Most AR uppers have a little play between the barrel extension and the receiver. We take it out: a precision stainless shim fills the gap and thread locker seats the extension, so the barrel and upper act as one solid piece. It\u2019s still removable with heat if you ever re-barrel.<\/p>\n
Want the front of the upper trued too? Want the receiver face lapped square before the barrel goes in, so the barrel nut seats evenly? Mention \u201cface lapping\u201d in your request (+$25).<\/p>\n
A popular step for precision and DMR-style builds, and a natural add-on when we\u2019re already assembling or re-barreling your upper.<\/p>\n
