Many More but those two are my favorites.
Maten has 18″ KAK mid gas 1:10 bbl with SWFA SS 3-15, and DMR trigger.
SPR/MK12 variant has 18″ Rifle Gas 1:17 SPR WOA barrel SWFA SS 3-9, SSA-E trigger and freshly updated to BCM KMR-A Rail and Minimalist Stock to shed some weight from that heavy 18″ barrel.
