jse has some stuff in , troy mags, uppers, some lowers, barrels and all kind of hard to find goodies.
mostly @ MSRP or lower.
they have a $70 7.62x39 YHM upper, and a $100 DPMS 308 upper and some of those cav arms nylon lowers.
i was lucky and got ONE bushmaster lower for $135--
if your needing ar stuff this is the place to look for in stock stuff.
