Build philosophy

A Rifle That Has to Do Three Jobs.

Jon's PRS rig is a 25-pound, purpose-built 6 Dasher in a KRG C4. He loves it. He also doesn't carry it up a mountain. This rifle is the other half of the answer — and the way it got designed says a lot about how Jon thinks about rifles in general.

The constraints were stacked up before any part went on the order sheet. The rifle has to cover three contexts — his primary line of work, the teaching he does at The Cadre, and the NRL Hunter matches he competes in — without rebuilding the platform between them. That means one chassis, one set of ergonomics, one trigger reach. It also has to live inside the 16-pound cap that NRL Hunter teams and open heavy run on, which means every gram of comfort gets paid for somewhere else.

So the build order isn't accidental. The action came first because the action is the anchor. The barrel came next because weight savings up front buys you everywhere else. Then the platform got built around the two of them. Walk through it with me.

The constraint

Everything Has to Fit Under 16 Pounds.

The weight cap is the whole reason this build looks the way it does. Jon never puts a total weight on the rifle on camera, so there's no tally here — just the budget, and which calls bought room versus spent it.

Class limit ≤ 16 lb NRL Hunter Open Heavy / Teams limit

Jon never states the rifle’s total weight or any single part’s weight on camera.

Bought room up front
  • Carbon barrel Proof carbon-wrap sheds weight up front so heavier parts can stay on and still make the cap.
  • Whiskey 3 Pro chassis Same C4 ergonomics in a lighter package — the reason Jon can run it in NRL Hunter at all.
Kept, despite the cost
  • OEM Ckye-Pod Triple-pull kept stock — no fat trimmer, no carbon legs — and still made weight.
  • KGM R30 can A can adds ounces at the muzzle; the light front end is what lets it ride along in spec.
Piece by piece

Every Component, Explained.

Eight parts, three acts. Each one with the reason it's on the rifle, the tradeoff Jon accepted to put it there, and a jump to the spot in the video where he talks about it.

Act I

The Barreled Action

The action is the anchor. Pick it first, because everything else gets built around it. Once the action's set, the barrel is where you buy yourself room to breathe on weight — and weight is the whole conversation on a Hunter gun. Get these two right and the rest of the rifle is a series of smaller arguments.

  • Swappable bolt face

Zermatt Arms TL3 Action

Affordable, reliable, and modular enough to chase different cartridges.

Around $1,100, picked up two or three years ago. The TL3 has been the through-line of this build since day one — same action, same recoil lug, same bolt body. Jon wanted something that accepted prefits and let him swap bolt faces between cartridges without buying a second action. Two-plus years in, that's exactly what it's done.

It runs smooth. It's been reliable. The integrated recoil lug means one less thing on the spec sheet to worry about. For the money — somewhere around $1,100 when he bought it — it punches above its weight for a rifle that isn't trying to be a single-purpose match gun.

Why it's on the rifle
  • Prefit-barrel compatible
  • Swappable bolt face for different cartridges
  • Integrated recoil lug
  • Reliable and consistent over ~1,600 rounds
The tradeoff

The top rail isn't integral — it's set in with screws. Hasn't been an issue for Jon, but if he were buying a custom action again, an integrated rail would be on the spec sheet.

Proof Research Carbon Fiber Barrel
  • Proof carbon prefit
  • 24" · 1:8 twist
  • 6.5 Creedmoor
  • ~1,600 rds
02 · The shot
02 · The shot

Proof Research Carbon Fiber Barrel

24-inch, 1:8 twist, 6.5 Creedmoor — chambered prefit.

Just shy of 1,600 rounds. Same barrel since the build came together — about two years on it now. 24 inches, 1:8 twist, the typical Proof prefit go-to — and the single biggest reason the front end is light enough to absorb a suppressor and a triple-pull bipod without busting the 16-pound cap.

You'll hear that carbon-wrap barrels walk after five, six, seven rounds on a string. Jon hasn't seen it. He ran this same barrel up at Brian Morgan's Hat Creek last year on higher-round-count strings and shots didn't open up on him. That doesn't mean it can't happen on yours. It means it hasn't happened on his.

Why it's on the rifle
  • Saves weight up front
  • Repeatable groups out past stage distances
  • Compatible with TL3 prefit thread spec
The tradeoff

Carbon-wrap barrels have a reputation for walking on extended strings. Jon hasn't experienced it on this barrel, but it's worth tracking on your own logbook before trusting it on a match day.

