From Half-MOA to 3 Inches: The Scope Rings Did It
A factory .243 that used to shoot half-MOA opened up to 3 inches. The barrel was fine. The scope rings had crushed the tube and snapped their keepers. Here is the fix, start to finish.

How Cerakote Works: The 9-Phase Process Behind a Finish That Actually Lasts
Cerakote is a ceramic polymer coating applied in 9 phases: disassembly, degreasing, masking, sandblasting, racking, gas-out, coating preparation, spraying, and curing. The finish lasts because of what happens before the coating is ever sprayed. Skipped prep steps are the reason most Cerakote jobs fail. A properly applied Cerakote finish on a firearm will outlast bluing, parkerizing, and any spray-on finish applied without correct surface preparation and cure. Who This Is For

How to Parkerize a Firearm: The Process, the Prep, and What Goes Wrong
Parkerizing is a zinc or manganese phosphate conversion coating applied to steel firearms at 185-195°F. The coating bonds directly into the metal surface, not on top of it. Surface preparation with aluminum oxide blast media is mandatory. Skip that step or polish the metal first and the coating will be thin, uneven, or fail to form entirely. Who This Is For This is for gun owners who want to understand the parkerizing process, restore a worn military or working firearm finish

Action Blueprinting and Ignition System Work: What Most Gunsmiths Get Backwards
Most rifles that come in with accuracy problems do not need a new barrel. They need the firing pin to strike the primer the same way every time. That is not what most customers ask for. It is not what most shops offer. It is the work that produces the largest accuracy gains on rifles that have already been accurized. Action blueprinting is what customers think they need. Ignition system work is what actually drops their groups. This post explains what action blueprinting actu

How Much Does a Custom Rifle Build Cost in 2026: A Real Breakdown from a Working Gunsmith
Most hunters who call Redleg about a custom build open with the same sentence: "I was thinking maybe $2,000?" That number comes from somewhere. Maybe they priced a factory rifle at a big box store. Maybe they talked to someone who bought a used hunting rifle and called it a build. Maybe they just guessed. Here is what $2,000 actually buys in 2026: a solid factory hunting rifle with no optic, no suppressor, no scope mounted and lapped, no ammo tested, no dope card, no zero con

How to Buy a Suppressor in 2026: The Complete Guide
If you have been waiting to buy a suppressor, 2026 is the year. The $0 NFA tax stamp changed everything. On January 1, 2026, the federal NFA transfer tax on suppressors dropped to zero. That single change sent 150,000 e-Forms into the ATF system on day one alone. If you are a Minnesota hunter trying to figure out how to buy a suppressor in Minnesota in 2026, this guide covers the full process from choosing the right can to getting it installed and zeroed.

What Actually Makes a Rifle Accurate? A Complete System Breakdown
Rifle accuracy is three systems working together: the mechanical rifle, the ammunition, and the harmonics that tie them. Most shooters chase one and ignore the other two. What each contributes, how they interact, and where to start when a rifle will not group.

Barrel Threading for Suppressors: What Actually Matters
Introduction: Threading Is Not a Simple Job Every week, rifles come into the Redleg shop that used to shoot well. The suppressor gets blamed. The ammo gets swapped. The optic gets checked. And the problem doesn't go away because none of those things caused it. In almost every case, the issue starts at the muzzle, and it started the day the barrel was threaded. Most shooters think barrel threading is simple. Cut threads. Screw on a suppressor. Done. Two customer rifles threade

Accuracy Guarantees Explained What They Actually Mean - And What They Don’t
“½ MOA Guaranteed.” You’ve seen it everywhere. It’s printed on rifle websites. Quoted at gun counters. Repeated online until it sounds like a universal truth. But ask ten shooters what an “accuracy guarantee” actually means and you’ll get ten different answers. That’s not an accident. In the firearms industry, accuracy guarantees are one of the most misunderstood and most abused marketing tools. Not because accuracy isn’t real, but because the way it’s presented often leaves

When a Rifle Suddenly SHOOTS BAD (Why my rifle won’t group)
A rifle that shot well last season and does not now has almost never worn out its barrel. The order to check it in: shooter, ammunition, optic and mounts, conditions, then the rifle. Work it backwards and you buy a barrel to fix a loose ring screw.

The True Measure of a Rifle Isn’t How It Shoots Dirty It’s How It Shoots Clean. Every precision shooter eventually learns the same painful truth: Barrels don’t lose accuracy overnight.

The Ultimate Guide to Thermal Scopes in 2025
Command the Dark Picture this: It's 2 AM on a sub-zero night in southwest Minnesota. The wind bites through your gloves, and the only sound is the crunch of frost under your boots.

The Science of Rifle Actions: Optimizing for Precision and Consistency. Part 1
I. The Rifle Action as a Dynamic Structure Every rifle action is a pressure vessel, a torque tube, and a resonance system all in one. The moment the firing pin strikes, the rifle transitions from static geometry to a dynamic elastic system steel flexes, vibrations travel, and forces balance across microscopic imperfections. Let’s break down what actually happens inside that split second: The firing pin accelerates at 10 to 15 feet per second, striking the primer with roughly

Behind the Bench: Lever Action Headspace Repair on a .30-30 Lever-Action Rifle
Some jobs start with a story. Others start with numbers that just don’t add up. A client brought in a new lever-action rifle that looked flawless but wasn’t shooting like one. The primers on his fired brass were backing out, and he wanted the rifle tightened, the chamber shortened, a trigger job, and a full Cerakote refinish. On the surface, it sounded simple. But when you measure everything, the truth shows up in thousandths of an inch. A Word of Caution For Lever Action Hea
