    Ambi mag catch

    Posted by Brant on 27th May 2023

    Great little device, tucks in under a Geissele Maritime bolt catch too! No problems with using either. You have to take out the G bolt catch to install but that’s an easy tap out. I’m very happy!

    Ambidextrous Magazine Release

    Item works well for left handed shooter. Left side is small and but easy to decern from bolt catch. Releases empty mag with minimal effort. Full mag requires more pressure.

    High Value Ambi Mag Release

    Posted by Jimbo on 30th Apr 2023

    These AU ambi mag releases seem every bit as good as the original Norgon. No modification was required for my LMT and Anderson lowers.

    This is THE one to buy. It stays out of the way so you can work your bolt catch. If your a lefty this is a must have! I

    I would have paid a lot more!

    Posted by Brett on 21st Apr 2023

    The quality of these are unrivaled by any of the competitors! I have a few different brands of Ambi mag catch/ releases. These by far are some of the best and at a price u can’t beat! I literally put one in every AR platform I have. It’s a great product sold by a great company. Keep up the good work!

    Overall pretty good

    Posted by Jacob Ford on 14th Apr 2023

    I ordered 2 of these. I would have given five stars except the spring in one would not allow the ambi side to depress enough to function. removing 1/4 of a coil from the spring solved this. the second one functions flawlessly. the placement and operation is great. they are unobtrusive but right where you need them, and they do not lever off of the receiver causing wear. overall a great design, and AUs pricing is very reasonable.

    Wow, way to go Arms Unlimited! The part arrived early than expected, installed in seconds and works perfectly. No fitting, just installing. I can finally Chang mags like a normal person. I will definitely order again.
