Oly Arms 16" A2 kit. Even without the lower receiver, it makes my Mini-14 look like a piece of crap. Now, where the hell am I going to get a lower receiver? For those of you that have played with the 80% lowers, just how hard was it to finish? I'd like to say I have moderate to advanced skills when it comes to mechanics, but is this over my head? If it is just simple drilling, I have a press. What do you think? Thanks guys.
