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, 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.

This Rosco 16” 300 Blackout (300 BLK) barrel is perfectly suited for carbines shooters that plan on running only supersonic ammo, or are building a well-balanced hunting platform.

Our Rosco 300 Blackout barrels were created by using input from SOCOM end users and some of the original creators of the 300 Blackout caliber. Every barrel was designed to optimize the original role for this caliber; to be suppressor friendly and accurate. It is our goal to get you the performance that you seek out of these barrels when running sub-sonic ammo or supersonic ammo (depending on barrel length). Twist rates, gas port diameters, and lengths have all been taken into account when we set out to make these. Let’s just say that we don’t like leaving things to chance.

    I have bought 4 barrels from this company. They are great. Good materials, sleek design and a prime example of craftsmanship. Each of my barrels has over 3k rounds of testing and I have not had one single issue. These guys make a great product.

    I bought the 16 bloodline 300 black out and paired or with their BCG for my build. Put a suppressor on it and wow. This set up is amazing. The groups I get with it are great!
