I couldn't agree more on outrageous "unobtainium" mark ups, but prove to me there is a source in Canada to buy Colt 9mm AR15 5/32 pinned hi-cap mags for $85 - I've been searching for over a year without success and only $300 per mag offers on CGN.
The only known sources are ATRS selling converted Uzi mags, $115 each and Questar selling 10 round stubbies.
Gossip, ie: "I paid, blah, blah," is pointless - we're all looking for a dealer that has stock, not a once upon a time story.
DeadZombies hasn't quoted a price yet, but $85 sounds likely/reasonable - if US retail is $50, as Rebel Rouser said in earlier posts, hopefully it'll be lower but I'm not going to suggest it without information to support it.
Irunguns deals with Colt also, so they're another source, nothing in their inventory right now, but would likely cost more with their individual item shipping fees/border processing.
Anyhoo, tell DeadZombies/Dlask you want them - or else the boss may decide one small order isn't worth it and we can back to complaining about lack of availability, all the best.
