Took em' 50 years, and even completely different alloys, but we did finally get the E4/E6 right.
Almost 2 lbs lighter than the lightest M240 variant. And at 500-odd RPM, your ammo belts will last a lot longer too.
U.S. Ord took the M60E and made it what it should have been in the first place. Overall layout and operating principle is the same old M60, but done right. And actually reinstated all the good features that the inspiring rifles and GMPG's that were borrowed from , like the ability to close the feed tray/top-cover on a forward or rearward bolt, glove-less quick change barrels with a BREN-like barrel carry handle, and most all parts re-worked to be only one-way assembly, or actually reversible/directionless like the gas-piston.
And U.S. Ord also has .mil contracts for MAG58's-M240's, and for U.S. M2's, so they know the strengths and weaknesses of each inside and out.
Were I so lucky to have a choice, I'd want an M60E over a 240.
