Sprinco has extensively tested this setup and have concluded that it works great with the VLTOR A5 stock setup. It also helps you to easily identify which power spring you have in your AR-15 if you have a habit of changing your setup constantly.
Note: In an effort to help our customers save on shipping costs, these springs may be shipped without the plastic tube.

Take a moment and ask yourself, “What does the greatest spring in the universe look like?” Whatever image you have in your mind, it’s wrong. Unless of course you were thinking of the Sprinco M16 Buffer Spring. Is it from the future? Secret alien technology? I’m not sure yet, test are inconclusive. What I can tell you though is I can hold a half inch grouping on a target 5 miles away now. Too good to be true you say? Find out for yourself I guess.
