I need .243, 25-06, or 7mm08 bull barrel for my NEF SB2. I will purchase or trade my 280 remington for one. Also looking for thumbhole stock for NEF. Willing to pay around $100 or less for one.

Have you lookled here?

Thats gonna be a difficult task for a laminated version. Call H&R and if they've got one in stock, have it shipped to your door at $122 for the set.
