I have this spring installed in my G&G FS-51, and I finally was able to chrono it at a game yesterday. This spring, paired with stock G&G gearbox parts, a Systema cylinder head, a closed cylinder, a 469mm Prometheus TB, and a Systema piston head, was giving me 357 to 358 FPS with .25g BB's.
I used a joule/FPS calculator on Arnie's to calculate that 357-358 FPS with .25's is equivalent to 398 to 399 FPS with .20's.
This spring might not be broken in, since I have been sticking to semi-only for the most part, so that may be a factor in the high FPS for an M110.
Pros:
-Consistent FPS readings-_ There was only a 1 FPS difference.
-The relatively high FPS gave me a small range boost.
Cons:
-None.
