Help with Knight ML value?

[Texas by God]

I’ve been offered a .45 caliber Knight Disc bolt action muzzleloader in trade. It has a black plastic stock with a high Monte Carlo comb, palm swell pistol grip, and Schnable forend. The barrel is blued and fluted. Can someone provide a ballpark value for this rifle? The metal is in very good condition and the stock has a few slight marks but nothing bad. Any help is appreciated!

Finding the discs used to be hard. Find out if they are readily available before trading. They are good for 2 shots at most.

Is that a Knight Disc Extreme .45 cal? Thumbhole stock? I have the 50 cal. without the thumbhole. I don't think the .45 cal is as wanted as .50 cal. or bigger. They are accurate. I would say it's worth $150.
Here's some other info about them: Serial number change for the .45 twist rate was anything prior to #2291 on mild steel and #5043 on stainless were 1:20 twist.
All the other DISC based Knight 45s are 1-30 twist except the 45 Target model.

They are easy to buy Sportmans Den or muzzleloaders.com has them. There are 2 different types depending on the system but run about $11 per 100
