Thanks for all of the info guys

jjpeters4:
Is there a more powerful ram that can be installed into an npxl?

JohnInFbg:
I had seen a lot of posts on converting a Browning Leverage (exact same rifle as Xisico XS46U) from spring to gas cylinder, and noted Mike Melick had done these conversions.  I found his web site and it noted he no longer did the conversions.  I e-mailed Mike about doing the conversion, and his response was: "If you want to double cocking effort and get the same velocity out of it use the medium crosman ram".  His suggestion was to stay with the spring, add a top hat, tighten up the guide to remove the vibration, and add JM tar.

You'll need to remove the wire spring and guide from the QB57.

Easiest to install the gas spring with the body forward. You will need some spacing on the end of the gas spring. Maybe a short stack of washers if you have no lathe to make one. You can use a screw to hold the spacer/washers in place. The screw should not be too long as the gas valve is at the bottom of the hole and you don't want to release any pressure.
