MAT-9 Upper Fitment Issues
I sent an email to info@ last week, but thought this couldn't hurt.
For reference, the lower I'm using is an Olympic SGW that I've had for a couple decades and has seen many uppers. I also tried to mate this upper to two Stag and a Spikes lower w/o success.
The first item is the width of the front takedown lug. As you can see in the picture, it measures ~.5055. I can just barely get it to fit into the SGW lower, but no other I own.
The second item(s) is the two takedown holes. They're more like slots. The two pictures are of either hole w/ a .2500 gage pin inserted.
The third issue is the distance between the two takedown holes. Once pinned to the front lug, the rear hole doesn't align w/ the lower (it appears "short"). Pic depicting.
And the final issue is the gap between the receivers' mating face(s). Neither their decks nor the extension lug area are close. Pic depicting.
I'm hoping this is easily resolved and I understand if you need to put hands on it.
Thanks.
