If I am going to the expense of building a rifle thats going to be expensive to start with I will not skimp on the most important part of that rifle...I only use Lother Walther barrels on my sporting guns..but Krieger, Lilja and Douglas are good..I don't want anything to do with Shaw or A&B barrels..Some shoot and some don't, if you get lucky then your good to go, if your unlucky then you have to buy another or whatever...
