Modern Defense, LLC

🇺🇸 Walking through the rooms of sacrifice, where every artifact whispers the fury of battles fought and lives forever changed. From the Revolutionary War’s fight for independence, through the Civil War’s American-against-American hell, to every conflict since — World Wars, Korea, Vietnam, the Middle East, and beyond — millions answered the call so we could walk free.

Each name, each story, each single life lost represents a debt we can never fully repay. One soul. One mother’s child. One father’s son or daughter. Gone, so that tyranny would never silence our voices or chain our future.

For 250 years, their blood has watered the tree of liberty. Because of them, we wake up in a nation of peace, opportunity, and God-given rights instead of fear and oppression.

We must remember. We must reflect. We must honor — not just with words, but with how we live.

Never forget the cost of freedom. Never take it for granted.

🚨 Colorado Gun Owners & Hunters – This Hits Different!

This classic Browning BAR II in 7mm? Just 3 rounds and a magazine impossible to “rapid reload” vs. a modern AR-15 DPMS Kitty Kat 300 BLK..

Yet, both get treated the exact same by Aug. 1 under SB25-003: In-person fi****ms safety course (multiple hours/days), background checks, fingerprints, sheriff’s eligibility card, fees… lots of red tape.

If you’ve been eyeing that hunting semi-auto or any specified semiautomatic rifle you actually want – get it before August 1.

After that? Be ready for the application + training grind. Don’t say we didn’t warn you.

What’s exempt:
-Lever-action fi****ms
-99% of pump-action shotguns
-99% of bolt-action fi****ms
-99% of handguns
-99% of .22 LR rifles without a separate upper/ lower

*(Reason for the 1% is FDD had 1-3 fi****ms in those categories on their prohibited draft list and we are waiting to find out if they remain or taken off in the official July 1 list — This included Desert Eagles, Q Fix Bolt fi****ms, a RIA VRPA40 along with certain R***r 10/22 rifles without a separate upper & lower receiver).

Just tried shouldering this beast of a .50 Cal Barrett for the first time… and yeah, she humbled me real quick 😂

I’ve fired plenty of guns way bigger than I am, but this monster kicked my butt before I even pulled the trigger. Absolute respect to Charlie for making it look easy — He shoulder-fires the 50 BMG like it’s nothing. Legend.

If you think you’ve got what it takes to tame this cannon (or just want to blast some other machine guns), come out and step up to the challenge! We’ve got the Barrett, a full lineup of machine guns, and a ton more ready to go.

I actually had a very normal childhood, but you’d never know it LOL.. My dad definitely made life interesting— Take his jeep for example.. It started with one innocent license plate and suddenly he’s flooring the gas on an idea with zero brakes. Full send. No permission. Pure freedom. My mom was the best 🥰

• Roof? Deleted in a single Sawzall weekend. “It was holding me back from my dream”
• Twin .50 cal deuces on top? “Because one is not enough, obviously” 💥
• M60 riding shotgun because the passenger seat belongs to freedom now
• Celluloid-operated mini gun up front… because nothing says ‘morning coffee run’ like 4,000 rounds of pure American motivation☕

This is peak America, folks: one man, one wild idea, and the God-given right to turn his Jeep Wrangler into a mobile fortress without asking permission. Land of the free, home of the tactically unhinged🐉

Love you anyway, dad — never change. You’re living the dream.

🔥 Much Needed Mag Change Reps with Heretic Customs 🔥

Just put a rifle through its paces (getting in mag changes I don’t practice enough) and damn… it runs flawlessly. Butter-smooth cycling, zero hiccups, and feeding like a champ. Literally no seating issues or malfunctions. If you want a rifle that just works every single time, this is it (find in store or build your own on their website).

Threw on a RC2 and a .us suppressor cover for some real workout reps. Absolute game changer. If you’ve ever accidentally grabbed the can mid-string, you know the benefit of zero burn gear.

Of course I had to show off the U-Can too — Because, we are now stocking these in store at ! Battery-free, secure, and the perfect way to transport and store everything when it’s time to pack up.



(Shoot on the range in Colorado Springs for only $15/person/day at - No memberships)

First time running the Hesychia SixK suppressor… and damn. 🔥

Sorry to the crew for constantly mixing you up with your sister company — my bad for getting the names intertwined! You are two separate but badass veteran-led brands and I’ll get it right going forward.

That said… this thing is legit. First round out of the can and the sound reduction was immediately noticeable — way quieter than I expected. Gas blowback was nonexistent!

Huge thanks to the IDG team for creating a great product—Respect.
