I went down to Spectrum Tactical in Rock Hill to see the machinist about getting some work done. He makes a lot of tubes for some well known "solvent trap" vendors. Anyway he's also a 02/07 SOT. He demo'd one of the .22 cans he sells . All stainless steel construction. Well made clipped stainless cones. Basically what my Spectre 2 is at about half the price and quieter. Went out and shot it and it was stupid quiet. $175.
