Important parts to have for your build or just as a spare - Guntec USA AR-15 Lost Parts Kit

The name alone says it all. No matter how careful you think you are you're bound to drop something. Im glad I bought this kit. Right off the bat I dropped one of the detent pins and was on my knees for 20 mins looking for it. Impossible to find on my black and grey speckled garage floor. Gave up the hunt because I had another pin in the kit I bought and was able to countinue with my build. I hope it will show up eventually. But the kit was a lifesaver..going to buy another lost kit. �
