Only 7 left in stock
14.5″ M4 5.56 NATO Bloodline Barrel: This Rosco 14.5″ M4 5.56 NATO Bloodline Barrel was built around the M4 platform and is designed to be the next evolutionary step in the series. This barrel is perfectly suited for your next patrol or duty carbine build. ALL NFA RULES APPLY!
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-15, 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 rifle barrels you need, not just the one we want to sell you.

Great Deal-
I was looking for a cheap barrel, just to slap together some parts I have laying around to make an AR-15. After shopping I discovered that a few dollars more would get me a really really nice barrel. Just finished my build and can’t wait to get to the range. I can’t speak for the accuracy yet, but I have a good feeling about it. It’s a pleasure to work with and build using quality parts. AR-15 Discount is my new GO-TO for all things gun related.
