Works as intended

Chose this as a less expensive option to a plan B mount. Works great!

I tried for two weeks to get one of these, even tried Sig Sauer and all sent the wrong part. Ordered from Midwest got the right part in days. Thank you!

Ordered this to support installing AAC muzzle break for SDN6. Worked like a charm. Now surpressed with MI handgaurd. Such a sweet set up.
