Liv2hunt Posted September 12, 2013 Report Share Posted September 12, 2013 I'm wanting to build my first 308 and am fairly new to the idea of a 308 on an AR platform. I want the gun to be as light as possible and was wondering if anyone made an AR type upper and lower receiver out of carbon composite materials? I like the Bushmaster version, but I think they only make theirs in the .223...any ideas? Quote Link to comment Share on other sites More sharing options...
EasyEJL Posted September 12, 2013 Report Share Posted September 12, 2013 I haven't seen carbon fiber, but did see magnesium somewhere. Hmm no, now that I look that was 223 only also. Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted September 12, 2013 Report Share Posted September 12, 2013 MAG tactical says they are planning a 7.62 version of their lightweight magnesium lower receivers. They were planning on releasing a magnesium upper receiver, to match their 5.56 lower, later this year. They say, after they finish the 5.56 line, they'll get started on the 7.62. I recently bought a MAG 5.56 lower for my wife. I know a few guys have them here. They are super light! I'm planning on a sub-5 lbs .22lr for the wife. I hope to have it finished around Christmas time. Quote Link to comment Share on other sites More sharing options...
shibiwan Posted September 12, 2013 Report Share Posted September 12, 2013 You could go 300 BLK on the Bushmaster Carbon 15.... -S Quote Link to comment Share on other sites More sharing options...
