I hope PA continues to stock this product. Game changer.

Excellent Upgrade!


PA is one of the only places to stock this product. It is a fantastic upgrade to milspec rifles and an essential one for competitive shooters looking to cut down on reload times.

Worthy Upgrade

The HRF CRCM is a plus for those looking into faster reloads. However this item is not compatible with the ATI Schmeisser AR-15 5.56 /.223 60-Round Magazine.

I tried to install it on 4 different rifles and it didn't work on any of them. They were loose and didn't fit. I lost my money.
