Rated 5 out of 5 by from Excellent pricing I bought this to go in my emergency survival bag. So I have not used it.having been in the Military though I can say it is as described.Only wish it had optional caliber choices.

Rated 3 out of 5 by from Good price, But second set was incomplete The first kit I bought was complete. However, the second kit was missing the safety detent spring. Let me tell you. Finding a spring like that on a weekend is near impossible. You have to buy a whole spring kit to the tune of around $50.00. Just for a $3.00 spring.
