Welcome to Best Quality Lowers. 

We have over 20 years experience machining high tolerance parts for personal, professional and military use. We manufacture 80% lowers for AR-15 in .223 (5.56) and LR-308 in .308 (7.62). Our respect for the home AR builder, our professional experience and our attention to quality and detail ensure that you get a custom, high end product. Our parts are both in DPMS platform, with the AR-15 80% lower conforming to MILSPEC standards. (NOTE: The .308 lower is NOT an AR-10 platform.)

Thank you for visiting.
