Adam Heggenstaller has just posted the first concrete detail of the consumer Bushmaster / Remington / Magpul ACR …
The cool thing here–other than it being a brand-spanking new gun that you can get your hands on real soon–is the ACR’s modularity. The consumer version will be offered with a 16.5-inch barrel, but Bushmaster will also be making barrels with lengths of 10.5, 14.5 and 18 inches. The first version of the ACR will be chambered in 5.56×45 mm, of course, but since a tool-less disassembly allows you to change bolt heads, barrels and magazines, the ACR can be user-configured to run with other cartridges as well. Ongoing development will focus on the 6.8 mm Rem. SPC, 7.62×39 mm, a yet-to-be-disclosed 6.5 mm round and, get this, the .30 Rem. AR.
