I've seen nice Belgium BLRs go for up toward $800, the Japan made ones not quite so much (though they are fine rifles, too). As noted, Belgium BLRs were only offered in .243 and .308. I have one in .308, it's my hog-hunting rifle. I think I paid $600 for it about 4 years ago, but it was in absolutely mint condition. It's not mint anymore but it's not for sale anyway. Yeah spare mags are scarce and expensive. I quit bidding on one on GunBroker at $155 a few weeks ago but probably should have gone a little higher. I saw two at a gunshow last year that were patinaed, to put it kindly, and we're priced at $250 each.
