Worked as advertised with no problems.
I would recommend this product to anyone wanting to make a 9 mm conversion.
This Adapter Drop In Mag Block converts your standard AR-15 model to accept affordable, lower-penetrating 9 mm rounds using a COLT STYLE MAGAZINE. Made from 6000 series billet aluminum with a steel insert for the feed ramp.
NOTE: Use 124 Grain Ammunition
