    .308 ARs may not have a lot of parts commonality or standardization, but the GII platform is a new, and welcome, oasis of potential; a rifle that multiple manufacturers can contribute interchangeable and compatible parts & accessories to.

      How interchangeable are mags?

      • ostiariusalpha

        The industry has pretty much solidified around the SR-25/LR-308 magazine as the standard, the GII is no exception to this. That being said, this platform has issues with Magpul’s gen3 mags not lifting the bolt catch high enough to completely latch onto the bolt group, causing damage to the top of the bolt catch or even failures to lock back. The GII is not the only rifle to have issues with the gen3 mags, but it something to be aware of. Often, a simple modification to the top of the mag’s follower with a dremel will correct the problem; there are threads on several forums that cover how to do it correctly.

    Who’s selling G2 pattern lowers?

    • ostiariusalpha

      Unless you’re buying them off Gunbroker, nobody. DPMS will indeed sell separate lowers eventually, because parts sales is the real core business of DPMS. Still, this deal is mostly aimed at people that already have a GII or SF-308 rifle & want an alternate upper for a different application.
