My Buying Guides on Should An Ar 15 Cycle Dummy Rounds
When I first started working with my AR-15, I quickly realized that understanding how dummy rounds interact with the rifle’s cycling was crucial. Whether you’re training, testing, or just maintaining your firearm, knowing if your AR-15 should cycle dummy rounds can make a big difference. Here’s what I’ve learned from my experience.
What Are Dummy Rounds and Why Use Them?
Dummy rounds are inert cartridges that contain no primer or powder. I use them for dry firing practice, function testing, and training without the risk of accidental discharge. They help simulate the feeding and ejection process without live ammunition, which is great for safely checking if my AR-15 cycles properly.
Should My AR-15 Cycle Dummy Rounds?
In my experience, a properly functioning AR-15 should cycle dummy rounds just like live rounds. This means the bolt should strip the dummy round from the magazine, chamber it, and then eject it smoothly. If it doesn’t cycle dummy rounds, it might indicate issues with the magazine, ammunition dimensions, or the rifle’s gas and recoil systems.
Factors That Affect Cycling of Dummy Rounds
- Quality of Dummy Rounds: I found that not all dummy rounds are created equal. Cheap or poorly made dummies might have inconsistent dimensions, causing feeding or extraction problems.
- Magazine Compatibility: My AR-15 cycles dummy rounds best when using high-quality magazines designed for reliable feeding.
- Rifle Condition: Proper cleaning and maintenance are key. A dirty or worn rifle can struggle to cycle even live rounds, let alone dummy ones.
- Gas System Setup: If your AR-15 is adjustable or has a different gas system, it can impact cycling reliability with dummy rounds.
How I Test Dummy Round Cycling
To check if my AR-15 cycles dummy rounds, I load a magazine fully with dummy cartridges and manually cycle the charging handle. I watch and listen for smooth feeding and ejection. Any hesitation or failure to chamber usually means I need to inspect the dummy rounds or rifle components.
What to Do If Dummy Rounds Don’t Cycle
If I encounter issues, I start by trying different dummy rounds or magazines to isolate the problem. Sometimes resizing or lubricating dummy rounds helps. I also ensure my rifle is clean and properly lubricated. If problems persist, consulting a gunsmith or reviewing the rifle’s gas settings might be necessary.
Final Thoughts
From my experience, yes—the AR-15 should cycle dummy rounds smoothly as part of proper function testing and training. Investing in quality dummy rounds and maintaining your rifle will make this process much easier and safer. It’s a simple way to get more familiar with your AR-15 without live fire, and I highly recommend it for all AR owners.
