Hello MDS, I have a problem.
I've had a 300blk from Hanover Armory for a few weeks now.
I've taken it down many times adding lube to preferred surfaces, cleaning after shooting etc. The upper and lower have been separated many many times.
I recently switched out the buffer tube and now the detent for
the rear takedown pin gets
firmly lodged into the back divot in the takedown pin when the pin is in the open position.
I can pop the pin out easily enough, but when I try setting it back into the frame to reattach the upper its solid as a rock.
I need to use a mallet each and every time. My palm cannot get the job done without risking injury or damage to the receiver.
Every part that makes contact with the spring or detent is the exact same as before. I did not bind the spring either.
When I first brought the rifle home everything worked fine. I've taken the receiver extension tube back off,
double checked the detent and spring for damage, cleared the hole of any debris, lightly applied gun butter to ease the process and still I have this issue.
Can anyone tell me why this would suddenly be a problem and how to fix it? I'm this close to taking tin snips and shortening the spring by 1/16 inch until it backs the heck off the pin properly.
Thanks