Act II

Driving It

With the barreled action set, the next four pieces are about how you actually run the rifle — what you hold, what you look through, what's keeping the gun honest, and what's coming off the muzzle. These are the parts that have to work across teaching, work-line stuff, and matches without being reconfigured every time. Jon's running one set that has to do all three.

KRG Whiskey 3 Pro Chassis
  • KRG Whiskey 3 Pro
  • Folder
  • Full-length ARCA

03 · The platform

KRG Whiskey 3 Pro Chassis

The C4's ergonomics in a configuration light enough to carry up a mountain.

Jon shoots KRG because Phil put him onto them. “I started shooting KRG chassis because Phil highly recommended them,” and it was apparent the second one was in his hands — nothing but excellent, great customer service, great people to work with. That's the through-line behind the whole platform.

This rifle started life in a KRG X-Ray and moved into the Whiskey 3 Pro for one reason: the ergonomics map almost exactly to the C4 Jon shoots in PRS. Same hand feel, same trigger reach. The fewer things that change when the use case changes, the less he has to relearn between matches.

Toolless cheek riser, comb height, butt-pad height, length of pull. That matters in two places. One, on the line — when something feels off, he can fix it without breaking out a screwdriver. Two, at a class — he can show a student what an incorrect LOP feels like, or what it feels like when the comb is jammed so high you're slamming your face into the butt pad, without disassembling anything to demo it.

The folder shrinks the airline case. The full-length ARCA on the forend means he drops the rifle on an Anvil 30, or any other ball head, without hunting for a sweet spot. Bipods slide. Nothing has to come unmounted to reconfigure the gun for the next stage.

Why it's on the rifle
  • Same ergonomics as the PRS C4
  • Folder shrinks the airline case
  • Full-length ARCA — drop and shoot on any tripod
  • Toolless adjustments make for clean demos
  • Enclosed forend drives well off bags
The tradeoff

Modular comes at a small weight cost vs. a stripped-down dedicated stock. For Jon, the tradeoff is worth it — he uses the same platform for work-line stuff, teaching, and matches. If you only ever do one of those, simpler might serve you better.

Kahles K328i — SKMR4+ Reticle

The 2026 refined model, borrowed from Phil for this match.

Borrowed from Phil for the match. Jon's been running the K525i on his PRS rifle for a couple of years, so jumping to a 328 with the same reticle family is a known quantity — he isn't relearning the tree under pressure. Kahles refined the 2026 line based on shooter feedback; Phil's breakdown video covers exactly what they changed.

The SKMR4+ does the thing Jon wants a competition reticle to do: hold when you want them, get out of the way when you don't. A lot of the over-built reticles on the market feel cluttered the moment a target gets small. This one stays readable when the steel does.

One note for replicators: Jon doesn't call out the magnification range, tube diameter, or focal plane on camera, so those aren't listed here — pull them off the spec sheet before you order.

Why it's on the rifle
  • Familiar reticle from the K525i
  • Reticle holds without overwhelming the FOV
  • 2026 refinements address shooter feedback
The tradeoff

It's a borrowed optic for this match — the long-term setup will dictate whether this is the right glass for the new build coming from Redbeard Gunworks.

Badger Condition One + Flatline Ops Halo X

Diving board mount for optionality. A level that settles instead of hunting.

The Badger Condition One carries a diving board out front. Jon isn't running a weapon-mounted laser RF — a Fire 4000, a Mars, that kind of unit — on this match. He and Greg are spotting and ranging as a team. The board is there so when the rifle comes back to solo work, a unit can bolt on without a re-zero. Optionality, paid for once.

The Halo X has been on Jon's rifle for a few years and the reason is simple: when you adjust your cant, it settles fast. It doesn't keep moving after you stop the gun. He's used levels that were slow to correct — they tempt you into overcorrecting because you can't read where the bubble actually wants to live. That's a habit you don't want to build.

Why it's on the rifle
  • Diving board adds laser RF without a re-zero
  • Halo X reads fast and stops moving
  • Streamlined enough to stay out of your sight picture
The tradeoff

You're paying for capacity you may never use. If you'll never run a weapon-mounted RF, a cleaner one-piece mount drops a couple ounces and a couple hundred dollars.

KGM R30 Suppressor

"I'll never go back to a muzzle brake."

