I was going to build 18" guns, until I saw the videos below. The increase in velocity using an 18" or 20" barrel over a 16" barrel is insignificant. I chose to use 16" barrels. I plan to build a 6.5 Creedmoor on an AR-10 platform. I'll use a longer barrel on that gun.Liberty wrote: ↑Wed Sep 12, 2018 11:32 am I am looking primarily at Anderson. I wish to build with an 18 to 20 inch barrel. Probably never put a scope on it, although a red dot might be installed. I want mostly reliable, more than pretty. Likely use Magpul MOE furniture.
What confuses me is differences between a 40 dollar Anderson, and a $300 dollar stepped lower. This will be a project gun, and I expect that it will take me a while to purchase and build the whole gun.
