Useful assortment

Tons of sizes and all well-made. Great value for repairs and DIY work.

Needed a buffer tube retainer pin spring... they sell for about 89 cents online with over $8 shipping! Didn't want to pay 10 times the amount of a single little spring for shipping. Thought we would try this kit. One of the sizes worked PERFECTLY! Now I still have 299 springs in a nice kit form for future needs. My only complaint is that someone at Amazon's shipping department put the shipping label over the kit's spring inventory label. We had to gently peel it off ASAP so that the inventory label of the contents wouldn't be destroyed. After removing the shipping it left sticky glue on the inventory label... We put clear packing tape over the inventory label to cover the sticky glue. Why didn't Amazon just ship this in a cardboard box with a label we'll never know?

Weak springs. Only one would I consider slightly with good tension.

I thought the diameter of the springs would be larger
