in my experience it wasn't the magwell but rather the magazine that made it necessary to modify the receiver. the magwell fits fine, but when you insert the mag it passes through the magwell ok and then hits the tabs in the receiver. no magwell would change that. i presume some magazines are narrow enough at the top to fit and some are not. my experience is with metal cpd lar mags.
the other issue is with the new bolt catch. in my case the bit that engages the follower and holds the bolt open after last round was a bit too long and hit the cases when a loaded magazine was inserted. again, this may be magazine-dependent.
Just got a Tommy Built one, and really like it far more than what I have seen of the Spuhr unit.
Takes PMags with not additional messing around.

where did you get a tommy built magwell? And what was the cost to get it here?
