Angel Custom Advanced Precision Airsoft APS / APS2 / Type 96 / M99 500 FPS SP170 Tune Up Kit

"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!

"I would like to know if it is compatible with the APS APM40A3 rifle?

"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.

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

Cons:
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.

"Great overall quality but it does not properly work with a cyma M24. The kit fits but the spring is way, way too heavy for the rifle and won’t always cock. No piston heads for this kit work in the Cyma either due to it having a bore-up cylinder. This will work with a Snow Wolf M24, but beware the spring may be too strong.

"In regards to the snow wolf m24 this kit somewhat works. I don't know what was going on but when the spring guide was installed it wouldn't work, but other than that it is a nice kit but as for the snow wolf m24 it doesn't fit the greatest.
