Rosco Manufacturing Bloodline Glock 17 Barrel



Product Description

The Rosco Manufacturing’s line of Glock barrels are 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 17 pistols, generations 1 through 4. Although this is a simple to accomplish user-friendly swap, Rosco still encourages 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.

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

Bought the Rosco barrel for my Gen 3 G17. Throughout 250 plus rounds I’ve been experienced failures to feed, failures to eject, and the slide failing to go back into battery without assistance and excessive wear on barrel itself (including the nitride finish coming off in certain areas).

Expected more from Rosco given their reputation. This barrel has been a complete disappointment. Switched back to the factory barrel.
