Since they are aluminum, they are much more durable than plastic ones.In addition to these 7.62x39, I have 30-06, .308, .223, 9mm, and 40s/w.They are all the correct sizes and great for saving stress on your firing pin and for practicing loading, unloading, and clearing malfunctions.
Good snap caps.
A-ZOOM the only snap caps I buy!
Great quality, tested one with 50 firing pin strikes and they cycle flawlessly in my Yugoslavian M59/66.
They work great and the price was cheapest I’ve found.
It protects the firing pin quite well for dry fires.
Usually a quality dummy round, I've used A-Zooms for different weapons over the years and like the distinctive red coloring.
But these don't work in SKS clips at all.
The fit at the base is too tight.
They can still be used to load the magazine and dry firing.
