    First range report on the ZRTS +5 APC9 mag extension.

    Ran approximately 200+ rounds through it yesterday. Round nosed, flat nosed, 115, 124 and 147 gr as well as some aluminum cased ammo. Had zero issues loading the mags and zero issues during live fire.

    I feel good enough about it to run it in a USPSA match next weekend!

    The little added weight helped to drop the empty mags while the bolt was open.

    If you are looking for a metal extension, these are the best on the market!

    Shipping couldn’t be faster. I bought them for competition and so far haven’t used them there, but in my testing they work great with no modification to the mag’ required. Installation is a breeze and they are very well made. When I contacted ZR Tactical my inquiries were handled rapidly and the questions were answered fully. These mag’ extensions were suggested to me by B&T USA. Also a pat on the back to B&T USA, great folks and fantastic customer service.

    Very high quality part. I tested at the range with zero issues. ZRTS gives me every impression they are a quality outfit. I’ve ordered B&T guns and accessories from them and all has gone smoothly.
