"I love this spring!!! i'm shooting 509 FPS in my M4 and i'm sure that i don't have the best air seal , i still have some fine tuning to do but i am very happy with this spring!
Works AMAZING in my SVD!
If you need a good spring for a high powered sniper.... GO FOR IT!
"Great spring for 15$. HOWEVER. This spring gives you an average output of about 673 fps. Which is a huge safety issue. Playing with this is really for experienced players only. I'm not kidding here. I play with a minimum 100 feet engagement rule. Within 100 feet it really could do some damage. But with the correct clothing (i.e. vest, bdus, facemask, etc.) It's not too bad. IT WILL MAKE 'EM CALL THEIR HITS!!
Btw to have this spring in your gearbox, you need to make it ready to pull it...
I've got a Prometheus High torque steel gear set, 6.03 590mm Prometheus tightbore, a G&P hard piston, angel custom hard 70 bucking with a polarstar spacer, and a G&P m180 satan motor. Everything else was left stock (Had a g&p 8mm gearbox wired to deans. Shimmed and tuned well).
Overall a great spring... just make sure you know how to use it... and safely use it!
