if the buffer touches the nub on the detent when the upper is closed either the buffer is moving too far forward or the detent pin is too far back.
the position of the carrier in the upper appears to be correct, but then the hole in the lower for the detent appears to be OK,too. do you have another rifle, or access to same to see if your problem follows the part being substituted? i.e. put the upper on another lower and see if it does it to another lower, or see if another upper does it to yours. if the upper is the culprit, look to the barrel nut, see if its loose. you could darken the buffer face with a Sharpie ,and not test to destruction. my only experience with this WAS a out of spec 80% lower that i muffed. Stag's are good to go, but things do happen. |

I think I just realized what happened. The entire time I did NOT have the barrel on it (haven't assembled it completely yet.) And I noticed that when the barrel is in all the way, it seats the bolt backwards about 2 millimeters. This is about enough that the buffer needed to not slam into the detent in my assumption.
So I broke it for nothing.... BUT there is still the problem of the spring being very strong. I don't know how many "coils" are considered countable, but offhand I counted 40. 10.8 inches is the average length of a Carbine Buffer tube though, so it should be a carbine no? |
Yea, some important information you neglected to tell us about.
