TFBTV did an overview of the Crusader Templar.
1. upper/lower not compatible with standard AR uppers/lowers.
2. AR triggers and other small parts ARE compatible.
3. mid length gas.
4. 6061 billet aluminum.
Personally, for $1,800, I'd rather save up a little and get a CZ Bren instead. This would be nice as a collectors item though.
The "Clever Legal Workaround" mentioned in the video description, explains a lot about their law.
"We moved the front and rear pins about a millimeter and made it non-interchangeable with any AR upper or lower, and that makes it legal."
The XCR is not interchangeable, but existed at the time the law was written, and they named everything that was not AR that existed at the time the law was written.
So, their game is to change the dimensions slightly, then wait for the next round of laws and new names to be added to the list.
The group of new Canadian products looks to be squarely in the middle, between the ARs and the SCAR/ACR/XCR/etc. group. If it weren't for the legality situation, they might not be viable at the price point they are at. I'm not saying they are overpriced. The labor cost may justify every penny. But if those others were available, the "For a couple hundred dollars more, I could get a fill_in_the_blank
" argument would really cut the market down.
