This has me very perplexed.
I just picked up a new M&P10 LE version with an 18" barrel. I've owned, carried and used S&W firearms for years and they never let me down so when I decided to get an AR platform rifle in .308 I looked at a lot of reviews and finally decided on the M&P10.
When I got the rifle home and went to break it down to clean and lube it before going to the range I ran into a problem. The rear take down pin was impossible to work by hand. In fact, to get the gun open I had to put a wooden dowel against the pin and smack it with a hammer a few times.
After closing the gun back up I had to repeat the procedure to get the take down pin to seat fully. Checking with S&W's so called "customer service" was worse than useless and a complete waste of time.
I know that having the take down pin be a bit snug is a good thing but I've never run into this issue before. I've owned, worked with, built and taught AR platform weapons almost continuously since I first qualified with an M16 in 1968. I can honestly say that in 50 plus years, I've never had a take down pin that had to be hammered out of the rifle.
A couple of buddies and I want to go harvest some tasty wild piggies and I'm afraid that if I send the rifle in to Smith, I won't get it back any time in the foreseeable future.
No range trip until I get this figured out so any ideas the board members have would be greatly appreciated.
