Thompson Center Arms Omega Muzzleloader Review

Send by email Printer-friendly version Share this

Thompson Center Arms (T/C) is perhaps best known for their muzzleloader rifles and accessories. Among their blackpowder offerings, perhaps there most lasting design has been the T/C Omega. For this review we'll be taking a look at the Omega in a stainless, synthetic stock configuration.

Currently the T/C Omega is offered in a variety of configurations. From synthetic to laminated stocks to thumbhole to standard straight stocks, the Omega has a variety of offerings. While the Omega is not as flashy as the newer Triumph, the Omega offers a full feature set for most modern muzzleloaders.

The Omega uses a 209 inline ignition system. The 209 primer is the same primer used in reloading shotshells and either a standard 209, 209M (magnum), or one of the various specialized blackpowder only 209 primers can be used. The inline system works by dropping down the trigger/hammer assembly to reveal the breech plug. Simply load in a 209 primer, close up the trigger/hammer assembly and the muzzeloader is ready to go. The breech plug can also then easily be accessed for cleaning and removal without removing the stock or using special tools. The breech plug can be removed with a standard 7/16" six sided socket.

Like other muzzeloaders, when you're ready to fire, simply cock the hammer back like a single action revolver. The Omega trigger is adequate and certainly good enough for the relatively short distances that most blackpowder shots are taken.

The Omega comes standard with Williams fiber optic three dot iron sights which are a noticeable improvement over standard buckhorn style iron sights. Under low light the sights glow faintly and are easy to pick up especially on a darker background. The rear sight is easily adjusted for windage and elevation by loosening a set screw that holds each direction in place.

The Omega uses adjustable Williams fiber optic sights.

Our review model came with a beefy stainless steel barrel. Stainless steel barrels are an important feature on muzzleloaders due to the hygroscopic nature of blackpowder and blackpowder substitute residue. In other words the burned powder residue attracts moisture and the stainless steel will corrode less easily than other steel types. The thick action and barrel are rated for magnum loads of up to 150 grains of powder that are becoming more common as muzzeloaders look for more range and accuracy.

The Omega comes with a strong aluminum ram rod that should give many years of use as long as it isn't misplaced or abused. The end of the ramrod is threaded and will accept adapters for loading various projectiles such as conicals and sabots.

The aluminum ramrod stores under the barrel.

Overall the Omega is a good inline muzzeloader offering. The drop away trigger assembly makes for simple cleaning and priming. Combine this with the solid ramrod, top notch iron sights, and a thumbhole stock and the roughly $500 street price is a good value for someone that is looking for a new muzzeloader to last season after season.

The Omega can accept a scope mount for use in states that allow optical sights during muzzleloader season.

TC is Great for Hunting

I has a TC from my Grandpa. but when upgrade you need to purchase some expensive part as muzzleloader so if you dont have much money dont upgrade! About Safest Way to Unload a Muzzleloader you can read here

TC Omega

I have had a TC Omega for a number of years now and it shoots great. I have taken a few deer with it and I really like the quality. TC was always easy to deal with and have treated me well over the years, including my TC Hawken flintlock that I bought 37 years ago. I would buy another one in a heartbeat.


I have an Omega. The trigger pull and accuracy are ok but not as good as my knights. The hammer on the Omega is a bit awkward to manipulate with gloves on and when cleaning the bore from the muzzle end with the rifle in a verticle position the drop trigger guard needs to be held in the down position with and elastic to keep it from rising up and hitting the ramrod. I feel that with the advent of Thompson Center's new easy to remove breech plug found on the Triumph and Encore, that the Omega is now out dated.

  I like the drop down


I like the drop down trigger mechanism as well as the fiber optic sights. 

I bought a TC Renegade 54 Cal muzzleloader about 25 years ago and still love it.  It is not as nice as this Omega but I'll keep my Renegade and not upgrade.

My Dad has a TC, and I have

My Dad has a TC, and I have shot it before.  Very nice guns, but unfortunately, when I purchased my muzzleloader, I had to worry about $$$$. Therefore, even though I wanted a TC, I had to settle for a CVA. 

Maybe I will upgrade in a couple of years, and if I do, it would definately be a TC.

TC is Quality

I love my TC bonecollector.  I think that it is one of the finest made guns that I own and highly recommend spending the extra dough.   Plus you get to hunt when their screamin!
