 Product Description

The Lightning Banjo is an upgrade part for the Fusion Engine that dramatically improves the efficiency of the FE platform by 25 to 90% more shots! Works with V2 Gen 3 and also V2 Gen2/ and Gen 1 but will require modification. Will work on M249 platforms giving the saw gunners even greater Air Efficiency.


Q: How does the Lightning Banjo work?

A: The Lightning Banjo re-routes the air pressure left from opening the poppet valve out of the banjo itself rather than back through the long hose and back through the solenoid exhaust.  This relieves the pressure that the poppet spring must overcome in order to close the poppet.  In turn, this closes the poppet much faster than with a stock banjo and avoids wasted air being released after the bb has left the barrel.  The result is air savings of nearly 40 to 90 percent.
Q: Do I need to change any FCU settings?
A: For most setups, FCU changes are unnecessary, though very minor changes of a few dP may yeild minor improvements.  For extreme low PSI configurations increasing the dP may be needed.

  1. Yes, it works

    Posted by Shamo on 24th Sep 2016

    Installed it in my M240 and Stoner LMG, both used as high ROF support.
    The difference is stunning! Air consumption reduced by 30-40% even at the most consuming settings makes this item a cost-benefit-champion. Go get it!

    If you're looking for a product on the cheap to decrease your air consumption by up to 90%, then buy this right now. It works so well, and I get a lot more shots per tank than i did without the S2 Banjo. in my opinion, this is a must have for any Polarstar user.
