Just seen several videos on guys buying kits and manufacturing there own ar 15 lowers out of polymer. i have some of the omni polymer lowers i have no complaints i have 20 or more in forged aluminum which is by far the better way to go.so i was wondering is it legal to do this in canada? if so has anyone on here done it and what was the quality of the lower. i know there are lots of people that hate polymer lowers but i have nothing bad to say about the ones i have. any feed back is welcomed thanks

That is regarding import. You can, and we have made and registered both Ar10 and Ar15 lowers from scratch (I was shooting one of mine the other day). If you follow the proper procedure it's actually quite simple. Most people just don't have the skill or equipment to do a scratch build ( from a block of aluminum as opposed to assembling a group of parts)
 
I wouldn't want to be the trial Canadian court case triggered when I tried to registered it.

The kit is probably ITAR controlled, good luck lawfully *exporting* it from the US.
CBSA might also give you grief if you tried to lawfully import the kit.

Given that it has to be registered in Canada in any case, I don't see much value in making your own AR15 lower versus shopping carefully in Canada.

In the US the attraction is that in many states you can lawfully make your own AR15 lower and populate it without
having to notify any federal, state or municipal authorities.

Curiosity: what do you do for anodizing or other coating? DIY?

Three paragraphs of opinion without knowledge. Fourth paragraph can be agreed upon.

We sent them out for anodising. One thing to note is that when we did them we were slow at work, and at that time Lowers were difficult to come by and expensive. We did the first home made AR10 lowers in Canada at that time and had to wait a couple of weeks and submit pictures so they could approve it and generate an frt. Hard anodising is charged by weight with a minimum charge. Back then the minimum was $130. One lower cost $130 and six lowers cost $130. The most difficult part of doing a lower from scratch is the magwell. Mass production lowers are broached which takes all of 30 seconds, we edm'ed ours at about 3 hours for an ar15 and double that for an ar 10. You won't get an endmill small enough or long enough to give you the sharp corners for the magazine, which means you finish it off with a file. You can get a fully finished stripped lower for a hundred bucks or less, Making your own even an 80% just isn't worth it, especially if you also have to buy the drill jig for the 80%.
 
Again, nothing illegal about making your own as long as you register it. We've actually done it along with a number of other people with zero issues but like you said, for $100 or less it's not worth the trouble
