"So far so good. I have used it for one day, so idk about longevity yet.

Installed into my SR-2. Stock I was getting 350 FPS using 0.3g's, now with the upgrade I'm shooting at 430 FPS with 0.3g's. I can now shoot farther, flatter, and with less drift, and people can now feel those long range shots!

Cons: Shooting and cocking is a bit louder now since you have metal rubbing on metal, but thats to be expected. A homemade foam suppressor can bring the noise back down to stock levels.

FYI spring is for 11mm pistons like the stock SR-2 has, NOT 13mm. Also it is about an inch longer than the stock spring, so it will take a bit of squeezing it get the bolt back together.
