I only quote you to tell you that you're a complete ass and don't know what you're talking about. DPMS basically made the GII an open source platform. They were instrumental in "normalizing" the AR10 (think SR25 pattern). They bet big on the GII and won. I will not only tell you what I know but I will tell you why I know it. Walked in to LGS and I see a Diamondback Firearms AR10 sitting on the shelf, 16" barrel. I have been shopping for an AR10 and had no idea what a "small frame" gun was at the time. I look at the gun and the owner brings out a Diamonback AR10 (SR25 pattern) pistol with a brace on it, readily available on Diamondback's website. We start chatting and he lets me take it out back to the range and shoot a couple of rounds. Gun is very smooth for what it is (a 13" AR10 SR25 pattern with a blade brace) so I jump at the one on the shelf and drop a K. Start ordering parts for it (phase 5 bolt release, trigger, muzzle device, etc). Bolt release comes in and it wont work, bolt carrier wont even travel more than a half inch. Multiple conversations with Diamondback, Phase 5, 2 DPMS dealers, and a couple of gunsmiths and heres what I found out... I had purchased part number DB308G2B, which was a PART FOR PART copy of the DPMS GII... yes, you read that right, PART FOR PART. DPMS made the GII platform open source, so any one could make it. It was like pulling teeth getting info from these people. Adams Arms manufactures under license because they used part of the design and added a piston upper to the GII lower. Also found out that POF's stuff is mostly proprietary, especially the BCG. Look at their website for more info. Not only did Diamondback make a PART FOR PART copy, Remington got involved with the platform and the R10 will have more than 90% compatibility. They changed the barrel nut a bit to improve accuracy. The different parts have not been cross installed and tested as far as I know. Diamondback made a good run of a few hundred guns, but has since stopped production AND support for the gun. Im guessing the recent shake up with the Remington and DPMS family of companies has something to do with it. Same reason for the web pages being down. Now, if you would stop being an ass long enough to do a little interwebs looking you would know that Sig had a pre production gun at Shot Show range day. Springfield already has one going, and is shipping new models of it Q2. Remington makes one and I hear its damn nice. Adams Arms is churning them out as fast as possible. Diamondback, ZEV, and F4 defense made probably more than 6000 copies between them from what I can tell, but all dropped out due to lack of marketing, and thats exactly what caused the OEM's that made them go under. Diamondback presented ZERO info on the platform in ANY of their online presence... just kind of expected people to know what it was somehow. ZEV and F4 produced over the top expensive stuff, and nobody knew what it was. Aero Precision and PSA are rumored to be getting into the game. The only reason DPMS isn't making them right now is because of corporate restructuring, but there are still plenty for sale. The new players at the table are the big ones, and they are sticking around for a reason. The platform kicks a whole bunch of ass. My Diamondback DB308G2B punched 1.2 MOA out of the box with match ammo. Now add a trigger and a muzzle device (currently shopping for a barrel) and I have printed targets as small as .8 MOA. This was all done in an indoor range at 100 yards. It kicked out of the box like a pissed off mule, but some goodies tamed that a bit. Still stronger than an AR15 but not as bad. Lower weight, better accuracy, better ballistics, smaller package, more modular, and easier to handle 308... that's why it was a big deal. The whole idea was taking the FCU and buffer system from and AR15 and making most everything else .308. Doing that actually presented some form of a rough standard, because the FCU was already standardized in the AR15. The open sourcing allowed different OEMS to buy castings/forgings from the same peeps making them for DPMS. Now that I have educated you on the subject matter, go verify it for yourself if its that important to you. I spent so much time here typing to help a fellow enthusiast that asked the original question, not to scold you (that was just a bonus). That is what you're supposed to do in a community such as this. I will never understand why people feel the need to be whiny little bitches and poke a hole in something instead of helping. I think you belong on Reddit or 4chan.
