204 Ruger AR-15

The 204 Ruger AR-15: The Ultimate Coyote Slayer!

Are you tired of those pesky coyotes wreaking havoc on your backyard? Do you want to take your revenge by hunting them down like a pro? Look no further than this Redleg Co .204 Ruger AR-15!

Why the 204 Ruger for Predator Hunting

The 204 Ruger exists for one job: putting very fast, very light .20 caliber bullets on small targets with almost no recoil. Hornady and Ruger introduced it in 2004 as a dedicated varmint cartridge, and factory loads are among the fastest production ammunition you can buy. For coyote and prairie dog work that combination means a flat trajectory that forgives ranging errors, minimal wind drift for such a small bullet, and so little recoil that you can watch your own hits through the scope instead of losing the target in recoil.

That last part matters more than most shooters realize. On a called coyote stand, seeing your impact tells you instantly whether to follow up or move on. A cartridge that lets the shooter self-spot from an AR platform, with fast follow-ups available, is a genuine field advantage over harder-kicking calibers, and it is why the 204 has held its place with serious predator hunters twenty years on.

The Build Sheet

The component choices follow the mission. The 24-inch PacNor barrel wrings the full velocity potential out of the cartridge, which is the whole reason to shoot a 204. The nickel boron bolt carrier runs cleaner and slicker through a high-volume prairie dog shoot than a standard phosphate group. The adjustable gas block lets the rifle be tuned to the load so ejection and recoil impulse stay consistent, and the MBA-1 stock gives a stable cheek weld for the precise shots this cartridge is built to make.

This bad boy is loaded with everything you need to take down those pesky critters. From the Spikes upper and lower, to the 24-inch Pacnor polygonal cut barrel, this AR-15 means business.

And let's not forget about the Fail Zero nickel boron bolt carrier group - it'll withstand anything those pesky coyotes can throw at it! The JP Enterprises buffer system ensures that every shot is as smooth as silk, while the CMC 3 lb straight trigger will make sure you don't miss.

But what about comfort, you ask? Fear not! The CAA Grip will make sure your hands don't slip, while the Luth AR MBA-1 Stock will keep you comfortable even after hours of hunting.

And the Seekins adjustable gas block means you'll have pinpoint accuracy, every single time. Speaking of accuracy, the Leupold M4 scope base and Leupold 6.5-20 scope will ensure that no coyote is safe within a hundred yards of you.

But let's be real, looks matter too. That's why this rifle features a riptile Cerakote paint job - it's both stylish and badass.

So, what are you waiting for? Get yourself the 204 Ruger AR-15 and be the ultimate coyote slayer in your neighborhood! (Just make sure you know the local hunting laws first...)

Frequently Asked Questions

Is the 204 Ruger good for coyotes?

Yes, with appropriate bullets and realistic distances. The 204 delivers flat trajectory and almost no recoil, so you can spot your own hits and follow up fast from an AR platform. Bullet selection matters: heavier .20 caliber offerings in the 39 to 40 grain class are the usual choice for coyote-sized game, while the lightest varmint bullets are better kept for prairie dogs.

Why a 24-inch barrel on a varmint AR-15?

Velocity is the entire personality of the 204 Ruger, and barrel length is how you keep it. A long barrel wrings the full speed potential out of the cartridge, which flattens trajectory and extends the distance at which the bullet does its job. On a rifle that gets carried to a stand rather than through timber, the extra length costs little and returns a lot.

Why does a varmint AR need an adjustable gas block?

Consistency. An adjustable gas block lets us tune the action to the specific load the rifle shoots, which smooths recoil impulse, keeps ejection consistent, and helps the shooter stay on target through the shot. It also gives room to re-tune if a suppressor goes on later, since a can changes gas behavior in any semi-auto.

What does a custom varmint AR build cost at Redleg?

Custom builds at Redleg run from $2,500 to $15,000 depending on components, and a dedicated varmint AR in this configuration sits toward the lower-middle of that range. Every build is quoted individually against your component list, and every one leaves with load development and a verified zero.
