A few years ago I had a friend with a machine shop modify this Tactical Trilogy to be mag-fed. He took the body of a RAP4 T-68 (now renamed Firestorm) pistol, liberted the magazine mount, and then milled the feedneck off the Trilogy to fit the mag mount. Two screws hold it in place. I never got around to having it duracoated, so some machining marks are visible from the customization- despite my best efforts with a Sharpie.
Works great- have never had a chop. Only fielded it once or twice - mostly just plinked in the back yard. With a quiet barrel and some tweaks to the timing you could have a near-silent sniper.

- I have a baggie somewhere with the stock bolt, reg, and other bits, that I will throw in if I can find it.
