    Been wanting this barrel length for some time. Got lucky and found it in stock on Big Tex so I ordered it without hesitation. Barrel is quality!

    This is my second SOLGW 13.7in barrels. The first was just a pin & weld using a NOX muzzle device. This second barrel had a FSB installed and another NOX muzzle device pinned. I am very happy with both barrels. Big Tex had this to me very quickly as usual.

    Great barrel, looking forward to using it in my build. Big Tex Outdoors is the best retailer out there—GREAT customer service!
