Best integrally suppressed 300 BLK upper points to consider
W have been building some the best integrally suppressed 300 blk upper designs for over 10 years at this point. The first time we debuted our original Leonidas integral at the Silencer Shoot in Dallas TX, it was received with much praise and loved by everyone. This is a photo from that day, just look at all those vintage widgets on that thing!
We did a bunch of special things in that design that were never really done before with an AR15 upper integral in a centerfire caliber. One of the most curious things was that we designed the silencer in such a way that we captured the gas block inside the suppressor module. This allowed two things to happen at once that we liked.One thing was that it captured the leaking gasses from the gas block inside the suppressor. The other thing it did was allow us to make the internal volume of the silencer much larger. Did I mention that larger is better? There old adage that “there is no replacement for displacement” rings true not only in the car industry. This same adage rings true in the silencer world too.
This broke the boundary of suppression for this cartridge when we did this and made the best integrally suppressed 300 blk upper a distinct possibility for our Leonidas project. Do we know with absolute certainty that it is the best integrally suppressed 300 blk upper? No, because we can not possibly know where all these build reside nor do we have the ability to test them scientifically. But one thing is for cure, we had a winner with the original…
Enter the next evolution…
This build was well received for many years but we here at Liberty can not leave well enough alone and over time, Noah saw things he felt could use improvement with the Leonidas project and after much discussion the Leonidas Gen 2 was born! With the Leonidas Gen 2 we were able to shorten the over all length by 1.5″ thereby moving the center of gravity back some. We also updated the barrel with a tighter twist rate and length to better match more modern loads and heavy bullets at subsonic speeds. We also changed the supplier of the rail and upper housing to Aero Precision with their monolithic design with M-LOK support. All of this and we still shaving a whopping 9dB off of the sound signature! You have heard of the fictional guns that sound like a pneumatic stapler? This is one of those guns…
Here is another little tidbit that goes into these kinds of builds, we brought a lot of tech from the Gen 1 Leonidas over to the Gen 2 version, but we also made many updates to improve the weapon system overall. One such change is the gas block, we have long since made our own gas blocks for our Leonidas builds here at Liberty Suppressors, but with the Leonidas Gen 2 we sent a step further and add a gas adjust to the gas block so now you can tune the gas system to your specific cartridge for best performance overall.
All of this while still maintaining a single stamp footprint! It seems the best integrally suppressed 300 blk upper just got a whole lot better! Sop if you interested in one of the best integrally suppressed 300 blk upper designs out there, look no further than Liberty…
