"This so called "M110" spring is incredibly stiff and feels stronger than my stock M120. I originally bought this as a weaker spring replacement that would be easier to put in my AK's gearbox than the stock spring, and this DOES NOT serve well in that function. This M110 is significantly longer and as I said before, stiffer than my M120, and is a huge pain in the butt to get in he gearbox shell without itviolently popping out. Overall, I would not recommend this to anyone if you're wanting to downgrade your spring, it might work as an upgrade if you know how to do it.

"Great spring, works as expected. I ran it through the chrono with .25s on a high compression setup and got these numbers w/ .25s --- 348,349,351,349,348. Stock motor could pull this, i highly recommend it for instant fps upgrade.

"I have purchased 3 of these spring and have received mixed results. I first purchased this spring for my m249 as a slight increase over my m90 so my piston would keep up with the gears, i went from 320fps to 435fps. second I purchased this spring to do an upgrade for a friend, 350fps. third was my most amazing, i got this spring for my RPK which i planed on it shooting 350ish fps. i installed this and i am now getting 470fps. these springs are not good for precise upgrades. however, for how long I have used them they keep their power very well.

good spring, mixed results
