Takedown Pin

Brett248Vista · Aug 23, 2013

The pins on the 15-22 are molded in rather than being machined in like on a real AR. It's not unusual for them to be "tight" the first few times, but it's not normal for them to remain "tight". Once they are worn in, the only thing that keeps them in the closed position are the detents and they should be able to easily be released with finger pressure.

Same Issue With M&P 10

I just picked up an M&P-10. I am having the same issue. The takedown pin cannot be budged without using a hammer and nylon punch. I have removed the grip to ensure the detent and spring were installed properly. They were. To ensure there was no issue with the TD pin, the detent and spring, or the lower receiver, I left the upper receiver detached and inserted the TD pin back through the lower receiver until the detent caught the groove of the TD pin.

The TD pin was now easily manipulated with a thumb or finger and freely moved out of the lower receiver until caught in the opposite groove by the detent. I reattached the upper receiver and began inserting the pin through. It immediately caught in the upper and required a few taps with the hammer to fully insert.

I have thoroughly cleaned and lubricated all parts involved with no improvement. The action, trigger assembly, and general fitment seem to be good. I will have to put a few rounds through to see if that loosens it up a bit.

If anyone has resolved this issue or noticed a difference after some range-time, I would be interested to hear from you.

I have 3 AR-style rifles, and only my Noveske is that tight that I need tools to push out the pins. I probably have about 700 rounds through it so far, and I did have the upper & lower Cerakoted when they were brand new. Initially, I did use a small metal rod wrapped in sandpaper to remove any of the coatings that had been left in the path of the pins. It has loosened up a little over time, but not to the point that I can disassemble it without either using a punch or something similar. I've accepted this, thinking that I'd rather have it snug (aka precise) than loose. My 15-22 is no where near this tight, and pins can easily be removed (as I think I mentioned above) without any tools. I'd shoot the gun for a while (longer than I have) before altering it to make pin removal easier.

ETA: I'd add that since writing my post a few spaces up in this thread, I have sold / parted out a Spike's / DD AR and replaced it with a new one. My Northtech Defense matching set is easily field stripped, and the Noveske matching set is far from it.

Just like everythang bought new, the pins will loosen on their own over time.

I used a nylon pin pusher on my 15/22 and 5.56 when they were new because I couldn't push them out with my fingers.

Now, a year later, both rifle's pins can be pushed and pulled out by hand.

Better too tight than too loose.
