Description
The LWRCI M6-AK upper is an M6A2 style upper chambered in the 5.45x39mm cartridge. It features a 14.7” barrel with permanently attached A2 flash hider. It has the LWRCI Mark 1 ARM-R rail system and utilizes LWRCI’s patented short-stroke gas-piston operating system. The 5.45x39mm cartridge was developed as the Soviet’s answer to the American and NATO countries 5.56x45mm cartridge. It was chambered in their AK-74 rifles and its ballistics closely mirror those of our 5.56 round.
Model: M6AKS545x39
What this ad says to me:
If you want to closely mirror the 5.56 NATO round, then buy a pair of equal quality AR-15's for less than this upper.
If it's the 5.45x39 and piston system you're after, buy 2 AK-74's with 2 cases of ammo for less than this upper.
If you like blowing wads on a company that's only the best because they say they are, buy this upper.