Jon picked up the R30 not long after moving to Texas. Six or seven months in, the comparison is settled. He'll never go back to a muzzle brake.

There's no brake on the end of it, so it isn't doing what a hybrid does for recoil reduction. Doesn't matter. Even in a lighter NRL Hunter configuration, on a 6.5 Creedmoor or a .308 — anything with a little more recoil than your typical 6mm — the impulse stays manageable. What he keeps coming back to is what the can buys around the recoil number: with a can, you can talk to your spotter. Your partner doesn't flinch every time you break the shot. You're not married to earpro all day.

Jon doesn't run earpro under the can in open terrain. He'll put it back in if he's shooting somewhere with an overhang and it actually gets loud. Read the room — and check your local laws.

Jon doesn't state the can's length, weight, or caliber rating on camera, so those aren't listed here — confirm them against KGM's spec sheet before you build to weight.

Why it's on the rifle
  • Manageable impulse on a 6.5 CM or .308
  • Communication on the line stays clear
  • No earpro pressure all day in open country
The tradeoff

Not as much recoil reduction as a hybrid brake-can. If you need the rifle flat and quick for fast pairs, a hybrid is worth a look.

Act III

Match-Day Support

The last two pieces are the ones every stage runs through — the bipod that has to catch whatever angle the terrain throws at you, and the load that has to put a round on a small steel plate at an unknown distance and not miss. Get these wrong and the rest of the rifle doesn't save you.

MDT Ckye-Pod — Gen 2 Triple-Pull

OEM configuration. No fat trimmer, no carbon legs.

Second NRL Hunter match running the triple-pull. Jon set this rifle up to make weight with the Ckye-Pod in its OEM configuration — no fat trimmer, no carbon legs, nothing trimmed off the bipod to keep the whole package under the 16-pound cap.

Hunter terrain throws curveballs. Stages get built around rocks, prop edges, awkward bipod-to-ground distances you can't always plan for. Jon enjoys natural terrain that forces you to figure things out on the clock — and triple-pulls are the right tool when you don't know in advance how tall you need to be.

Why it's on the rifle
  • Massive elevation range for terrain you can't scout
  • In-spec for the 16 lb cap with no upgrades
  • Familiar UX to anyone shooting MDT in PRS
The tradeoff

Heavier than a single-pull bipod. If you know your stage will be prone or near-prone, a stripped-down bipod saves the weight.

Hornady 147 ELD-M Handload

Lapua brass, H4350, sitting around 2,753 fps.

147 ELD-M projectiles in Lapua brass over H4350. Jon runs it right around 2,750 — “2753 is usually where I'm sitting.” The groups are honest, the SD and ES numbers are clean off the chrono, and he shot it last week at a one-day NRL Hunter Games as a tune-up — no elevation surprises across the whole day.

This is the load that goes into the match. If anything is going to change between now and the next build, it's the platform around the load — not the load itself.

Why it's on the rifle
  • Proven group sizes
  • Clean SD/ES on the chrono
  • Validated on a recent match
  • Repeatable with components that are still findable
The tradeoff

Handloads aren't transferable. If you don't reload, factory 147 ELD Match is a reasonable starting point — re-validate everything on your gun.

Buy once, cry once — but we also completely understand this stuff can get expensive. Do your homework before you pull the trigger.

What's next

A New Build is Coming from Redbeard Gunworks.

Two-plus seasons on this configuration sharpened what Jon would want in a next build. The TL3 has been reliable — it's never given him trouble — but the non-integral top rail is the kind of thing he'd spec differently if he were buying a custom action again. Integrated rail, integrated recoil lug, full stop. The Proof carbon prefit has held up well enough that the carbon-fiber-walks-on-you internet wisdom doesn't reflect his logbook. The chassis, the optic family, the level, the can, the bipod, the load — Jon expects all of it to largely carry over. None of it is broken.

What changes is the barreled action. Jon's running NRL Hunter teams with Phil this season, and the crew at Redbeard Gunworks has something in the works for that campaign — a refined version of the same answer to the same question: one rifle, one set of ergonomics, configured to handle his work, his teaching, and his matches without rebuilding the platform between them.

That's the real takeaway here. The next rifle isn't a reinvention. It's a sharper edit of a build that's already working. The parts you keep say as much about how you think about rifles as the parts you change.

If you're at Snake River, say hi. Jon says chances are you won't recognize him — and that he's friendlier than he looks.
