    First of all, like many of you considering an AR-15 in 7.62x39mm, I read the negative threads and saw the not-so-great reviews on YouTube about the set up. I, too, had my reservations. However, I was sold on the AR platform being that this build was specifically for home defense, but I was not sold on 5.56mm as a home defense ammo. I had a couple Iraqi war vets tell me that they’ve had first hand experience with the 7.62mm being superior in close to mid range combat. So here we are; looking to get an AR-15 that runs 7.62×39 ammo.
    I purchased this upper assembly (which required an additional purchase of the BCG and charging handle, both available through CBC Industries) on March 18th and received my order on March 29th. That’s plenty fast for my needs.
    I appreciate CBC making a BCG available for the 7.62 build, sticking with the same manufacturer helped relieve some apprehension.
    After the rifle was fully assembled, I ran nearly 500+ rounds through it without fail. No FTE’s, no FTF’s. (TulAmmo 124gr FMJ) Only a couple times did the magazines fail to fully push ammo up into the BCG, but that’s no fault of this upper assembly.
    I plan to build a long range 5.56mm for my wife, and will certainly buy from CBC. Great products, great prices!!
