Buster Better Lubricity (actual real term), smoother operation over a phosphated carrier, easier cleaning, unless you shoot suppressed for 4 years and never clean it (looking at you @Matt.Cross)... Phosphated carriers are "mil spec" all the way, but that doesn't mean the real world hasn't out-paced that old standard. Modern technology results in Chromed carriers, Nickle boron carriers (NiB), Black Nitrided carriers, DIamond-Like Coating carriers (DLC), PVD and CVD coatings... Much more efficient operating system, better technology... It's a real thing, and the real deal. Here's a blurb from the Cryptic Coatings webpage: "Cryptic Coatings specializes in bolt carrier groups and BCG coatings. Our PVD and CVD processes are designed to provide reduced friction, lower operating temperatures and increased overall performance and BCG life."

Armed Eye Doc Posted May 15 Report Share Posted May 15 Since you posted in the LAR8 section, be sure to get Rock River compatible bolt carrier. Quote Link to comment Share on other sites More sharing options...

Buster In short, a reduction in the rate of wear imparted by friction to your upper receiver. You've got an aluminum upper and a steel BCG, in terms of hardness and surface finish alone, those two are vastly different and the aluminum will be the one that 'gives' first and foremost. Anything that can be done metallurgically to reduce the friction component will drastically reduce the wear factor for your receiver, which will in turn mean better accuracy and reliability.

Stonebuster Posted May 16 Author Report Share Posted May 16 There are a few of these on GB for 99$. I may get one for my rifle. Thanks to all. Buster Quote Link to comment Share on other sites More sharing options...
