On another note, one of my buddies from my weapon manipulation shooting classes has been interested in getting into airsoft to supplement his RS training (well that, and he's had a lot of fun at our last few private games ). He asked that we build him an AR similar to his RS AR15. We picked up a LM4 this evening from AEX (Torrance, CA) and I worked on it this evening. He supplied me with a spare RS Troy 13" Battle Rail he had. I installed that and then cut down and modded the OEM front sight post to be a low profile gas block (old school style).
In retrospect, while the RS Troy rail did go on, it certainly made me work for it. Kinda like what I experienced with the Midwest Industries rail, the threading on the upper receiver was different enough from the RS spec, that the new barrel nut essentially acted as a die and recut the threads of the upper as it went on. It was a surprising amount of effort. It's now on there, but it wasn't 100% drop in with no problems. Anyone else experience this with their own RS rails?
This is the exact build that i always want to do to a LM4 when i get one soon. That Troy TRX rail looks great with the LM4.
