URX Barrel Nut Wrench for URX II/3/3.1 and SR15

This purpose-built tool is CNC machined for a precise fit with URX II, URX 3, URX 3.1, and 11-tooth barrel nuts commonly associated with a certain well-known manufacturer (if you know, you know). Made in the USA, it’s engineered for professional use in demanding setups.

Constructed from 7075 aerospace-grade aluminum, this wrench is designed to prevent marring OEM barrel nuts while remaining exceptionally strong and lightweight. It features an open-ended design, allowing for convenient installation and removal without disassembling your muzzle device or gas block—even if your muzzle device is pinned and welded.

Finished in H-Series Cerakote Graphite Black, it offers excellent abrasion resistance, corrosion protection, and a clean, professional look.
