Maybe get Clayton Otto (near Empire Towers in GB) to order one in for you, likely be cheapest and he's a pretty good guy to deal with.
Or, maybe:
Clydes in Woodlawn area?
Bart's in GB?
Armory in Annapolis?
Dick's at Laurel?
The Remington 700 you saw is probably the "PSS". . . . long, wide, rounded forend, dual front studs, exaggerated palm swells . . . . $800 is probably about the going price.
The LTR is another 'police model', but much lighter, trimmer and a bit cheaper at $750 or so. Both are most commonly seen as .308's, though the LTR is available on .223 and the PSS can be had in 7mmRemMag & 300WinMag too.
The PSS and LTR are better built than the sporter versions and both usually shoot better than an MOA. My LTR .308 shoots to 1/2 moa with two different handloads - no work except fixing the 400# factory trigger setting and putting a Leupold 4.5-14 on it..
