The Invictus Practical AARM/S 8ighty-8ight is a sixteen-round shotshell caddy system based on the incredibly compact "8ight Plate" - equally suited to both the Quad-Load and Load-Two techniques - which attaches to one Tek-Lok, TMMS, ELS or MLS (sold separately) via a user-bendable Long Coupling Bar with serrated lock washers, 10-32 screws, and nyloc nuts - all in 18-8 stainless - for max torque, adjustment range and per-shell value
