"Great upgrade part for your gun. Once you're in your mech box you will so how poor of quality your stock one is. I recommend upgrading this at the same time as installing a new spring. It's easier to only open up your mech box once, rather than a second time. Make sure to buy Evike's grease/oil kit for the bearings and seals. Save on shipping it all together!

"I bought this for my echo 1 stag arms m4 with a pdi 150%. Worked great and i took it out to check it out after using it several times only to find out that it doesnt look worn. Only problem that i had was a bad compression problem due to putting to much grease on the cylender and piston head. Its a great product and great for your wallet.
