Sub 5# build

I built this a while back just to see how light I could build it without going broke.  I mainly used the AR parts/weight database but also read up on other lightweight builds on the web.  Two things I did a little different, one was I did not use an aluminum bolt. Second, you can spend $100 on a lightweight handguard or $300 on a little lighter handguard.  So I didn't buy the lightest/most expensive parts.  I think I'm right about $1k maybe a little under. No plastic.

Mag Tactical lower, slick Spikes upper. Guntec honeycomb furniture set but the stock/tube they use has a big slug of steel on the end so I went with an Anderson carbine buffer tube. Rock river arms 2 stage trigger, faxon pencil barrel and slim 3 port brake. Brownells lightweight steel bcg. Strike Industries charging handle.

You can shoot it one handed. :)
