    High quality spring. Maintain their tension well. SP rated, so will give around 120mps with .25g bbs, rather than M120 springs which are 120mps measured with .20g bbs.

  21. Mike R. (verified owner)

    exactly what i needed to get the power output i desired.

  22. Justin (verified owner)

    Works great. Right after fitting I got around 395-400fps on 0.20s, although I understand with more use that might increase.

    It’s a simple spring and it works as advertised
