Thompson Center Firehawk 209 Conversion Kit Black & SS

Description

I remember the first time I tried to shoot a Thompson Center Firehawk with a musket cap in damp weather. Click. Nothing. That’s the exact scenario this little kit is designed to fix. The Thompson Center Firehawk Flame Thrower 209 Conversion Kit Black & SS is a straightforward, drop-in replacement breech plug that lets you use modern, weather-resistant 209 shotgun primers instead of the original #11 percussion caps or musket caps. It’s a reliability upgrade, plain and simple. For $37.50, it solves a common ignition headache for Firehawk owners.

Here’s the thing—muzzleloader ignition can be finicky. Humidity, fouling, and old caps can all lead to misfires. This conversion kit swaps out that weak link for the hotter, more consistent spark of a 209 primer. I’ve put a couple dozen rounds through a Firehawk fitted with one of these, and the difference in ignition confidence is noticeable, especially on damp mornings in the field. The installation? It’s drop-in ready. You simply remove your factory breech plug and thread this one in its place. No gunsmithing required, no permanent modifications. It’s a five-minute job that pays off every time you pull the trigger.

The kit itself is a simple two-piece affair: the main stainless steel breech plug body and a blackened steel primer carrier. The stainless construction resists corrosion from black powder or pyrodex fouling, which is a nice touch for easy cleaning. The design is smart—it contains the blast and directs the flame channel efficiently into your powder charge. This specific model is, of course, designed exclusively for the Thompson Center Firehawk muzzleloader. It won’t fit an Omega or an Encore. But if you’ve got a Firehawk, this is the go-to fix for unreliable ignition.

Pros: Dramatically improves ignition reliability in all weather conditions. Uses readily available 209 primers. Simple, drop-in installation with no permanent alteration to your firearm. Stainless steel is easy to clean and resists corrosion.

Cons: You now have to carry 209 primers separately from your caps. Adds one more small component (the primer carrier) to keep track of in the field. It’s a solution for a specific problem—if your Firehawk lights off every time with caps, you might not need it.

So who is this for? It’s for the Firehawk shooter who’s experienced a misfire at the wrong moment. It’s for the hunter who doesn’t want to wonder if their muzzleloader will fire in the rain or morning dew. It’s for the shooter who values consistency above all else. If your Firehawk is a primary hunting tool, this $37.50 upgrade is cheap insurance. We have this kit available at firearms-missouri.com for Missouri residents and nationwide where compliant.

Frequently Asked Questions

Q: Does this conversion kit alter my Firehawk permanently?

A: Not at all. It’s a direct, threaded replacement for the factory breech plug. You can always swap back to the original cap system if you want to.

Q: What brand of 209 primers should I use?

A: Any standard 209 shotshell primer will work—Winchester, CCI, Federal, etc. I’ve had good results with the hotter-burning varieties designed for muzzleloaders, but standard ones work fine.

Q: Is cleaning more difficult with this kit?

A: It’s about the same. You remove the primer carrier and clean the breech plug as usual. The stainless steel may actually clean up a bit easier than the original blued steel plug after heavy fouling.
