I got my receiver barreled today, and installed the gas tube, if I put the rec. in a vise and level it, then run a long thin straight cleaning rod through the gas tube, the cleaning rod should settle to bottom dead center of gas tube(right?). Then if the cleaning rod aligns with top dead center at mussel, timing should be good?
Also I installed the BHO and the mag catch, the BHO is a little sticky, will this work itself out or should I remove and use a little emory cloth?
When do I need to install locking shoulder?
Is there a way to check for any feed issue at this stage?
