COSMETIC BLEMISH. Offering these 16″ Mid Length Barrels at a discounted price due to the variation of the Nitride at the muzzle end, after the Gas Journal. Please note the visual difference is pre-nitride, is purely cosmetic and will not affect fit or function. Please see photos for reference.
This 16″ M4 5.56 NATO Mid-Length barrel was designed around the USASOC specs for an Improved Upper Receiver Group with a little bit of the Rosco touch as well. The longer gas system allows for a smoother gas curve which leads to managed dwell times. This combo creates a great balance of speed and performance.

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

My experience has been good. Shipped timely, I ordered a blemished bloodline . I couldn’t find anything that would bother me about the finish where blemishes were. Barrel was machined smoothly and best of all it was dimpled for gas block! I put it on a BCM upper and it shoots beautifully tight groups. I can’t ask for more for what I paid for it! I will use Roscoe again for future builds!
