Did I miss out?

Hello all, I saw an Echelon at my LGS, it is a 4.5F with Threaded Barrel with Gear up Package (5 mags and a bag). It's being sold for $700. I saw an Echelon package without the threaded barrel during Black Friday for $550 and I hate that I didn't check for a threaded barrel one.

Anyways, is that a good price? Or should I wait longer? Thanks.
