AR-15 magazine bottom metal for Remington 700?

Hey guys, I picked up a Remington 700 chambered in 300BLK - looking to take this thing to the next step. Anyone have access to bottom metal that accepts AR magazines in Canada?

Mixed reviews about this one but I have been thinking of it for my SPS. I have an uninstalled Atlasworx that uses AICS mags but they are expensive.

Hmmm. I just bought a .300 Blk as well, and I think that adaptor would be just the ticket. It's a fun little rifle, though a bit heavy for its size....

Anyone in Canada stocking either system? I have a bunch of AR mags already, but something that takes AICS mags would be totally fine too... I've heard that you need to permanently modify the AR mags for it to work anyways... How difficult is a bottom metal system to install? Anyone with some experience with either?
