I've been scouring the internet for reviews on the Edgi SAP piston withoutany luck. I am hoping the weighted piston will address my joule drop issues. I lose about 0.3j when going from 0.32 to 0.48 bb's. Any input would be appreciated it.

What length barrel are you using?

In the experience of myself and a few friends, stay far away from the SAP unless you have an edgu cylinder. WASP is awesome, but I personally run an SCW piston.

I believe it's a 430mm. It is a JG pro. Specs below. Thanks.

Yea, that barrel is technically too long for .48g. 370mm is the ideal length. A tightbore will also increase fps if you're using the stock barrel.

With a weighted piston you can overcome that barrel length issue. As I use a similar setup with a 430mm barrel.

I get the most power on .48g bbs due to the WASP piston I'm using.

Thanks for the input. I will look into the Wasp as well.
