Re: entry level ar
When you say middle of the road, how much do you want to spend?
It's all going to be based on your budget.
You can get complete AR15s for $500 from Radical Arms, which has some QC issues and some owners having no issues.
For around $600 I'd recommend getting MP Sport II. I'm not a fan of Armalite for their business practices, but they also offer a $600 AR15.
If you have some mechanical aptitude, you could build an AR15 with minimum tools.
