Our friends at Ballistic Advantage make some pretty sweet AR Barrels. I just noticed that all of their 5.45×39 barrels are on sale through the end of the month. 5.45×39 is a round used in Russian weapons such as the AK74 but recently gained popularity in the AR market due to its inexpensive prices. Unfortunately the least expensive version of 5.45×39 ammunition, 7N6, was banned from import but you can still find standard 5.45×39 ammunition for just over $.20 per round. Ballistic Advantage offers 16 different 5.45×39 barrels including 7.5″, 10.5″, 14.5″, 16″, 18″ SPR, 20″ DMR and more of different barrel contours. All barrels have a QPQ corrosion resistant coating and include a Wolf Extra Power Hammer Spring. This is one of, if not the largest selection of 5.45×39 barrels I’ve seen and they are ALL on sale right now for just $150 each. If you’re like me and stocked up on 5.45×39 ammo before the ban happened or just want to build something a bit different, now is a great time to do it at www.BallisticAdvantage.com.
