Phaedrus...I bought a complete Swensen slide from Midway for the Venom as they were factory machined for the Venom and a couple of others, but at the time did not have one for the Trijicon.... I sent the original slide to be cut for the RMR (the non adjustable one)... I like the way Battle Werx machines the locating posts and then threads through the stud... the front to rear clearance is outstandingly precise...they were the most reasonable of those I looked at, and after watching the video of the CNC work, decided on them... regards
