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.

Rosco’s Bloodline 16″ 5.56 Heavy Barrel: This Rosco 16” 5.56 Heavy Barrel (HB) was made to cater to end users who need to run their guns hard without any remorse. The heavy contour barrel is well suited for full auto use and abuse.

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 rifle barrel you need, not just the one we want to sell you.
