Posted this on another forum a few months back, hope it helps...
I got mine here in the EE, came unfired in the factory packaging with manual, Knoxx stock manual, rifle, one 10 round factory magazine, chamber brush, and of course the rifle. The big selling feature of this gun is its ability to use AR15 mags. The data stamp indicates both .223 and 5.56mm
finish appears to be some kind of blue. it looks good, but seems to scratch easily. I already put a nice scratch on the left side of the receiver. If it gets too dinged up, I think Ill get it parkerized.
Overall lenght with the stock collapsed is 36'', extended 38.5''. Lenght of pull varies because of the 5 position stock between 12.5'' and 15''
synthetic and wood stocks are also an option. sorry bout the smaller size, took them off google.
870 20 gauge stocks are compatible with this, and the 7600/760/7400/740 rifles
i think its 'survival arms' makes a railed forend for the rifle for mounting lights or whatever, but they are steep at 250 bucks US. but i think a small surefire E1E mounted on the left would make a good SHTF gun.
Barrel is a 1:9'' twist, and 16 3/4'' inch when measured from the bolt face to the muzzle as per the CFC approved method.
The sights on my rifle are the standard remington factory rifle sights, identical to what comes on 700 ADL's and 597's. The factory sights have a very short radius, with only 10'' between the front and rear sight. It makes for poor accuracy, but they are quick to pick up.
A ghost ring rear sight is availible as an option, and I think I would prefer it. the rifle is tapped for a scope base, but none was included.
brownells has the optic mount for 62 bucks

the correct weaver base for scope mounting is the #93 top mount.
I tried 7 different mags, old CF thermold, unmarked made in korea, C Products, Adventure Line, PMAG, LAR 10 round pistol mags, and of course the factory mag. All the mags fed well and dropped free when the release was pressed except the old CF thermold which sometimes needed a light shake to fall out.
Ammo tried was remington bulk, american eagle and sellier and bellot. All fed reliably, as long as you dont baby the action and short stroke. Speaking of the action, the tube retracts when pumped, not like an 870, and the stroke lenght of the action is 4 inches . The front swivel is attached to this tube, so if you shoot with a sling through your arm you might find it irritating.

ergonomically, the gun feels good and shoulders well. the sights pick up quickly. The action release and safety placement are identical to an 870. The mag release however, is way to far forward. im an inch and a half shy of reaching it while holding the grip.

good
not so good
There is a plastic action cover that slides back and forth with the bolt. It seems flimsy, but hasnt caused any problems in the 200 or so rounds ive fired so far. Doesnt look hard to remove, but as long as it doesnt bugger up, it will stay.
we spent the evening shooting balloons and various distances from 25-100 yards, the gun handles fast and accuracy is better than the mini14 I owned last fall. Im going to throw some glass on it eventually and try a few other brands of ammo before I report back. From what ive read on the forums, 2'' at 100 yards isnt a problem.
brass ejects with enough clearance that thedutchess liked shooting it, so while the safety and mag are right handed, shooting and working the action is not a problem for a left handed user.
