School me.. pro's and con's of each? |

Chrome-moly barrel vrs Chrome-lined. School me.. pro's and con's of each? Steel alloy with a chromium added to it (chrome moly) theorized to last longer than... chrome plated (Chrome lined) which is theorized to be more accurate of the 2 umm your kind of 180 out of phase |

Steel alloy with a chromium added to it (chrome moly) theorized to last longer than... chrome plated (Chrome lined) which is theorized to be more accurate of the 2 reversed. But anyways OP, ill cut through the crap. Technically what you are talking about is a barrel steel vs. a process... But i know what you MEAN is chrome-lined vs. non chromelined. So non chromelined does not last as long, and it is more susceptible to corrosion. But it is inherently more accurate than chromelined due to the nature of the process of chromelining. Chromelined lasts longer (1.5-2xish) and is less susceptible to corrosion. It is inherently less accurate than non chromelined due to the nature of the process of chromelining. There are a few different other options out there, and a few exceptions to the rules as far as accuracy goes as well.. but thats all complicated technical stuff and im too lazy to create the wall of text here when the information is readily available with a simple google. There is your information.... bottom line is unless you are a 1k per month shooter (seriously) and you use corrosive ammo you actually will be better suited to a non chrome lined, no matter what the internet tactical commandos here say. |

Chrome-moly barrel vrs Chrome-lined. School me.. pro's and con's of each? "Chrome-Moly" (CRMO for our discussion) refers to the type of steel out of which the barrel is made. There are various grades of CRMO such as 4140 and 4150 that are used in barrels. "Chrome Lined" is a plating that adds wear resistance to a CRMO barrel by making the surface harder, and subsequently easier to clean. The drawback to CRMO is that it is not very corrosion resistant without a chrome lining or other barrel surfacing method such as the Nitride variety. The drawback to Chrome Lining is that the surface isn't always applied uniformly in the barrel, which can degrade accuracy. What is the planned use of your rifle? If it's just going to be a low round count plinker at the range, 4140 steel without Chrome Lining is fine. If you want it to last longer and don't care much about accuracy, 4140 with chrome lining is the ticket. If you want to abuse it, get a 4150 (or other vanadium steel variety) with chrome lining. |

On paper CL should be better & last longer, but... 1 of my AR's has a 1:9 non chrome lined DPMS upper & I have not seen any differences in wear or function or accuracy from my CL BCM or Spikes. All have the same amount of rds. 3K+. So IDK? you are talking a difference of 10k+ round life vs. 20k+ like i said.. the average user will not be able to tell a difference |
