Just received a dedicated upper from Tactical Solutions. Mounted it on a Stag Lower. It fit pretty tight, but not where you have to really force the pin to close. The problem seems to be after a few rounds the bolt seems to jam in the buffer tube. Or the action jams to the rear where the bolt will not come back forward without taking the rear retaining pin out freeing the bolt carrier and bolt.
It is suppose to lock on the buffer retaining pin, but seems to "hop" over it and into the buffer tube, jamming up the action, until you punch out the rear pin and open the rifle. That is what I am assuming is going on, with the action jammed up I really cant tell the cause of the malfunction.
I tried it on another 2 lowers, one did the same thing (Stag) the other (LMT) was so tight I could not get the rear pin to lock it down.
Has anyone had this problem ,or know of a solution?
