Rosco Manufacturing 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 Rosco has incorporated your needs into their engineering. Rosco has successfully accomplished this by picking the right twist rates, gas port diameters, and barrel materials according to the barrel they are making (not a lazy blanket method). They have also balanced input from their consumers and military end users in order to bring you the AR15 Barrels you need, not just the one they want to sell you.

After looking at the dozen or more options out there I decided to go with this barrel for a pistol build because they are cheap in price without being cheap in quality. I did watch a review from Garand Thumb and he ran one suppressed for tens of thousands of rounds without issue. Mine was great. Nice durable finish, gas hole was where it should be and lined up with the dimple. I have around 500 rounds through it and it hasn't missed a beat. Very accurate at close range but I haven't tried it at longer range. My friend bought one based on my recommendation and he likes his as well. Rosco might be one of the better cost of quality barrels on the market.

I have several Roscoe brand barrels, BCG's and gas blocks. All of their stuff is high quality and definetly punches way above their price. I wouldn't hesitate to purchase any parts from Roscoe. Their packaging is also top quality, that shouldn't matter but it's packaged like their proud of their product, not just in a cardboard tube like most manufacturers. Plan on putting this into a Radian Mod 1 upper receiver.

This is an awesome barrel, great price, very accurate and recommended and used by plaid daddy Garand thumb himself. By this thing now. You won't be disappointed I can promise you that, unless you want to run steel case, I've found it works best with full powered 556 or 223. It won't run LAX 556 reloads consistently, nor will it run Tula 223 consistently. However, it will run federal m193 and m855 no problem, it will also run Fiocchi 223.

This is the first Rosco barrel ive owned and I got it for $89.99 before taxes & shipping. I used this to build a 2-Stamp ADM UIC SBR build and I have to saw this barrel worked perfectly with ADM UR,LR & 13.5" LW handgurd. Also installed TriggerTech Diamond Single Stage, MidWest Ind/Radian Nitride enhanced BCG, BAD Elite Ambi Safety, Precision Armament 556 Hypertap, Railscales grip & scales, JP enhanced bolt & Silent captured spring system & Aero Adj Gas Block, FCD dimpled dust cover, FA & Mag Release, Radian Raptor Charging Handle. Barrel looks machined perfectly and finish is flawless for the price and looks alot better made than Ballistic Advantage who uses to be my go to for barrels but now its gonna be Rosco Mfg

Bought this barrel to put on a budget rifle and these barrels are criminally under rated. These are as good as ballistic advantage and come in a much flashier package than the bubble wrap and plastic sleeve Ba ships their stuff in.
