View Full Version : Simple, Stupid question, re: Chrome Lining
What does it do for the barrel? Increase the life by decreasing wear? Accuracy? Please un-stupifiy me :(
Increases barrel life by creating a protective, hard surface. Stainless barrels are more accurate than chrome-lined however have a shorter life.

It also makes it easier to clean from my understanding.

Easier to clean is a understatement.

Most noobs first and/or only AR should have a chrome-lined barrel.
Chrome-lined barrels are *much* easier to clean.
They generally don't have corrosion issues if basic cleaning applied.
Higher "lubricity" interface with bullet can offer a tad more velocity (depends on apples-to-apples comparison of rifling nature, etc.)
Most barrels don't wear out in the bore, but in front of the chamber where the barrel metal erodes with the high pressures combined with particulate. A chrome lined barrel erodes far less than a regular steel or stainless steel bbl.
There are minor accuracy tradoffs in chrome-lined bbls over regular bbls, however most shooters may not notice this due to skill and/or lack of match ammo.
Shooting quality match ammo in a stiff chrome-lined barrel (Noveske N4 or Colt HBAR or some of the CMMG MedCon bbls) can still lead to very very accurate results.
