very solid, with good weight. the fit is almost perfect with the magpul grip. it's only an M4 (sorry, M6) but it's just right. one of the most perfect feeling airsoft weapon i've seen in a while. it is shooting a little hot at 375fps with .20's but i hope it will go down a bit in the next few months when i will be attending the next Op.
great ROF with 11.1 lipo
very consistent FPS (over 10-15 shots, only went up & down 1fps!)
replica of a gun made in MARYLAND.
very consistant BB stream.
bolt cover doesn't close anymore because it is worn just enough.
loud, but that's not bad to everyone.
the battery wires will not let you push the stock all the way in, only to 2nd click
