Retail is close to $500. The Sub2k is fun - but if you want to use Glock mags, build the AR.
For $675 I'm going all out on building an AR that takes Glock mags, could get it to basically the same $500 by going with a cheaper standard upper. I really like the left side charging upper with last shot hold open that works for Glock mags is the major extra cost, but I *really* prefer that style vs. traditional AR rear of receiver.
Could go for a slick side upper for $80 vs. the $230ish the side charger w/ lrbho ... and I still might.

Barrel is tricky.. $75 to $150, I might be able to do local pickup from Daytona Tactical ($75) but I've heard about shipping issues with them... and some forum spamming. Probably go NFA "cheap" at $110.
