The g2 is a small frame AR 10 for lack of a better term. A hybrid. It's a 7.5 lb 7.62/260 that had the larger mag well, a bastard sized lower, upper, bolt, bolt carrier. The bolt was a double ejector design which certainly worked well. The barrel nut and extension were proprietary as well. When Remington went belly up DPMS folded and a lot of folks got left in the lurch. Parts of course got scarce. Now several other companies are working on a small frame And some use some of the G2 design. Zev, POF, The MA 10, Adams Arms, are just a few. I think Ruger and Savage are trying their hand now as well.
The G2 was a very good platform with some solid improvements over the LR 308. Especially for the hunter where weight was concerned. Parts are popping up from these other companies now that cross with the G2 platform but it's a bit of a job to learn exactly what does cross. Since Adams Arms sells a complete piston kit for the G2, I figured the bolt might cross so I emailed them and got a good answer.
Parts haven't been easy to find with Remington going under so it's nice to see this happenin. It's easily my favorite gas gun and has been ultra reliable. Mine started as their Hunter model with a carbon fiber hand guard but has been modded into more of a SASS configuration. You can google DPMS and still look at all the DPMS models.
One of the Issues with the DPMS G2 was the aperture or firing pin hole was too large and tolerance on the other end at the tip of the firing pin was small. Many pierced or cratered primers badly. Before I could get a replacement the company folded. I could have gotten the bolt bushed and still may as a backup. But I wanted to try the Adams bolt first.
