How about just a shout out and a thank you to everyone who made these possible. Y'all are great.
Then the shout out should go to Alberta Tactical Rifle as it was they who broke the ground for the black style NR semi autos.
JR and Sterling simply ripped of the design from ATRS and are now profiting from it. Yet again JR's true colors come through.
Hardly accurate.. the thanks from us should go to Jeff from NEA who broke the ground a couple of years before ATRS on the NR Canadian made black rifles.
Lots of people on this forum love to hack on NEA and while they had a lot of QC issues, they pioneered and invented a lot of things.... the minibrake, the CSS stock and the NEA102 was out way before the ATRS system.
I also approached ATRS (which they confirmed) prior to going live with my project....
I also have nothing but respect for ATRS and Rick's contributions and abilities, he makes a damn fine product.
Condemn me if you will, but get your facts straight first.

I Might be wrong (I checked and im not) but im pretty certain the ATRS modern hunter and varminter predated the NEA102... They were expensive but paved the way for sure.
Any of these receiver sets left? I was teliing a buddy who isn't a member here about them, and he's interested. ATRS is too rich for him, but these are in his price range!
I've seen the pictures earlier in the thread, the question is: has anyone function tested a SAI upper with the other Albertan lower?

A guy I know tested this, he said the the sterling upper fit nicely on an ATRS lower but a sterling lower on an ATRS upper didn't quite fit because the front takedown pin was just a hair off but a tiny bit of filing/sanding would have resolved the issue
Here is a couple of pictures of swapped SAI/ATRS uppers.

Can we use our own rear take down pin with your set, unlike the ATRS which requires drilling?
I am unsure what you are asking?
There is a supplied rear takedown pin with each system. Once the front pivot pin is pulled out, the upper simply slides forward and then lifts out. In actuality, the rear takedown screw never needs to be removed.

Sorry I was confused because in the above pic there was no rear pin installed so what I really want to know is, how does it stay in when it's installed?
Not sure of asked before but anyone have luck with gen 3 pmags? Mine won't go far enough in cause of the over travel spine. My buddy tested gen 3 pmags in his alberta tactical and they fit fine, my earlier gen pmags and usgi mags fit fine though.
A removable rear takedown pin is useless with these anyways as they were never designed to pivot open. The bcg sticks out the rear of the upper and the lower is squared at the top around the front pin.
