I've had two Dlask lowers, three uppers, and a complete Dlask built mini moose.
My current AR build is mostly Dlask, and it is the best one I've done so far of about three dozen.
The only issues I can personally speak to were with the older Mini moose ...
way back when, Dlask used powder coating instead of anodising, and this made some pin holes tight.
PS: I like the made in Canada factor.
