Any review on TU 125 spring

[bryan015]

ano po bang fps ang kayang ibigay nito sa mp5a4 ko?

[gaMay®]

380-400 fps. TU 125 is somewhere guarder sp110-120.

[bryan015]

hina din pala. kla ko kcing lkas ng PDI 190%... ano kayang magandang TU spring na aabot sa 430-440fps..?

TU 145 maybe. But sir, you must consider that changing into higher rated spring will also need some parts to be replaced like PB, Gears, etc. . .

In reaching high fps di lang naman spring ang focus.

Try mo element 135. Around 300 -350 lang each.

[bryan015]

ah ganun po ba... kaka palit pa lng po ng metal bushing.. jg red metal pb.. allum ph w/ bearing.. kung lalagyan ko po ba ng element 135 d po ba bbigay ung gearbox?

Basta good ang compression di naman sir masisira ang gb. Element 135's stiffness is just average. . .

pwede mo din pahabain barrel mo, ang element m125 nakuha pa namin ng 480 max sa ak length. 145 spring will reach 480+ kahit maikli barrel.

[gaMay®]

Yes, barrel length is also a big factor producing higher fps. As i have stated sir bryan, wag lang po kayo sa pring mag-focus.

I've been using a TU 125 for several months now. I was able to get an average of 430 fps when I used it with my G3. Except for the metal bushings, everything in the gearbox is stock.

I recently bought a TU 130 spring, was surprised to learn that my stock battery (8.4v 1500mah nicad) could be used to crank it. I don't know the fps reading but I would say it is more than an sp120 but not over a PDI 190.
