    My awesome Gunsmith skills

    Well, I just wanted to share my awesome gunsmith skills (if you even want to call it that).

    Today, I decided to finish my Centurion Arms C4 rail install. I gave up last night trying to get the rear pin out of my front sight base. Trust me, I tried my hardest to get that handguard cap off without removing the front sight base but it just wasn't possible.

    So after banging on this pin for about 30 minutes, I couldn't get it to budge. I got the front pin to move but the rear pin wouldn't. After further inspection, it appeared as if I peened it and at this point, I knew I was screwed. As a last resort, I pulled out the dremel and started to grind away. Finally, after a little bit of grinding, I was able to get the pin to move.

    With the front sight base removed, I was left with a pretty dinged up FSB. I was told to sand it down and touch it up with some high temp BBQ/Engine paint. It ended up being a perfect match so now you could never tell I even messed it up in the first place.

    Here is my question, I am ordering new pins from BCM due to the one being grind down a little bit. I am anticipating the rear pin to stick out slightly more than it normally would because I had to grind the FSB a little bit on the left side. Will this create any problems or should it be fine? Should I grind a little off of the access pin or should I just leave it as is? I would say I took off a millimeter or a little less than that.

    Lesson learned - I will not be doing this again.

    Here is a picture of what it looked like prior to spraying it with the high temp paint.

    why not grind down a pin sticking out more. Its not like the pin requires a specific length for integrity, so shaving it flush wont do anything issue wise. imo it would be best to flush it out and only take probably 30 seconds with a dremel.

    Okay cool. The FSB pins sit inside of a channel within the FSB, right? I can't see any damage but I'm hoping I didn't do any damage to the inside of this thing after banging on it so hard.

    As long as you didnt oval the holes out or tweak the block, im not thinking any damage was done, but i'd wait for ig or some of the more experienced guys chime in with their 2 cents before you reinstall it.

    I still have nightmares about trying to remove my BCM pins, I sent it to a gunsmith.

    My FSB was banged up from me too, however, the smith got the pins out and they were still fine, the FSB was fine too, yours may be different.

    Yea, I'm ordering new pins just to be in the safe side. Was yours dinged up as bad as mine? Did you use any paint to touch it up? Looking at it closely, it appears everything is still fine. Nothing is bent and it slides back on the barrel just fine. If I'm guessing right, the taper pins the way they are designed do the most holding inside of the channel within the FSB. The channel that the pin rides through and into the cuts on the barrel. As long as the pins hold tight, I don't see if there are any other issues that could arise.

    I can't comment on your gunsmithing skills but your "table cloth picking out skills" are not so awesome.

    Well mine was not as bad at the rear. It was dinged up though, and I got my barrel one time- though it was not a full force hammer blow, it still dinged it.

    I painted my entire rifle with Alymude II so the FSB looks nice now.

    Cool. Yea, I didn't hit the barrel or anything. That rear post though. The reason why it looks like that is because I had to grind it a little bit.
