$150-$75 seems a little high to me, the reason you're replacing them is you don't much care for the "accu trigger) and want to up grade the barrel (maybe even a different caliber), but most guys putting a new trigger on their rifle, want to up grade also, along with the barrel. I'd say you're going to have an easier time selling the barrel than the trigger. You may be better off selling as a package. On accurateshooter.com you'll find a lot of take off barrels etc. for sale by members, I ran up on this one:
1- 22-250 off of factory savage axis 22". -$50.00 (Sporter Contour)
1-Savage Hog Hunter .308 20" removable iron sights and threaded 5/8x24 tpi $100.00 (Heavy Varmint contour)
2-Savage AXIS 20" .308 threaded 5/8x24tpi $75.00 (Sporter Contour)
Now, I realize this isn't exactly what you are trying to sell, but I think you see my point regarding the price, as that is the crux of your question. Hope this helps.
