    Hi guys, I am looking to change the upper receiver on my Bushmaster AR-15. It is now an A2 upper and I wish to change it to an A3 flat top configuration. Are the A3 receivers sold by Bushmaster what I should use? If not what company makes quality A3 receivers? I would like to hear your thoughts before I start this rebuild? Thanks

    Check out Brownells and DPMS, some of the mfg's.

    I'm on the same quest as Stephen. I have a Bushmaster lower and want to swap out my upper to an A3. There are a lot of brands and a wide variety of prices on the market. I don't need "high end" and I don't want "crap". Any recommendations for a solid upper without the fancy price tag?
