Melonite Gas Tubes

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, v2

Our v2 Non-Adjustable Gas Blocks feature the same 'Bloodline' dependability, with improvements for the modern shooter.  We added a knockout hole at the front of the gas block to aide in removing the gas tube. Also featuring improved tolerances and finishes, making the v2 Gas Block a staple for years to come.

Adjustable Gas Block

Our Rosco Adjustable Gas Block is purposely designed to be lined up perfectly with our barrels and gas ports to ensure reliable cycling every time. These Adjustable gas blocks pick 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.

Bloodline 7.5″ M4 5.56 NATO: This Rosco 7.5″ M4 5.56 NATO Bloodline Barrel is designed to be the perfect addition to any SBR or Pistol build. This barrel was designed to perform suppressed and be accurate. ALL NFA RULES APPLY!

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 selecting the right twist rates, gas port diameters, and barrel materials according to the barrel we are making rather than a one-size fits all approach. We have also balanced input from our consumers and military end users to bring you the product you need, not just the one we want to sell you.
