Click on the picture and it'll take you to the page for it. More importantly when are you going to start making lowers as well???

At this point I can very well imagine you guys selling complete assembled uppers now,
Looking forward to see what comes out of this
 
The Stag-10 seems to always show up as either a receiver set or a complete rifle, so I'm not sure there are a lot of lonely lowers looking for one of these uppers. Or is the business model that someone can do an alternate upper, eg one with a target barrel and scope while the other is a pencil barrel and red dot?

For me I would like to have a second upper, just to have the option of going 6.5Creedmor or 308. It might be more a niche market thing, but I would hazard a guess that most Stag10 owners would be interested in a second complete upper.
 
Does this upper also include Forward assist? It is showed in the picture but not in the description which says dust cover included.

I have 2 uppers for 1 lower and want 2 more. Cheaper to build a new upper vs building a whole rifle. Almost build 2 uppers for the price of a complete rifle

If this fits both Stag 10 and Matrix M762D, does it mean a Stag 10 upper fits on a matrix 762d lower?

That’s what I was wondering, but I just found out IRG’s post on the Matrix says the Stag and Matrix actually have interchangeable receiver sets.

Does anyone have a Stag or Matrix upper to weigh? See what the weight savings might be on this upper compared to the factory uppers.

Yes this is the idea. Someone now has the option for a completely different upper setup. Seems there are alot of people wanting these because the first production run is nearly sold out now.
