Impressive combo set. SI-Defense is really trying to make a name for themselves.

Ok... maybe just one more receiver set build...

I've actually been waiting for this.

I did also say that if something gets built up, something else will be torn down for parts. I already have a list of sacrificial lambs...

As a lefty, I'm really more interested in the features vs just building something new for the sake of it. In this day and age, I'm surprised how few, true ambi receiver sets there are.

Boy, that would be ideal. I was eyeing 16" BCM uppers this evening

Wow that's a good looking set! First time I had found out about SI-D was the 308 set UW posted on FB. I'm a righty so often ambi safeties annoy me but the bolt and mag release would be nice. Just under 500$ seems about the norm these days for high end billet sets like these.

Could not agree with you more. The Mega ambi's with a Norgon mag release is just as good as all the so called new designs. This is certainly a fresh approach.
