Looking to put together an RT/X-Valve mag and read a bit on Hill's efficiency mod. Haven't seen much since the initial couple of threads on design and looking for testers. What's the consensus on these?

pros and cons to them. on mine it rendered the lvl 10 almost useless because of the higher pressure required to operate the valve but I do get 8 140rd pods with a full hopper to a full 68/4500.

just make sure your hopper batteries stay maintained

well, if you are going with the RT, then it will use up more air. IMO, the efficiency mod isn't worth it, especially if you can't use the L10. the only thing you could really do is have a good paint to bore match, with good single tubed barrels.

I run a efficiency mod on my egomag and have no problem tuning the lvl10.

Dunno. I've tried everything to get the lvl10 to work
