DSA AR15 14.5" Chrome Lined M4 1:7 Twist 5.56 NATO Barrel - With Sight Tower

I have purchased two of theses barrels 6 years apart and they are both equally high quality, accurate, and reliable. I shoot around 1.5 MOA at 100 yards with these barrels and the FSBs on both of them are aligned perfectly from the factory, mine shot dead center with the windage on my rear sight centered. They have a very good dark grey manganese phosphate parkerized finish just like the military barrels and the chrome lined chambers and bores make them very easy to maintain. I highly recommend these barrels for M4 Carbine or similar AR-15 builds. I have mine on a M4 clone build with a pinned and welded A2 flash hider and it is perfect for that application. Thank you DSA for an excellent product.
