LANTAC UAR, Stripped AR15 Billet Upper (LA00221)
The UAR is a precision machined upper with a special burnished bore that gives a compacted internal surface with a roughness average in micro inches of 16, as opposed to standard bored or milled uppers that are 32-63, or higher. This reduces bolt carrier friction and creates a much smoother operation.
