I keep seeing all these rifles in today's age getting Melonited Barrels including some pistol barrels. From what I can see Chrome lining really helps with Full Auto but Melonited/QPQ barrels can be better in Accuracy and still be long life as long as the barrel is a good barrel before it is QPQ.
For hard use I have been on a LWRCi kick for the past 5 years. My goto rifle in 2009-2011 was a Henderson Defense HDM4 with LW19 Chrome lined barrel from 2011 until 2015 was a 14.7 LWRCi M6A1 with Melonited Barrel then I got my First SBR and its a 10.5 M6A2. My go to 16 inch rifle right now is a Troy American gunfighter https://worldoftroy.com/produc...oy-agf-5-56-carbine/ that has been flawless. It has a midlength gas and it works well for what I use it for.
They have all worked well and no issues except they have to be cleaned from time to time.
I am just trying to figure out are LWRCi barrels different type of QPQ and barrel steel than say a Ballistic Advantage QPQ barrel? If so is there a rating of types of QPQ barrels like there are for Chrome lined barrels and Cold Hammer Forged barrels?
