Accurate-Mag 5-shot Magazine .223

This is a quality magazine. I used for 300 Blackout and had some issues but that may be due to me using the magazine for an unintended purpose. There is a lip on the front of the magazine the tip of the bullets were getting caught under. I solved this by getting out the dremel tool and notching out a small portion. After the modification, it worked perfect. Keep in mind it may work flawlessly with 223 as I has cycling issues with 300 Blackout.

Advantages: Solid construction.

Disadvantages: Possible issue in the design causing feeding issues (but can be fixed if your handy).
