  *Bentz Chamber
  ^{*The Bentz chamber is a match-type chamber for semi-autos.  It is not as tight as a true, minimum-spec match chamber, but is much tighter than a sporter chamber.  You will see much better accuracy with standard ammunition (in the 1000-1400 FPS range).  Because of these tighter dimensions, however, we do not recommend the use of CCI® Stinger® or similar long-case, hyper-velocity ammunition.}
