Our Rosco Melonited Bolt Carrier Groups are designed to meet the modern-day carbine shooters requirements. 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.

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.

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.
