    "INCREDIBLE KIT. So keep in mind you DO in fact need to buy a piston head along with this kit, but it's like 13 dollars so that matters none at all. I put this kit in a WELLFIRE SR-2 MB13D, and the results are perfect. The instalation is simple, just make sure the metal spring guide inside of the aluminum spring guide is removed so your spring can get pulled all the way back.
    With .40 gram bb's stock, the MB13D shot those around 300 fps, a very slow and drawn out shot. With this kit, the .40 gram bb's shoot around 380-400ish fps. This improved my range heavily and the shot arrives at the target in a much shorter time.
    The only thing that became less simple was drawing back the bolt. An SP70 is big spring. So pulling that back became more difficult. Is it hard? No lol. It just takes a little more umpfh.
    10/10 would buy again. BUY THIS KIT!

    "Installed this kit into my TSD SD96. The hardest part was getting the spring into the cylinder. Standard 7mm springs are about 19 inches leaving only about half the piston sticking out. This Spring is a 9mm and was 23 inches long and none of the piston was in the cylinder while it was on the spring. After I got it in it was true to the descrption. *Side Note* After about 10 mags the spring settled into the average 19~20 inch range.

    It does fit
    525 fps consistently
    Easy bolt pull
    Very quiet, almost as quiet as original parts

    Have to buy a piston head separately, not much of a con I just thought a "Kit" would include everything.

    Very much worth the money and I will be buying more Angel Custom Parts on Payday.
