I recently switched over from the SAGE EBR chassis system to the new Troy MCS for my SOCOM 16. My S16 never worked right from the factory, continually jamming and eating bad parts. When it did actually go bang, accuracy was only 3-4" at 100yds. I know it's not a target rifle but it could do better.
The SAGE, with the addition several USGI parts, was much better. Right around MOA with good ammo.
The Troy is lighter and more streamlined. The most important improvement though by far is the continuous rail that is MUCH more optic and iron sight friendly than the SAGE. Although these pics do not show it, there are Troy iron sights mounted on it now.
Before anybody starts, the M203 pics were for chits and giggles.
And just to prove
I haven't been here in awhile, this should be in Custom Builds as it is NOT an AR. Doh!
