Description

This 12.5” Rosco barrel is designed to bridge the gap between SBR-Pistol and/ or RECCE platforms and delivers amazing precision performance for its compact size. It is the perfect addition for the person attempting to create the ultimate intermediate patrol platform.

The Rosco 5.56 (NATO) barrels are designed to meet the modern day carbine shooters requirements. We are a long way from our daddy’s “Sporter” AR, and those specs just won’t cut it anymore. From properly managed dwell times for SBR’s, to running Suppressed, or setting up a balanced patrol carbine Rosco has incorporated your needs into their engineering. They have successfully accomplished this by picking the right twist rates, gas port diameters, and barrel materials according to the barrel they are making (not a lazy blanket method). They also balanced input from consumers and military end-users in order to bring you the product you need, not just the one they want to sell you.

Rosco bloodline

I was definitely impressed when I first got the barrel. For the money it's a good looking barrel. Haven't built it out yet, but it's a sub 200$ barrel sold by a reputable mnfg so I'm sure it's good to go.
