Carrier sticking out of upper?
Brother inlaw showed up with a new build ke purchased from the local shop this weekend,and had a question I never thought of.
How much should the carrier stick out of the upper when in battery?
The carrier in his upper sticks out about 1/16" or more when in battery.The gunshop says its right.
Tried a few of my carriers in his new upper and they poke out too,just not quite as much.
So I checked my LMT and Armalite uppers and the rear of the carriers protrude out of my uppers just a hair...maybe .005" +/- depending on the carrier and upper.Pretty close to being flush on all of mine.
What could cause the carrier to stick out so far...out of spec upper receiver?
