That is a smoking deal!
Mine was $300.......
80% lowers are not really a "deal" here in Kanuckistan. In the US, you build it and there's no papers. Here it still needs to be registered.
There are a couple of places in the US that will ship to Canada, but make sure you use their jig, every manufacturer has different things they do to get to 80%, so jig from company A May not get you to 100% with company Bs 80% receiver.....
When I did mine, I did it for the satisfaction of doing so. I spent $100 on the lower and $300 on the jig. Shipping et-al was $459, plus GST at the post office on pick up.
All in I spent about 4hrs with the drill press and a milling base. Registration took a tad over 10 months with several emails to the CFC techs etc. I had to send copies of the plans and pictures with measurements of the lower to the techs....... They wouldn't let me register it as a lower. I had to complete a rifle to register it. Just FYI.
I purchased mine about a month before aero-precision lowers became available up here for $129.......
I was thinking about a 80% upper next, but to be completely honest..... I don't think I'll bother....
I have no plans to rent, loan or sell the jig. I may pick up a couple more 80% lowers in the future. Now that I have the jig etc.......
