OK the quad rail arrived today --
out of the box it looks pretty good.
it does have an aluminum barrel nut.
the attaching pins for the rails look like their made of hardened brass?--LOL!!
i guess that don't matter much cause their threaded into the aluminum!
the rails themselves look strong enough and well made , they weigh in at around 15oz i would guess. the rails look to be reasonably well finished. just like the middie FF rails i put on the 16" 9mm carbine i built last year.
the rails are however "seconds" or 'blems" as the T-marks are not straight on the top and bottom rails--however the covered rails are arrow straight-?- typical!-LOL!
not a deal killer but they should have said "seconds" --but for the price i'll not complain. one trip into the bush and the off numbers will be covered in dust, oil, mud, residue and so on anyway. as there going on my scout rifle concept 16" 1-7" build. which is a brush gun of sorts.
sort of cheap looking plastic covers --but hey? who really expects covers at all at $50 for a rifle length free float quad rail.
had SMG just listed them as cosmetic blemished i wouldn't have anything to gripe about--
