A little look at what we’ve been building. 🌊

From the VPRS lineup to our trigger spring sets, every product carries the same Neptune Defense commitment: Strength Beneath the Surface.

Which one is in your setup? 👇

Huge thank you to everyone who stopped by our booth at Spike’s Tactical 25th Anniversary event!

It was great getting to meet so many of you, talk shop, answer questions, and put some faces to the names that support Neptune Defense.

We appreciate every conversation, every handshake, and everyone who took the time to come check us out. We had an awesome time and hope to see you all again soon.

And a huge congratulations to Spike’s Tactical on 25 years! 🔱

Just a snippit of our upcoming long-form videos explaining the science behind how a VPRS-15 reduces 30% of felt recoil, and improving harmonics of the entire system.

Dial in your rifle's recoil impulse and keep your sights glued on target with the Neptune Defense AR-15 buffer and spring setup. Whether you're running suppressed, chasing a softer duty cycle, or trying to eliminate bolt bounce during rapid strings, upgrading your reciprocating mass completely changes how flat your carbine tracks. by @neptunedefense

The Ranger 9X from Miller Precision is a great example of what happens when every component is engineered to work together.

We had the opportunity to work closely with the Miller Precision team to develop a recoil spring that matched the platform. Through extensive testing, we landed on a variable pitch and variable diameter spring design to deliver the reliability and cycling characteristics the pistol demanded.

The Ranger 9X also packs some seriously thoughtful engineering:
• Linkless barrel system
• Fully ambidextrous slide release
• Quick-change compensator system

It’s always rewarding to work with companies that are willing to rethink the details instead of settling for “good enough.”

Check out Miller Precision and let us know what you think of the Ranger 9X. by @neptunedefense
