Briley .580'' Government Drop-In Bushing & Ring

The Briley .580" Government Drop-In Bushing & Ring is a precision barrel bushing designed for 1911 pistols that use the standard Government-size frame. If you're building or tuning a 1911 for the range or competition, a quality bushing is one of the first upgrades worth considering—it firms up the lockup between barrel and slide, reduces wear on both, and can tighten your groups. Briley is known for exacting tolerances, and this spherical bushing is made to drop in without requiring gunsmithing.

A Government-frame 1911 (full-size, not Commander or Officer) needs a bushing that matches both the frame size and the barrel diameter. The .580" specification means this bushing is sized for barrels with that nominal diameter. Because it's a drop-in part, you simply remove the old bushing, install this one, and you're ready to function-test—no reaming, honing, or fitting required, though a good hand-fit check is always smart before firing.

Whether you're running a stock Government-model 1911 or a custom build, a tighter barrel bushing can improve consistency without altering the gun's reliability or ergonomics. It's the kind of incremental upgrade that serious 1911 shooters know pays dividends over time.

Frequently Asked Questions

Will this Briley bushing fit my 1911?

This bushing is made for Government-frame 1911 pistols and is sized for .580" barrels. Confirm your frame size (Government, Commander, or Officer) and barrel diameter before ordering. If you're unsure, verify against your current bushing or check your 1911 documentation.

Do I need a gunsmith to install this drop-in bushing?

No—it's called a drop-in bushing because it's designed to be installed without honing or reaming. Remove your old bushing and install this one. That said, a visual check to ensure a clean fit before shooting is always good practice.

What's the difference between a spherical bushing and other types?

A spherical bushing (also called a ball bushing) has a rounded, recessed seat that allows the barrel to center itself more evenly against the slide. This geometry is known for durability and improved lockup compared to flat-seated designs.
