An LEO and reader of ours recently passed along a report of a blown up weapon that was in use within his department. The report, which was made after an analysis by Small Arms Solutions, details an AR-15 with a Colt lower and an LWRC 10.5 inch upper, which seemingly experienced catastrophic failure due to a faulty Federal Ammunition American Eagle cartridge. The full details of the report can be read in the attached .pdf. Additionally, all three companies, Federal, Colt, and LWRC, are working with the department to correct the issue.
