I picked this up thinking I might go this route instead of the King Arms - but I guess I am just too stuck on my King Arms. So this had a few rounds to chrono it - was over 400fps (do not remember the actual readings) so would need to be downgraded some.
Comes with 4 -90rd mags (plus the stupid hicap they send with it)
Put an FNC muzzle device to try and make it look close to the proper length barrel.
Just trying to get what I have in it back out - so $285 plus shipping.
