Hello,
as for the ul the previous poster did mention all , a104,105,106 or hyprcharged 105 etc ...depending also if it fits on the weapon
As for the L version you can look up in ah for the Shear Series (e.g. XR70) etc...
if you need most power (e.g. for events etc) you can also check the hotfoot amps
you can also add them with your weapon on entropiawiki.com weapon compare v2 to see the final results..
