      Extended mag

      Posted by Ryan S on Oct 7th 2023

      It’s made out of really nice material. Feels great and looks great. I was actually able to get 8 extra rounds in mine, which is awesome. Shipping took forever but other than that. Wish I would have ordered an extra one.

      Man, I knew that Excess Arms was solid but I had no idea how solid the PSA mag extenders was until it was in my hand. No doubt this adds value to my collection. Thank you

      I am missing one of the set screws. Other than that, everything works well.

      Best magazine extension I have ever seen.

      Posted by Alex on May 13th 2023

      First off, the finish on these is really nice. Everything regarding the machining and finish is on par with high end gun manufacturers. The ease of installment! This thing absolutely without a doubt the easiest magazine extension I have ever installed. It cycles well, it functions well. It does what you would want a magazine extension to do. I will definitely recommend them in the future, they function well, they're easy to install. They're definitely worth their price, and if another company makes a more affordable one it's going to be hard to compete with the durability of this one. I think this will be the go to magazine extension for the 5.7 Rock for the foreseeable future.

      PSA 5.7 mag ext

      Posted by Nick on May 5th 2023

      I’ve been all over the internet looking for an extension for the PSA rock. This was my third purchase and should’ve been my first. The other two prior to this were junk, fell apart when I shot etc. I shot the sh*t out of this one with zero issues. Its machined excellent and the retention screws to circumvent the bottom plate , are genius. Feels nice and you can just tell it’s a good product. Great product guys keep it up !

      The extension is high quality and the finish is immaculate. Had zero issues installing it on a magazine, and loading it is easy peasy. Shipping was fast and customer service from the company is absolutely top notch. 10/10 Will definitely be a repeat customer.
