Melonite Gas Tubes

Our Rosco Melonite Gas Tubes have an extremely durable Black Nitride finish that increases corrosion resistance, wear resistance, fatigue strength and cosmetic appeal. These gas tubes work great under a handguard because they are more durable than standard gas tubes. Available in pistol, carbine, patrol length, mid-length, and rifle lengths. Does not include a roll pin.

Non-Adjustable Gas Block

Our Rosco Non-Adjustable Gas Blocks are purposely designed to be lined up perfectly with our barrels and gas ports to ensure reliable cycling every time. We have created two options for the end user; Our Non-Adjustable gas block is a direct plug in for any one of our barrels and has provisions for pinning, our Adjustable block picks up where our standard block leaves off and works perfectly for shooters that want to be able to control their gas flow for suppressed applications.

Contract/OEM Overrun 12.5″ Barrel.  We re-engraved this barrel so we can offer with our full warranty. We are calling this a blemish due to the re-engraving.  Bottom of barrel is laser engraved ‘Powered by Rosco’.  Note: Does not come with standard Rosco packaging. 

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.
