Aero EPC Mag catch upgrade


21 in stock


A replacement magazine catch for the EPC lower that raises the installed height of magazines to help with inherent feed issues.

Best results are obtained when used with Macon Armory Builders kit Or a Macon Armory Barrel and Buffer coupled with an AERO bolt.

Faxon Bolts and similar clones have issues and Macon Armory advises strongly against their use with our products.

As always….Macon Armory Deadblow buffers are intended to be used with a standard 5.56 AR carbine recoil spring.

    This single handedly solved all of my failure to feed issues. I built an AR-9 using the EPC-9 upper and lower receivers. I had all the parts that are well regarded as optimal for an AR-9 build, but the gun still would not feed hollow points. Even with the Macon Armory Guaranteed to Feed barrel.

    A fellow Redditor pointed me to this mag catch, so I gave it a try and I have had 0 malfunctions with Federal HSTs and Sig Sauer Elite V- Crowns, two of the most jam-prone bullets in the AR-9 platform.

    If you’re experiencing feed issues with your EPC-9, get this. It takes less than 5 minutes to install, it’s affordable, and it works.

    hey, I am the first to leave a review, yeah, all joking aside Rudy you are the man! I love your mag catch for the EPC-9 lower! it not only raises the mag up so the bullet is lined up with the bore better but it also eliminated all the slop I had with the mag being able to be pushed up or down with the factory Aero catch. thank you so much for all your help on all the forums too! I will try and post some pics if that’s ok and if it works.

    This was the final piece I needed to resolve the feeding issues I have had with my EPC. Now my EPC easily eats all the flat-nosed and JHP rounds that it used to choke on. Thanks, Rudy!
