J & T use true Grendel chambers and bolts and I believe most J & T barrels are made by Shaw and are buttoned rifle. The heart of any AR style rifle is the barrel and for shear accuracy you have to pay the price. Most of the high dollar barrels tend to be cut rifled or maybe hammer forged in 5.56? I consider the J & T to be rack grade which may be very accurate depending on the ammo and shooter. If your serious about shooting tiny groups at many hundreds of yards the J & T may not be up to the task. For hunting and the more amateur shooters like me I think the J & T are great rifles. I bought a J & T 16" kit that I really like. My 16" 6.5 Grendel seems comparable to my RRA, Bushmaster, Armalite, DPMS or S&W AR's I've been around.
I had a Colt lower similar to yours and I traded it off because I didn't like the screw in the front of the receiver instead of a push type take down pin. I use my Colt 20" H Bar flat top on a RRA lower with NM trigger.
