History: 
    The MG42 appeared in 1941 to supplement the MG34, though not totally replace it.  The MG42 was easier and faster to build than the MG34, with nearly twice the rate of fire.  The MG42, due to its looser design parameters could ingest higher volumes of foreign debris and continue to function.  Jamming was not a particular problem for the MG34 though.  The bolt was greatly simplified from an intricate twisting locking mechanism to a much more simple dual roller lock which both locked it to the barrel momentarily upon firing and held the firing pin retracted until the bolt was fully seated in the barrel.  Though the barrel removal is notable cool on the MG34, it is faster on the '42, reducing time from roughly 7 seconds to 5 for an experienced crew.  There was also less chance of getting dirt into the receiver with the MG42 swap.  Due to the reduced tightness of the MG42, and the recoil effect of the higher rate of fire, the accuracy was largely reduced.  The MG34 was a beautiful show off display of pre-war arms; the MG42 was a wartime functional replacement.  Imagine the U.S. in a big war...  it's doubtful we'd mass produce F-22s for long. 
    In short...  The MG42 could be made faster and more easily by unskilled (and forced) labor.  It jammed slightly less per round (but more often over seconds of firing duration- especially with later steel cased ammo).  The barrel swap is improved.  It could be stripped and operated by Volksturm (more simple).  It was less accurate, but projectile density over area remained the same (twice as many rounds over twice as large an area).  The MG34 remained in service until the end of the war and as the exclusive internal tank armament in the modified panzer derivative.
  The MG42 is still in service today as the MG3 (among several others), chambered for NATO 7.62.

Gas Simulators: 

 

    This is known in reenacting circles as a 'gas gun'. For those not familiar with the term it denotes a unit which mixes a fuel such as propane and oxygen into a combustion chamber. A small computer opens and closes the gas solenoids and times an ignition circuit which fires a spark plug inside the chamber. This type of simulator is safer than blanks, as no burning powder is expelled. NOTHING CAN BE LOADED INTO THE CHAMBER OR EXPELLED FROM THIS UNIT. This makes it perfect for reenactments, living history displays, and even movies.  I no longer build gas simulators as it is very time intensive and they can be quite temperamental.  I am still glad to answer questions about them and assist the guys who already bought them from me (years ago).  I do offer a small manual that helps with the construction of one for $5.  This manual is explained and available here.  (Still part of my website.)
