The Lynx has the charging handle on the RH side where as the Cheetah is on the left. I consider that more desirable in an SBS. IIRC when Tromix was doing conversions, the the LH handle was an option. I've got a Cheetah coming in for evaluation.
I wonder if the Trench 12 has had any mods to the gas system, port enlarged etc.
