    You can do that. Just about any pin the correct size will work. It does not need to be tensioned to function properly. I bet in a pinch a piece of coat hanger wire will work.

    Might also see if there is a burr you can scrub off with a file or sandpaper.

    Try rotating it as you insert it.

    Those pins can be finicky sometimes, especially if the arms open away from each other. You can try bending it with pliers, but sometimes it's easier just to get a new pin.

    Thanks all Im just so new to this ya know. But everything looks correct ? Its just the pin causing me trouble. I think I read ther is really only 1 way everything fits back togther so its kinda hard to mess up.

    Yep. It can only go together one way and work. You can try to put the bolt in 180 degrees backward and the cam pin can be put in wrong but it won’t assemble all the way.

    They made it so an 18 year old kid can’t mess it up so don’t worry.

    I have taken mine to a grinder and knocked the sharp corners off the ends. Slips in no problem.

    Yep, your pic is looking good. It's just the splaying of the arms that is giving you problems. Like others suggested, try twisting it as you put it in.

    Leave the firing pin out, shove it through the first hole and see where its landing at the hole on the opposite wall. Sometimes they're a bit fiddley, might need turned or wobbled a bit.

    As others have said, knocking the shoulder of the pin down a wee bit with a file may help also.

    You stated this a a bit new to you so I'll pass on an observation. During reassembly make sure the retaining pin is between the head of the firing pin and the shoulder, exactly as you photographed.
    I know of one instance where the retaining pin was in FRONT of the shoulder, so the firing pin would never hit the primer.
    Have fun with that AR!:42:

    I've cleaned up the split end with a file also.

    Most of my older pins are somewhat pointed on the split end, so they go right in.

    I've gotten a couple more recently that were just about cut square off on the split end. They were being difficult, until I tuned them up with the file.

    It seems like all of my BCG's from Toolcraft have pins that don't like to play along. None of the other manufacturers give me issues. Like everyone else said, just twist it and it should go in. You may have to fidget with it a little but it will go.

    After all that I got it back togther this motning. Went to the range and didnt even shoot it . I was taking along a friends girlfriend whom wants too learn to shoot . He wants nothing to do with guns so I told him Id take her along. We spent 2 hours there but I spent the whole time teaching her the basics with the Ruger Mk target 22 cal pistol. She did well . She even shot the 9 mill Smith and Wesson 9c2.0 a bit. Mabey 10 rounds of 9 mill b4 she said lets go back to the 22 cal !! Lol. All in all it was a good day at the range. 20190317_141403.jpg

    Probably 3" magnum slugs. Not for me and my guns, but some fellas like whips, ball gags, and stout recoil.

    Hoooooraaah KG!

    Every young Marine recruit who has ever had to reassemble their Bolt Carrier group under the patient and loving eyes of their Senior Drill Instructor understands your frustration with your firing pin retaining pin! I'm getting a little misty eyed just thinking about it... Like everyone else here has advised, twist the head of the retaining pin back and forth gently until that puppy slides all the way in.

    and BTW.... files are not issued, hence they are not authorized disassembly tools, nor are they authorized cleaning material....

    LOL... YMMV!

    Good to see you out there shootin up a storm! Is that the range in Tiverton??

    Your pin is fine.
    It may seem like a flaw and impossible, but once you look through the other side to line it up and rotate it in, it will be easy from then on.
    I would not make any modifications

    Like others have said, twist & turn as you push - but - that sometimes takes 10 minutes when you're in a hurry. I have a tiny flat sided pick that I use to depress that prong that is misaligned, if it doesn’t fit in the hole on the 1st try.

    I’ve looked for a suitable solid one piece pin that would work but haven’t found a one to date.
