Dwight Williams of Williams Arms Company, in Sisters, Oregon, introduced the Aluminum Combat Elite around 08-01 (?). Beautifully machined, it endured one man's 1000 round torture test - then cracked. Tested with proofloads by White Labratories for DSA (http://www.dsarms.com) it failed catestrophically. I have examined the splintered shards of the receiver. Several other people have had locking shoulders and ejector block pins walk out. I have examined photographs of several other full and semiautomatic aluminum receivers with cracks. Although possibly okay for pistol calibers, I choose not to complete this review with a live fire. I have serious reservations about its safety and structural integrity.

Dwight Williams unethical behavior with regard to customer concerns over the safety of a WAC receiver has further reinforced my decision not to work with this product.
