I had not seen an ADM rifle in person before receiving the 18" Midnight Bronze SPR last week.
I had high hopes considering the quality parts that go into the rifle- stainless barrel, geissele trigger, SF war comp, ambi controls including bolt catch in the lower receiver, PRS Stock etc. If I could have designed an SPR this is about exactly what I would have built it with.
I came to the ADM also upon searching for modern SPR options and getting disappointed that more manufacturers ignore this type of build and don't offer SPR length rifles.
Overall the fit, finish, construction, aesthetics, feel, even the weight is all excellent. The Midnight bronze is gorgeous in person and looks amazing with black and FDE accessories. Its very durable so far in areas like mounts where metal contact causes wear.
I'm impressed how light the hand guard and receiver set are. Especially given all the ambi options and excellent tolerance and fitment on the receiver set. Radian is another favorite of mine but for the same features the ADM receiver set is much lighter weight. The 17" hand guard is surprisingly light as well. The PRS stock makes this a fast swinging gun, and a regular AR style stock would make this a relatively light SPR and balanced rifle.
I give this thing a 10/10 for quality, fit, finish, and overall cool factor. I own several $2000-$3000 AR's and would put this against any of them and is among my absolute top favorite rifles among my Triarcs, Noveske's, Radians etc.
