Black nickel is a derivative of nickel boron. When applying, the material is first coated with nickel boron, then it is treated in a salt nitride bath. This process isn't commonly used due to the expense in treating the bolt carrier twice. This coating is notable because it has all the slickness and ease of cleaning of a nickel boron carrier ...It has their QPQ finish which is essentially a nitride treatment. QPQ is quench, polish, quench. It is extremely slick and cleans up with the wipe of a rag. DLC on the other hand is a coating as is hard chrome. Nitride is a surface treatment. Any of them are superior to phosphate.

The nitriding process serves to enhance corrosion resistance on both the interior and exterior of the barrel. Chrome lined barrels are typically phosphate parkerized to protect the exterior steel from rusting, but this exterior finish does not ...Basically, stainless is used in match barrels because it’s softer steel and therefore easier to cut very precisely. Stainless can be nitride treated but usually isn’t. Normally, stainless has a shorter useful life than carbon steel but most shooters won’t ever see it.

Learn the advantages and disadvantages …Both finishes are durable. Nitride is not only coated on the exterior, but in the barrel's bore too. It permeates the metal to give better rust protection. Phosphate is only done on a barrel's exterior surface and not the bore. This is because mil-spec type barrels are chrome-lined first and chrome won't stick to phosphate or any other coating ...My WMD NiB-X has had zero extraction issues. Perhaps the phosphate bolt in nitride carriers is that the temperature to do QPQ properly is very close to that which could soften the temper on the bolt. That could be dangerous. Been using a QPQ extractor for well over 2000 rounds suppressed on my DDM4 16.1" Middy.Crate and Barrel is a popular home decor and furniture store that offers a wide variety of products for every room in your house.

The Gamma SL muzzle brake will significantly reduce felt recoil and allow for quicker follow up shots and faster split times. Included is also the Stag 13 ...The pencil barrel is the original profile for the AR-15, typically measuring 0.625 inches in diameter. It is known for being slim and lightweight, making it easy to carry and handle. However, due to its thinness, it may overheat more quickly during rapid firing, leading to elastic deformation or warping, which can affect reliability and accuracy.The first barrel had 2000+ rounds and a black finish. The second barrel was brand new and machine finished. Leon asked Nitrofreeze® to cryogenically treat both barrels so that he could compare the results. After cryogenic treatment, Leon used the AR-15 with the new barrel, which had fired only 50 rounds previously.For example, the Palmetto State Armory Freedom 16″ AR-15 Carbine's phosphate coating is durable, but rough. Over time, it tends to catch tiny debris and it's little harsher on the surrounding aluminum receiver. Phosphate coating isn't the best finish for durability and reliability but it 's good enough for the vast amount of people.Sep 1, 2017 · Nitride is easier to clean. While properly performed nitrocarburization treatment is great for a bolt carrier, it is a sub-par choice for the bolt. Reason being is that the nitriding process has the tendency to impart brittleness. This translates to decreased bolt life, usually significantly. The nitriding process involves submerging the steel ...Curious that Geissele is now offering barrels. If they are actually available for sale, that is a good thing. Geissele makes their own barrels in house. The description says they are chrome lined with mag phosphate exterior.
