🙋 Sons Of Liberty Barrels – FAQs
Q: What’s the difference between .223 Wylde and 5.56?
.223 Wylde barrels allow you to shoot both .223 Rem and 5.56 NATO safely and more accurately, especially with match ammo.
Q: Are these barrels chrome-lined?
No. SOLGW uses QPQ nitride treatments for enhanced wear and corrosion resistance without sacrificing accuracy.
Q: Can I pin & weld a 14.5” SOLGW barrel?
Yes. We carry muzzle devices like the NOX that make your build compliant when pinned & welded to 16”.
Q: Do these barrels require special bolts or carriers?
No. All SOLGW barrels work with standard MIL-SPEC BCGs, but we recommend pairing with a SOLGW BCG for best performance.
