Now, photos of how the little bundle of joy arrived at my house:
Field stripping it revealed the plastic parts to be nearly identical to the Steyr AUG stock and trigger pack. The trigger pack is a 3/4 scale version of the Steyr, right down to the "drop safety" that locks the sear in the event the rifle is dropped squarely on the muzzle. I hope FN paid Steyr for the design, or there could be severe legal problems here.
My initial review is that this is an amazing little rifle (except in Michigan, where it's an amazing big handgun). First, it's totally amidextrous, except for the sight adjustments. Top feed, bottom eject, charging handle, mag release, and the safety is a horizontal disk at the bottom of the AUG-like trigger. The reflex sight is nice, with an optical bullseye reticle and tritium-illuminated posts at 3, 6, and 9 o'clock. There is also a large empty area in the stock behind the magazine. I don't know what it's for, but it has rails and grooves already molded in.
So far, my only real reservation is the very narrow viewing angle of the sight, which does not make for easy snap-shooting.
Second, the weapon is lacking accessories, like more 50-round mags (I bought four a year ago on the hope that my FN ship would come in some day). I can put on Picatinny rails on the top and two sides of receiver. I might wind up with an Eotech holographic site on the left side, and a light on the right.
And if I can ever track down the rumor that Michigan will allow the BATFE to issue tax stamps if the proper number of chickens are sacrificed, I may plunk down $5 for an "any-other-firearm" stamp, and $250 for the 8-inch barrel of the SMG.
I'll post more as soon as I can track down some 5.7x28 ammo.
