a rifle to use as preventative maintenance.

They don't jam on my AR15 so I'm happy with the purchase.

Good practice rounds cycle good make sure your AR works.

These snap caps are only suited for manually feeding them into the chamber. So, if you have an action where you can repeatedly cock the hammer without having to eject the round in the process, they may work well. However, they did not cycle properly in my semi-auto rifle. When recycling the charging handle on the action with these rounds in the magazine, there were repeated jambs that defeated the purpose of the dry-run exercises for which I purchased them in the first place. While the orange tips afford positive identification of the dummy nature of the rounds, they are a bit too short for the task that I had in mind when I purchased them. I returned them promptly and quickly received the refund I requested.
