are the stainless barrel supposed to be more accurate than the nitrate barrels?
garret l on Mar 14, 2019
BEST ANSWER: Yes it is more accurate, but heats up a lot faster. Generally not the best choice if you are building a combat rifle when you will be shooting a lot of rounds in a shorter period of time. For the avg weekend warrior it will be fine. Just don't blow through ammo like water.
Can this go on a Ruger ar 556?
jeffery f on Mar 17, 2019
BEST ANSWER: I don't see why not. AR uppers in the same caliber are interchangeable.
Who makes this upper?

Are there heat problems with SS?
Jeff B on Mar 16, 2019
BEST ANSWER: If heat were a problem with SS manufacturers would not use it. The amount of heat generated by shooting a round is constant. Heat is absorbed by and dissipated by the barrel. The thinner the barrel profile, the faster it heats up. Likewise, the thinner the profile, the faster it dissipates heat.
