Bloodline 16″ 300 Blackout Barrel

From: Original price was: $206.00.Current price is: $99.00.

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.  NOTE: These barrels are engraved ‘HEAVY’ for our end users in restrictive states.

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.

    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!

    I am a AR15/M4 Armorer and FFL dealer… so I have not even shot this barrel but I want to say those manufacturers that dimple the barrel for you are a Godsend! Keep doing what you’re doing!! Barrel install/Gas block install was a breeze!

    Made an order. Shipped when it said, quality was great. I even requested a phone call on a particular item and got a call back the same day. This is the way business is supposed to be done!!! Thanks Rosco!!!!
