The Ideal Barrel For Great Balance Of Speed And Performance

The Rosco Manufacturing Bloodline 16 Inch Midlength Barrel 556 was designed around the military and law enforcement specifications for an improved upper receiver group with a bit of twist and advanced engineering from Rosco.

Excellent Quality

First experience with Rosco and out of the box the quality doesn't disappoint. Excellent fit and finish. For those that are curious the barrel is dimpled for the gas block. Priced right for what you get.

Thanks AT3

Yet to try it

Received my 16" 5.56 barrel in a timely fashion, and it looks great. Comes in quite a fancy box with all the special treatments and the barrel is clean and clear. Looking forward to attaching it to my build and getting ready to fire it!

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.

Very nice barrel

I haven't shot this barrel yet but it appears to be very high quality. The fact rosco adds a small dimple is a perfect touch.
