The 15/16" barrels can be modified to fit your Lyman Great Plains rifle, at extra cost by a gunsmith - after shipping the stock assembly to Track Of The Wolf. When you reach this site, pick out the 15/16s you want - retrieve the product number - then call the website by phone& ask to speak to a gun tech. Tell him what you have & how to go about getting her fitted. Also ask if you can return to using theLyman barrels after all this inletting/stock-cutting is done. My guess would be .... No!
