I bought a set from Accuracy Sytems, who also make the port kit I used. Came with two; the instructions said try two, then remove one if the bolt doesn't lock back on an empty mag.
The original scope, a Hawke Endurance(!) 2-7 was fine for a few shots, then jumped impact to someplace else. Readjusted, rinse, repeat. The SS in "Horn" rings stayed put. Had a moment of doubt about the whole deal until I puzzled that out. Now I really like the oogly little spud. The buffers were installed after the fact, BTW. Accuracy seems about like the Springfield Saint I had a while back, and which I never cared for all that much. Different strokes.
I like the way it takes down too. Yank the trigger guard back and it just falls apart. Take the whole trigger group out, hose it out, lube it a bit and it's good. Gas system couldn't be much simpler. My reloads are with TAC to keep the crud to a minimum.
Paid something over $900, from Oakland Guns in AR. Found extra mags at CDNN.
