Also...the better AR pistols use a op-rod rather than Direct Gas Impingement
So they tend to be pretty reliable...and the muzzle flash can be impressive
I have toyed with the idea of getting a Kel-Tec and putting a Noveske brake on it...just because I can
If I don't like it I can always sell it to Brian :-)
( I break in all his new guns)
Maybe Delphi's problem was his (Wolf) ammo :-)
