I have been shopping the left handed sales at CDNN sports a lot recently and now have a LH Turkish Hatsan "Magnum Supreme" 12ga semi auto shotgun & then I jumped in or on the discontinued Thompson Center Dimension LOC line of bolt action rifles in LH. So far have been able to get three bolts and four barrels along with three of their scope bridges. I first bought a complete left handed 30-06 Dimension rifle with a 22-250 barrel bolt mag and mag housing along with needed dedicated change out tools for $499.99 plus $9.99 delivered to my FFL. I have since acquired a Win 243 set and a 204 Ruger set. I have the AB & C bolt groups mag and mag housings and am looking for a LH D group bolt(300 Win mag & 7MM Rem mag IIRC)that I may or may not buy. BTW the LOC system barrels are usable on both left or right hand LOC receivers. I am looking for the rare(evidently)223/5.56 Dimensions LOC barrel but not too sure about getting one any time soon. I still have the LH 223 Rem American from Ruger so not in a rush.
