Are the Roll Pin kits that are not necessarily advertised/made for the AR-15 safe to use or will they fit most likely even if they may not last as long? Or would they be unsafe or not work at all? Because they are really cheap compared to ones specifically made for guns. But then again, sometimes you get what you pay for. Not necessarily this one but just to give an idea of what I'm talking about: https://www.amazon.com/dp/B0CNLNG8Z1?tag=arfcom00-20 |

There used to be a guy on here, that sold roll-pins for AR's on the EE, I should have snagged some of his kits. The thing is, most AR parts kits do not use roll pins, they use split pins instead. One of the reasons i've used mostly Spike's parts kits over the years is because they used actual roll-pins, don't know if they still do or not. But I definitely wouldn't trust some cheapie chicom pins from amazon. That link you posted looks like those are mostly split pins not roll-pins. |

Check McMaster Carr for the pins, and buy the size you need. They have "Mil-spec" spring pins. I don't know what the drawings say for the M16/M4 spring pins, but I'm assuming that those were standard purchased components when the weapons were designed. |

It’s been a while, surprised anyone remembers. I did not charge shipping. Stopped selling because the usps decided I needed packaging that would have forced me to raise the price way too far. Anyway, FWIW roll or spiral pins are much easier to install than split pins. They become smaller in diameter to fit the hole but retain their round shape as they compress. Split pins do not. They compress in one direction only, like squeezing a “C” closed,making them into an oval shape. I may still have a few sets laying around. If you want one I’ll look and see. Email is the best way to contact me. |

MS16562 - Pin, Spring, Tubular, Slotted Tubular spring pins were invented in the 1940's but did not become common in the US until the mid-1950s, and were quickly standardized by the military. The M14 was the first rifle design to use them (both the tubular slotted and coil type) in its design. There are three spring pins on the AR-15/M16 where the pin is not a standard MS16652 pins, the charging handle catch pin, the buffer bumper retaining pin and the and the forward assist pawl pin. These three pin are shorter than standard, using standard pins in these locations is not recommended. |
