| Wondering if you know which trigger PWS uses in their MK116 rifles. I also see that PWS uses an Ionite treatment on the barrels. Does Ionite have benefits over chrome lining or other barrel treatments? Also curious about the projected barrel life ofPWS barrels if anyone has knowledge on this matter. Sorry for so many questions but the PWS site is pretty skimpy on the info. |
| Most linings are better than chrome. Chrome is nice if you are in the field and treat your weapon like a soldier does. It's not bad either, chrome barrels have and will be around for some time. My MK116 just came in and it's every bit as nice as my LWRC, fit and finish wise. The LWRC has much nicer furniture however. I'll have to do a comparison. Some of this will be subjective, and some objective--like weight. I also like the 1/8 barrel as it should have an edge in accuracy with more bullets. Now there's a can of worms to open. |

Think of it this way. When the barrel is rifled, the cut rifling is very crrisp and sharp. Chrome lining is a plating that is applied over the rifling.
It is extremely hard and durable, thus increasing barrel life. The Melonite is a metal treatment, kinda like bluing a pistol frame. It also hardens the barrel and offers outstanding corrosion resistance. Since the Melonite is a treatment it does not effect the rifling it is left as precise as when it was cut. A Melonite treated barrel is said to have a life that of a chrome lined barrel, possibly longer. I have not seen an definitive number. A standard chrome lined barrel will last 12-15 before throat and gas port erosion effect accuracy. However there are reports from defensive carbine instructors of barrels approaching 40k and still acceptably accurate. |

so how does an QPQ ISONITED barrel compare to melonite treated barrel? Or is Isonite QPQ another name for melonite?

Isonite QPQ and Melonite are different brand names for salt bath nitrocarburizing. HighSpeedSteel |
