AR-15 Glock Conversion Block March 10, 2023 : Patrick Miller from Valley Center, KS United States   Junk. It scored my magazine well because it was too tight. The mag release cracked and the spring fell out. Don't waste your money. ------------------------------------------------------------------------------------------------------------------------------------------------ MAS Defense Reply: Patrick, I apologize for the issue. We have sold thousands of these Sylvan Conversion Blocks with 99% customer satisfaction. The block should have dropped in or at the most required very little pressure to slide into the magwell.  Forcing it in to the point it cracked under pressure or left marks should not happen. Customer service will reach out to discuss further. Thank you for your business and your feedback! Was this review helpful to you?
