    Speechless

    Posted by Tai on 21st Jul 2024

    I’ve been looking for the final thing for my MP5K clone build. There are no words for this… It was one of those gamble purchases and damn did it payoff! Performance is stellar, for some reason the trigger pull feels better than a normal franklin. I’ve used binary triggers before and I am confident with them. They take a little practice but I can get mine moving around 750 rpm. This thing looks amazing. I mean really amazing. I’m a little curious why it’s not sold with a trigger guard (I imagine so you can pick your own) I just used a magpul I had layjng around. Finally, but certainly not last… the feel of it is insanely good. I was going to use this magpul vertical grip and then thought, why wouldn’t I use the one I use on all my ARs and holy shit! It’s like finding the perfect steering wheel for a long time garage build. I’m happy to say that my once so-so PTR-9K is now a badass MP5K clone! It is officially stamped, test fired and every single part is exactly what I wanted… no cut corners. I wish I could post a pic up. If you have any doubts, don’t this is one well made piece of gear.

    Wow

    This thing is breathtaking! It was one of those “damn, I probably shouldn’t have bought that.” Right up until it showed up. One you see this in person nothing else comes close to looking this good. The trigger feels fantastic and now I realize why Franklin Armory has a pricey install fee because I have another PTR that I installed the binary trigger in and this one is so much nicer. I changed the grip to another Magpul grip and just like that, my PTR9K feels amazing. Great purchase!
