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.
Our 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 we have incorporated your needs into our
engineering. We have successfully accomplished this by picking the right
twist rates, gas port diameters, and barrel materials according to the
barrel we are making (not a lazy blanket method). We have also balanced
input from our consumers and military end users in order to bring you
the product you need, not just the one we want to sell you.
