So I mentioned earlier that I have 3 AR's that I built and I do. Though I say built it's really I just ordered all the parts and assembled, but still I did all the manual labor!
My first AR the first actual gun I've ever owned and on top of that I assembled it myself!
The box is from PSA, i bought one of their diy parts kits for the first build.
What it looks like now, yes I had to put a bump fire stock on it, it's a bump fire systems.
The other two only have one picture of them both, but still AR goodness!
Two rifles are built off of Anderson Mfg lowers, and the third is built off of a Tegra Arms Carbon Fiber Lower I got on sale for $35 and free shipping. All rifles are in 5.56x45mm NATO.
