I bought 2 LMT a few years ago. I paid a premium for them (bought new from Questar) and I never had a problem. I'm very happy with my rifles. In the 3 last years prices for ar15 in general dropped, but is now going up again with the exchange rate. LMT are top tier brand but do not command a premium like KAC or noveske.
The problem with a MRP16 is that there is other good option for a lot less, so it'll be hard to sell it for a premium. If you want to buy it it's good news.....people's remember colt ar15 for 1000$ so are hesitant to pay a lot for an ar15 even if Colts are way more than 1000$ CAD now.
