I have a used Noveske kx3 "Flaming Pig" for sale for $110. It has a 1/2 x 28 thread pitch (AR-15). If interested let me know by call/text at (210) 867-3246, Thanks.
It has been sold, I love these... I decided to trade one of my 10.5" AR pistols and the guy didn't have cash to add on his end so that was one of the things that was taken off to even the trade.
