$200 at Blackrose Tactical gets you an Atlasworxs DBM. Made in Austrailia and styled after the Badger DBM but almost $400 cheaper. Machining is nice with no chatter marks but edges are more square. Not as refined as the Badger and doesn't include the bedding pillars you get with the Badger either. You can order direct from Atlasworxs, $165 USD shipped from Australia. I don't know if there will be duties and brokerage on top. Blackrose doesn't advertise the DBM's as Atlasworxs but thats what they are. I have one waiting to be installed, inletting is required and I believe they use a Badger M5 inlet. Another affordable option is PTG at $130 USD plus shipping. Jerry at Mystic Precision sells CDI, last time I looked they were $245 CDN. All are anodized aluminum copies or spin offs of Badger. And if you do a search, Barney AKA Tactical Teacher did a writeup on fitting the Magpul DBM to a cheap R700 tupperware stock pretty easily. $110 at CTCSupplies.ca. All use AI mags, I'm a fan of Accurate Mags. They allow a max OAL of 3.055" and insert on a closed bolt. I wasn't overly impressed with MDT mags but at $40 a pop they are cheap.
