## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Perfect instructional aid or use for dry firing drills!
  

*by C***E on Reviewed in the United States on June 5, 2015*

Great product! Quality construction!  I am an NRA Firearms Instructor and use snap caps in my classes for safety.  When teaching a large group using different firearms, it saves me a ton of time to have snap caps in different colors, according to their caliber.The Ultimate Arms Gear snap caps are made of metal with colored plastic bullets.  (not weak aluminum)  These snap caps can stand up to the abuse of teaching how to clear jams.  (such as stove pipe jams )Highly recommended!!!

    Very happy with this product
  

*by M***O on Reviewed in the United States on November 30, 2015*

Very happy with this product. Great for teaching those unfamiliar with semi automatic firearms, such as Glock Pistols. The only issue I have is that I wished they were a little heavier so as to match the weight of a 115 grain bullet. Very solid product, I will be buying other calibers.

### ⭐⭐⭐⭐⭐ 







  
  
    Great company, fast shipping
  

*by J***E on Reviewed in the United States on November 16, 2015*

I bought these through American Tactical.  Great company, fast shipping.  These work well in my handgun and will be just what I need for practice, especially the "surprise" dud, round to prepare for mis-fires, etc.
