Precision well made product - Stern Defense MAG-AD9 AR-15 Glock 9mm/.40 Magazine Conversion Adapter

This is a well-made product with evidence of pride of workmanship. The edges are straight and precise, the magazines fit snugly, the mag release work perfectly. This is the second of these I've ordered for Stern Defense, that's good evidence of my opinion that this is a well-made product.
