I had an extra lower sitting in the safe that couldn't sit alone by itself any longer. I've wanted a real light weight carbine for a while now and have really wanted a dedicated carbine with just iron sights to shoot with. I have to say I think it turned out well, the 15" handgaurd lends to a really nice long sight radius and just mounting the sights it was pretty much dead on at 50yrds. Now maybe it will stop raining long enough to put some more rounds down range with it
