Rosco Manufacturing Bloodline Glock 43 Barrel



Product Description

The Rosco Manufacturing’s line of Glock barrels is a drop-in, match-grade option that enhances the accuracy and performance of any stock Glock pistol. All Bloodline Glock barrels are made from 416R stainless steel, broached, honed, polished, and then melonited.
All barrels have also been designed with strategic beveled edges surrounding the chamber area to reduce premature wear/ tear commonly found on basic aftermarket barrels. The result is a duty-capable upgrade that will not sacrifice quality. Drop a Bloodline in your Glock to experience true PERFECTION at a price that will leave you room for plenty of ammo.

This Glock Bloodline barrel is designed to work with Glock 43 pistols. Although this is a simple-to-accomplish user-friendly swap, we still encourage you to consult a local gunsmith should you have any questions about installation. This barrel is rated for use with SAAMI-approved, factory-new ammunition. Any catastrophic damage/failure caused to the product by improper installation, use of reloads, or non-SAAMI-approved ammunition will not be covered by the factory warranty. Compatible with Glock 43 and Glock 43X

No gunsmith fitting is required.
Made in the USA, the Rosco way!
