A lightweight Bushmaster,..the QRC.
It's just bare bones and comes in at just a hint under 6 lbs. I haven't got any optics on it yet so I haven't shot it, but I'm impressed with it's fit and finish considering that it's a base model. There's no grittyness in the bolt and the trigger was a nice surprise. It's not particularly light, but it breaks very clean.
The collapesable buttstock is a bit loose, but I never much liked them anyway. One of the very few changes I intend to do to it is put an Ace skeletal buttstock on it,..which will drop a few ounces of weight and provide a more rigid shoulder point. The Ace also comes with an optional 1" butt pad which should make the LOP more proper for my long arms.
Like I said,..it's just a toy. Except for the stock and a scope I'm going to leave it just like it is,..no geegaws. I want to see how well one of these ultralight AR-15 carbines can shoot.
