Yup, Remington M597 LSS.
One of the first models that came with that really troublesome plastic magazine. Got two metal ones in exchange for the plastic one when I sent it back to Remington.
I've got roughly 7000+ rounds through it so far. The bolt has a tear in the metal body now and I just repaired the trigger sear spring that popped off a month or two ago.
I dunno about the newer one's but don't overtighten the bolt guide rods at all, it'll lead to more jams. Also, stay away from the 30 rounds mags. Other than than that after I broke it in (2000 or so rounds) it feeds flawlessly.
