May have got a dud - Rosco Manufacturing Bloodline 5.56 NATO Barrel

I am very displeased with this barrel. I bought an 11.5" 1:7" twist, 5.56×45mm 4150cmv nitride, with carbine length system and put 1500rnds through it and am very displeased with the quality. I have spent over double the value in ammo on this barrel and still was not able to get this thing to continually group under 3 moa. I have shot factory and handloaded ammo, in a variety of grains 55-77grs, and a variety of powders. Nothing has grouped. This barrel is a giant waste of time. I would understand if it consistently grouped at 2 moa. I get that it is a value priced barrel. Im not trying to shop for champagne on a beer budget here. I had the rifle checked twice by a gunsmith and everything indicates this thing is a dud. I am very displeased to say the least. Bottom line this thing is more useable as a club. I would never depend on this thing to protect my life or my families. Take the $100+ you would spend on this and buy from a more reputable manufacturer such as ballistic advantage, ranier arms,etc... bottom line is if you value your life, your loved ones or any human and you plan on depending on this to protect those people look elsewhere.
